1. GENERAL INFORMATION

1.1 Introduction

In the Netherlands, graduate schools have been founded for a variety of scientific disciplines. Interuniversity graduate schools are schools in which several Dutch universities participate, as laid down in a formal agreement between the Executive Boards of the participating universities. One of the universities is responsible for the daily organization and administration of the graduate school, including the organization of the PhD educational programme and various scientific activities. These activities are conducted under the responsibility of a scientific director, often, but not necessarily, one of the professors of the university that is in charge of the administration.

The primary aims of graduate schools are to provide additional education and training for PhD students of the participating institutions and to foster scientific contacts and collaboration. For the Graduate School on Engineering Mechanics, the aims have been particularized in the Mission Statement, presented in section 1.2.

Until 2014, Graduate schools could be accredited by the Royal Netherlands Academy of Arts and Sciences (KNAW), which gives a mark of quality. The accreditation was given on the basis of a proposal in which a coherent educational program for PhD students was described as well as coherence in terms of research between the participating teams. Accreditation was given for six-year periods. After such a period an application for renewal of the accreditation could be filed at the KNAW, which consisted of a self-assessment over the past period, together with a peer review based on a site visit, interviews and this self-assessment.

The Graduate School on Engineering Mechanics was founded in 1996 and received a five-year accreditation of the KNAW directly at the first application in 1997. It embraces all research groups that are active in the field at the Eindhoven University of Technology, the Delft University of Technology and the University of Twente, with the Eindhoven University of Technology acting as the commissioner, hosting the secretariat.

In 2001, 2006 and 2012 a peer review of the activities of the Graduate School over the first, second and third period of operation by an international review panel took place and in 2002, 2007 and 2013 the ECOS/KNAW-accreditation of the Graduate School on Engineering Mechanics was renewed. In 2014, the KNAW decided to completely abandon the accreditation procedures for Graduate Schools. This implies that the present period of 6 years is the last one for EM, in which the accreditation label still applies.

The Graduate School on Engineering Mechanics represents the internationally active groups of the Dutch universities of technology in the area of engineering mechanics. The EM-school also co-ordinates and tunes the research activities in the participating groups (e.g. through the 3TU Centre of Excellence), and it has developed a complete graduate course programme in collaboration with the JM Burgers Centre (Graduate School on Fluid Mechanics). It can therefore be considered as the representative scientific platform in the Netherlands in the engineering mechanics field. This platform sets the strategic directions of future research in the Netherlands in the engineering mechanics field, and it is responsible for the quality of future generations of PhDs, who are the primary determinants of the quality of future activities in this area in the Dutch industries and universities. In the Graduate School on Engineering Mechanics, the individual research groups have an essential responsibility in executing their individual research programs. On basis of consensus, the graduate school thereby stimulates certain focal areas of research. More importantly, it exercises

6

a quality control on the level of research, since it has adopted a lower bound for the quality of the participating groups, which derives from the research assessments at the level of the university departments that are commissioned by the Netherlands Association of Universities (VSNU).

1.2 Mission

The Netherlands Graduate School on Engineering Mechanics has been established with the aim to strengthen research and education in the field of engineering mechanics in The Netherlands. The EM Graduate School intends to be a platform that, on the basis of a number of selected research themes, fosters long-term knowledge and skills in the engineering mechanics field. Although operating primarily at a national level, it intends to stimulate international collaborative research projects within the research themes. Within the foregoing global objectives the following more specific objectives can be formulated:

• Training of PhD-students to become qualified independent researchers in the field of engineering mechanics according to international standards. To this end, a series of high-quality graduate courses is developed on specific subjects.

• Co-ordination and tuning of the engineering mechanics research activities in the participating groups. Furthermore, the Graduate School aims at strengthening the available infrastructure for research in engineering mechanics. It can be stated that the present infrastructure meets high international standards. • Selection of the main research themes in engineering mechanics carried out within the EM Graduate School. These research themes are being characterized by a strong international

position of the research in the Netherlands, while at the same time they are of importance for Dutch industry and society.

• Strengthening of the international scientific position and the international visibility of The Netherlands in the engineering mechanics field. • Cooperation with industries and technological institutes to promote the mutual exchange of knowledge on engineering mechanics. • Maintain close connections and cooperate with related fields of engineering. • Stimulate nation-wide thematic discussions, streamlined research strategies and organization of workshops for representatives from industry, technological institutes and project leaders to

discuss the needs of industries with respect to scientific research. • Guarding the standards of undergraduate education in the engineering mechanics area at the Dutch universities. This is done in particular by influencing policies with respect to the

appointment of professors and other senior staff in this area. • Attracting highly qualified engineers, prospective and established scientists to the Netherlands.

1.3 The field of Engineering Mechanics

Engineering mechanics is concerned with the description, analysis and optimization of the static and dynamic behaviour of materials, products and mechanical processes. Solid mechanics is at the heart of engineering mechanics, but is not necessarily identical to it. Traditionally, engineering mechanics is one of the fundamental cores of engineering sciences such as Aerospace Engineering, Civil Engineering, Mechanical Engineering and Maritime Technology.

7

Assisted by a steady growth in computational power, resources and efficiency, new challenges and perspectives for the engineering mechanics field have emerged. Contemporary developments of engineering mechanics include the following major directions:

• Prediction of structural mechanical behaviour from material mechanics and establishment of structure-property relations for engineering materials and structures, including the ultimate failure of the material or structure. The ultimate aim is to bridge the gap between science and technology in the area of materials processing and design, via computational modelling and experimental analysis of the full thermo-mechanical history of material during their formation, processing and final design, in order to be able to quantitatively predict product properties. This equally applies to structures composed of these materials.

• Prediction of the dynamic behaviour of engineering systems with full account of nonlinearities and multiphysical dynamic interaction and experimental identification under operational conditions. This area is of crucial importance in many practical dynamical systems where friction, contact and other nonlinearities have a substantial effect on the dynamic behaviour.

• Optimization of products, processes and systems by means of computer simulations to enhance the reliability and to tailor their mechanical behaviour for the particular application. Here, it is assumed that the simulation of the mechanical behaviour can be carried out in a sufficiently accurate way, while the optimal design is traced numerically. Among typical application areas, the following can be highlighted:

• miniaturization & micro-technology: design, optimization, processing and functionality of MEMS

(micro-electro-mechanical systems) and NEMS (nano-electro-mechanical systems); processing, performance and reliability in SiP (systems in package); low-k solutions in IC-technology; lead-free soldering; 3D printing

• high-tech consumer applications: flexible displays; flexible photovoltaic cells; lab-on-a-chip systems; RF-MEMS wireless technology;

• high-tech materials: metastable materials; shape memory alloys; TRIP-steels; GLARE; Ni-based superalloys; thermoshock materials; high-temperature materials; self-healing materials; thermoplastic composites,

• innovation and optimization in manufacturing: polymer-coated sheet processing in packaging; discrete die forming; damage engineering in metals; paperboard engineering; friction stir welding; additive manufacturing

• dynamics of materials and structures: nonlinear control of motion systems and robotics, vehicle dynamics, tire dynamics, acoustics and control, structural acoustics and noise control, structural health monitoring;

• construction engineering: collision-proof ship hulls; damage control in masonry and concrete structures, • topology optimization of smart structures

As a consequence of the above developments, the traditional boundaries between solid and fluid mechanics are sometimes fading. This happens, for example, in fluid-structure interaction (FSI), in the field of mechanics of materials and in the area of acoustic radiation of structures. In addition, the interactions with other areas of engineering sciences, such as materials technology, thermodynamics and systems and control, become of increasing importance. Finally, it is noted that the successful implementation of the abovementioned developments in practical applications relies on prior experimental validation of the developed simulation tools and physical models. This requires an increasing interaction between computational modelling and experimental analysis.

1.6 Research themes

An important goal of the Graduate School on Engineering Mechanics is the co-ordination and combination of research activities of participating groups. In accordance to this it was decided to group the research activities into three research themes:

1. Computational and Experimental MechanicsThis research theme is related to the potential of modern computational and experimentaltechniques for solving problems in mechanics. Much attention is paid to optimal numericalprocedures and to large-scale computing. Important applications are in the field of crashsimulation of vehicle systems, simulation of production processes, in particular formingprocesses, as well as complex structures in civil engineering and aerospace engineering.

2. Structural Dynamics and ControlThis research theme is related to the dynamic behaviour of engineering structures. Particularattention is paid to nonlinear dynamics and fluid-structure-interaction. Also of importance isthe interaction with control. Important applications are in the field of rotating machinery,noise reduction and drive systems.

3. Reliability and OptimizationThis research theme is related to the development of design procedures based on reliability,as well as to structural optimization with respect to mechanical behaviour. Importantapplications are in the fields of biomedical technology (e.g. heart valves) and in the field ofthin-walled structures.

These research themes fit well with the major directions in contemporary engineering mechanics as described in Section 1.3. Furthermore, they are characterized by a strong international position of the research in the Netherlands, while at the same time they are of importance for Dutch industry and society.

Point of departure in all research themes is the development of models based upon the principles of engineering mechanics. These models necessitate and motivate the development of contemporary numerical and experimental tools for solving engineering mechanics problems. The application of these tools in computer-aided design and production processes results in a decrease in the development time of advanced products, and thereby time-to-market, for instance due to a reduction in the required amount of prototypes. Also, an increase in product quality and a reduction in production and operating costs are worth mentioning, improving competitiveness. The optimal use of computational resources for complex numerical simulations

11

as well as the incorporation of nonlinear phenomena in the modeling is common to all three themes.

Research groups participate, depending upon their expertise and affinity, in several themes:

Group Computational and

Experimental Mechanics

1.7 Education

The most important goal of the Graduate School on Engineering Mechanics is the formation and education of graduate students to become independent researchers in the field of Engineering Mechanics. In accordance with this, the Graduate School offers a national four-year training program for PhD students in the field of Engineering Mechanics. It consists of a programmatic part and a PhD research project, accompanied by a personal plan of education and supervision per PhD student.

In addition to these joint courses the programmatic part contains an individual course program, with initial and post-initial courses selected from the programs offered at participating groups. Furthermore, participation in workshops and summer schools under guidance of foreign visiting lecturers forms part of it, as well as practical work at foreign top institutes.

1.7.1 Course curriculum

The PhD research project covers about 80% of the four-years training program. Research topics are in connection with the research program of the Graduate School. As the research approach within the Graduate School is thematically oriented, research students get the opportunity both to deepen their knowledge in the context of their own project and to broaden their vision on the research field as a whole.

The programmatic part of the training program, including personal and professional skills covers about 20% of the four years training program. The heart of it is formed by a joint series of EM

12

graduate courses, in close connection with the selected research themes. PhD-students can take part in the courses, providing the opportunity to keep track with developments in the field of engineering mechanics outside their own focus of research. EM-graduate full courses all follow a general framework, which consists of two three-day clusters of lecturing, alternated with (computer) exercises to obtain hands-on experience. In principle, staff members of the participating universities teach the courses, inviting (international) experts in the field as guest lecturers where relevant. The programme successfully started in 1998. All courses are evaluated systematically and results are discussed with lecturers and Governing Board. In general, participants are very content with the courses, appreciating their relevance and the new knowledge and information offered. Furthermore, courses enable a fast and effective interaction between research and education. To keep the connection with the selected research themes actual and up-to-date the contents of individual courses is regularly updated. The present courses organized by EM are listed below:

- Nonlinear material mechanics Full course - Stability in Structures Full course - Advanced dynamics Full course - Multi-scale and micro-mechanics Full course - Continuum thermodynamics Topical course

- Optimization and parameter identification Topical course - Solutions methods in computational mechanics Topical course - Solving structural acoustic coupled problems Topical course - Mechanics in microsystems Topical course - Discontinuities, interfaces, fluid-structure interaction, multi-phase Topical course - Experimental engineering mechanics Topical course - Mechanics of large deformations Topical course - Reliability, Lifetime and System Health Topical course

1.7.2 Structure of the Engineering Mechanics PhD course programme for the period 2012-2016

In 2008, a new course programme has been established in the interest of the PhD students and Post-Docs. Key characteristics are: a two-years cycle course programme, formal registration of credit points, more courses and courses of different type (broad or in depth).

Details are provided below:

The minimum educational load for PhD students is 15 credit points (one credit point is equivalent to one ECTS-credit and will be further referred to as EC), i.e. 1/4 of a year. After completing the programme, a PhD student receives a formal certificate, as proof of his/her successful participation in the EM course programme.

13

Boundary conditions:

• The courses have to be attended completely. PhD students who only attend a part of a course will not receive credit points for that course.

• Each individual has to supply a written proof of the successful completion of a local or external course, to be signed by the supervising professor (promoter).

• The EC-equivalent of each course will be determined at 0.5 EC/day. • In order to obtain credit points for an external course that has not been previously

approved by EM, the PhD student must request for an approval prior to the start of the course.

• In order to obtain the EM certificate, a PhD student must have attended the EM symposium at least 2 times during the PhD contract.

• EM publishes a full course calendar on its website. • PhD students who collected a minimum 15 EC, receive a formal certificate, formally

handed over during the annual EM symposium.

Outline of the structure of the EM-courses in the programme:

• Duration of a cycle in the course programme = 2 years. • Full courses (3 EC): 6 day courses covering the wide scope of key areas in EM. Two such • courses are organized every year, i.e. 4 courses in a cycle of 2 years. These courses • include a rapid summary of basics followed by advanced topics that are beyond the MSc

level. • Topical courses (0.5 or 1 EC): 1- or 2-day courses on specific subjects, for a smaller group

of participants. These courses may either strengthen the generic basis or provide specific in-depth knowledge. About 8 such courses are offered in a 2-year cycle.

Recognized courses and allowable share within the programme:

• EM-courses and workshops: PhD courses organized by EM (details below). Minimum share = 8 EC.

• Recognized external courses organized by external graduate schools or institutes and approved by the EM board.

• Master courses given at local institutes to patch missing skills in the training of a PhD student, as required for his/her particular project. If MSc courses are taken, the course exam is compulsory and has to be passed. Maximum share = 5 EC.

Additional courses such as presentation skills, technical writing, etc. can also be mentioned on the certificate. On request of the PhD student, EM will provide the promotor with a list of the EM-courses he/she participated in. On the basis of this list and on the request of the PhD student, the promotor can make a letter stating the full overview of all courses taken in the educational plan of the PhD student applying for this letter.

EM courses All EM courses are integral part of a 2-year programme, listed in the sections 1.7.3 (cycle 2016-2017 and 1.7.4. (Provisional planning cycle 2017-2018)

1.7.3 The Engineering Mechanics PhD course programme for the present cycle 2016-2017. The following EM courses have been lectured as a part of the educational programme:

Title: Solving Structural Acoustic coupled problems Date; Location: January 25 - January 26, 2016 Lecturers: Lopez Arteaga, Wijnant Credit points: 1 Participants: 19 Contents: This course will give an introduction to varies aspects on vibro-acoustics.

It focuses on numerical/theoretical aspects (finite element methods/boundary element methods to solve the Helmholtz equation as well as source localization techniques) but some experimental (specifically source localization) techniques are covered as well

Title: Discontinuities, interfaces, fluid-structure interaction and multi-phase problems

Date; Location: May 09 - May 11, 2016, TU/e Lecturers: van der Zee, Remmers, Huyghe, Brummelen Credit points: 1 Participants: 27 Contents: Interfaces and discontinuities are ubiquitous in science and engineering.

Typical examples are provided by multi-phase problems, boundary- coupled multifield problems such as fluid-structure interaction, and

cracks and discontinuities in solid materials. The characteristic feature of an interface is that it is spatially confined to a surface or to a very narrow region in the vicinity of a surface. In addition, most interface problems have a free-boundary character, which yields a complicated interdependence between the subsystems adjacent to the interface and the geometry of the interface.

This course provides an overview of various aspects of interface problems, with special emphasis on numerical-modeling techniques. Several different archetypal interface problems are considered, e.g., fluid-

structure interaction, crack propagation, bilayers and phase separation. The course identifies the generic features of interface problems as well as the features specific to the various archetypes, in relation to numerical-modeling approaches.

15

Title: Mechanics in Microsystems Date; Location: May 24 - May 25, 2016, TUD Lecturers: Goosen, Sprengen, Ghatkesar Credit points: 1 Participants: 11 Contents: Microsystems play a large part in modern equipment and are used as

sensors, actuators, displays, etc. The mechanical aspects of these micro and nanometer sized structures play an important part in their functioning. Due to scaling effects the behavior of microsystems can be quite different from more traditional systems and other physical phenomenon can dominate behavior. In this course we will look at the mechanics at the very small scale, the physical phenomena and how they can be used or avoided.

The following topics are included:

- Size and scaling effects - Microsystem fabrication and the influences on the mechanics. - Reliability of microsystems. - Mechanics of nano structures. - AFM and other instrumentation.

Title: Advanced Dynamics Date; Location: June 20 - June 22, 2016, TUD and June 27 - June 29, 2016, UT Lecturers: Alijani, HosseinNia, Schwab, de Klerk, Fey, de Boer, Ellenbroek, Schilder,

Vormeeren, van de Valk Credit points: 3 Participants: 36 Contents: Dynamics is one of the fundamentals of Engineering Mechanics. Although

the discipline of dynamics has been present since the 18th century, new engineering applications raise new challenges, and the evolution of computer hardware and numerical methods bring new opportunities for more efficient experimental and numerical techniques. For those reasons engineering dynamics plays a central role for innovation in high-tech systems such as cars, microsystems, wind-turbines, sport equipment or biomedical devices. This course, planned in 6 days, is intended to revise the fundamentals of engineering dynamics and to go in more depth for some advanced subjects that are currently at the center of new scientific and technological developments. Hands-on exercises as well as presentations of engineering applications will be included throughout the course. The course is mainly intended for PhD students willing to refresh their engineering dynamics knowledge and to understand some important advanced aspects they might use in their research or encounter during their professional life. But the course is also open to participants from industries willing to revive forgotten basics and to develop a deeper insight in engineering dynamics.

16

Title: Experimental Engineering Mechanics Date; Location: September 19 - September 20, 2016, TU/e Lecturers: Deshpande, Blaysat, Warnet, Turnhout, Hoefnagels Credit points: 1

Participants: 34 Contents: To design better materials and systems, the mechanical behavior of the material or system in an application, such as damage or failure, needs to be coupled to the deformation of its (micro-)structure in order to elucidate the underlying physical deformation mechanisms. To this end, experimental mechanics seeks to study mechanical deformation through the measurement of forces and strains (under various loading conditions) and, if possible, simultaneous visualization of the microstructural deformation. Such an integration of experimental techniques is often necessary to gain sufficient insight into the complex deformation (micro-) mechanisms. This calls for a careful design of the experiment, as well as a minimum level of understanding of the various existing deformation tests and microscopes in order to select the appropriate experiment, therefore: the graduate course on ‘experimental engineering mechanics’ provides an overview of and introduction to commonly-used experimental deformation and visualization techniques, in which the underlying physical principles will be briefly addressed. The graduate course will cover lectures by experienced researchers on topics including: • design of an optimal experiment considering statistical and systematic accuracies and limitations, also in the context of miniaturization of the experiment, • mechanical deformation tests, including tensile, bending, compression tests, (nano)-indentation, dynamic testing (fatigue, high speed tests), tribological testing (friction, wear), • microscopic techniques for visualizing deformation, including optical microscopy (different contrast modes), electron microscopy (including EDX and EBSD), and surface profilometry, • strain field measurement techniques, including digital image correlation (DIC), • and a short individual lab session (to perform a careful DIC analysis).

Examples from faculty research and literature will be used to illustrate possibilities and restrictions of these techniques. Title: Multi-scale and Micromechanics Date; Location: November 14 - November 16 and November 21 - November 23, 2016, TU/e Lecturers: Deshpande, Doghri, van Dommelen, Geers, Hoefnagels, Hutter, Kouznetsova, Luttge, Nicola, Onck, Pardoen, Peerlings, van der Sluis, den Toonder Credit points: 3 Participants: 48 Contents: Short introduction: Multi-scale & Micromechanics: overview, mathematics & notations, reminders of continuum mechanics. Mean-field homogenization of heterogeneous materials: averaging and mean-field

17

theories, Eshelby and Mori- Tanaka approaches, self-consistent methods , cell methods. Scale transitions: asymptotic homogenization, computational homogenization, thermodynamics perspective on coarse graining. Microplasticity in metals discrete dislocation plasticity, crystal plasticity: single and polycrystalline models, scale size effects. Mechanics of interfaces & thin films: cohesive zone modeling, thin film mechanics. Cellular and porous materials: micromechanics and fracture of foams, plasticity of porous materials. Ductile damage, creep fatigue: physics of ductile damage, micromechanical modeling and characterization, micromechanics of creep and fatigue. Microstructure evolution: introduction to phase field models. Experimental micromechanics: microscopy & analysis tools, multi-scale testing. Lab and training sessions: related to the course subjects. Title: Mechanics of large deformations Date; Location: January 24 – January 25, 2017, UT Lecturers: Ton van den Boogaard, Bert Geijselaers, Semih Perhahcioglu, Javad Hazrate Credit points: 1 Participants: 40 Contents: Equilibrium of forces and moments—or the equations of motion in

dynamics—must be considered in the deformed configuration—the current state. Even for materials with linear stress–strain behaviour, the equilibrium equations are fundamentally nonlinear. In many practical cases only small errors are made if these equations are linearized, but for large deformations this is not valid. For large displacements and rotations and especially for large deformations, concepts like strain and stress, known from small deformation mechanics must be redefined to remain meaningful. This course provides the mathematical and physical basis for a proper analysis of large deformation problems. Equilibrium conditions and stress and strain measures are derived with respect to the deformed and undeformed configuration. Special consideration is given to the formulation in finite element technology with a total or updated Lagrangian approach or with an Arbitrary Lagrangian–Eulerian (ALE) formulation. The course covers the following topics:

1) An introduction to geometrical nonlinearity

Title: Continuum thermodynamics Date; Location: April 10 – April 11, 2017, TUD Lecturers: Sergio Turteltaub, Akke Suiker, Varvara Kouznetsova Credit points: 1 Participants: 33 Contents: In a variety of technologically-important applications, materials are

subjected to large plastic deformations, experience damage or undergo phase transformations. In such cases, the analysis should be carried out using a thermodynamically-consistent model. This topical course is intended to provide a comprehensive overview of the balance principles (mass, linear and angular momentum, energy) within the context of continuum mechanics, which is often referred to as continuum thermodynamics. Special attention will be given to the use of the second law of thermodynamics (entropy inequality) in the derivation of various constitutive theories in terms of affinities and fluxes (Onsager’s approach). In particular, an overview will be given for thermo-elasticity, elasto-plasticity, martensitic phase transformations and damage mechanics. The purpose is to provide the participants of this course a unified understanding of all thermodynamically-consistent material models 1 General introduction

Title: Reliability, lifetime and system health Date; Location: July 4 – July 5 Lecturers: Tiedo Tinga, Richard Loendersloot, Alberto Martinetti, Marielle Stoelinga Credit points: 1 Participants: 16 Contents: For any engineering system it is important that it keeps functioning for a

certain period of time. This is the case for large macro-scale systems like ships, aircraft, bridges and wind turbines, but also for small scale systems like electronics or micro-electronic devices. This capability can be expressed in terms of reliability, life time or system health. The reliability quantifies the probability of failure within a certain time, the life time quantifies the (expected) time to failure of a system and the system health quantifies the evolution of the system condition from virgin to fully damaged.

Knowledge of these concepts is required both during the design of a system and during its operation. In the design process, the focus will be on realizing a certain minimal reliability or life time. In that stage, understanding, modeling and quantifying the material behavior and associated failure mechanisms is essential. Once the system is in operation, the design cannot be changed anymore, but then the way of operating the system determines the loads on the components, and thus affects the reliability and life time. Being able to calculate the expected

21

time to failure, or to monitor the evolution of the system health will assist in operating and maintaining the system properly.

This course provides an overview of the mathematical and physical concepts and principles required to analyze the reliability, life time and system health. The basic principles will be introduced and applications in both design and operation & maintenance will be shown. Also a practical lab session will be organized, where participants can experience the measurement of the system dynamics to assess the system health.

The course covers the following topics:

1) Introduction to reliability, life time and system health (Tinga)

a. Definitions and concepts b. Link with design c. Link with operation and maintenance

2) Reliability (Stoelinga)

d. Basics: probability of failure e. System reliability f. Fault trees g. Application in reliability assessment

3) Design for Reliability (Martinetti)

h. Basic concepts i. Applications

4) Life time prediction (Tinga)

j. Physics of failure: fatigue / creep / corrosion / wear k. Failure and damage models l. Link with load variations m. Application: predictive maintenance

5) Structural Health Monitoring (Loendersloot)

n. Dynamic behavior of structures o. Measuring dynamic response p. Assessment of structural health – damage algorithms

6) Condition monitoring (Loendersloot / Tinga)

q. Bearing / gear condition monitoring r. Vibration / oil analysis

In addition to the lectures on these topics, also a practical session will be organized. In this session, measurements on a dynamic system will be performed in the dynamics lab and data sets will be processed and analyzed to obtain a health or damage indicator.

To stimulate the exchange of information on ongoing research within the Graduate School, the Nineteenth Engineering Mechanics Symposium took place on October 25 and 26, 2016 in congress centre “Hotel Papendal” in Arnhem. One hundred fifty six members of the senior academic staff and PhD-students participating within the Graduate School attended the Nineteenth Engineering Mechanics Symposium.

Prof. Kurt Maute presented a keynote lecture, entitled “Topology Optimization of Problems Dominated by Interface Phenomena”. The topics of the Workshops at the 2016 EM Symposium were “Optimisation and additive manufacturing”, “Multi-physics and coupled problems”, “Experimental Mechanics” and “Dynamics at the small scale” .

Each of the workshops started with a Plenary Introduction by the Workshop Organizers on the trends and challenges of the topics of the workshops. Next, two of the actual Workshops were scheduled to run in parallel on the first Symposium day, whereas the other two were scheduled to run in parallel on the second Symposium day. Each Workshop consisted of two parts, separated by a break. Each part consisted of two presentations by PhD-students/Postdocs.

In conjunction to the oral presentations there was a PhD-students presentation contest, awarding a prize for the best PhD presentation at each of the Symposium Workshops. Members of the jury were the Workshop Organizers.

Winners of the PhD-students presentation contest were: Masoud Dorosti (TU/e) with a contribution entitled “Iterative Pole-Zero model updating for prediction of performance variables”, Emiel van de Ven (TUD) with a contribution entitled “Imposing the Minimum Overhang Angle in Topology Optimisation for Additive Manufacturing”, Hao Thi (UT) with a contribution entitled “Experimental Investigation of Limestone Powders using Different Shear Devices” and Farnaz Tajdari (UT) with a contribution entitled “Numerical modeling of electrical-mechanical-acoustical behavior of a lumped acoustic source driven by a piezoelectric stack actuator”.

In two poster sessions 103 PhD-students and Postdocs of the EM Graduate School presented their current research project. This resulted in stimulating discussions on running projects. In conjunction to the poster sessions a poster contest was organized in which a jury selected the best three contributions. The jury consisted of the following members: Dr.ir. M.B. (Matthijn) de Rooij (chairman), Dr. C. (Can) Ayas (TUD), Dr.ir. E. (Emanuela) Bosco (TU/e), Drs. M.M. (Mario) van Wingerde (M2i).

Winners of the poster contest were: J.D. Brandsen (TUD) with the poster “Shape Optimisation for Dynamics Fluid-Structure Interaction Problems ”, A. Mannheim (TU/e) with the poster “Towards viable nuclear fusion reactors”, S. Liu (UT) with the poster “Parameter study of Friction Surface Cladding of AA1050 on AA2024”.

The contributed posters are published in an information brochure. The winning contributions can be found on the EM website http://www.em.tue.nl/history/index.php/6

Additional remarks:

• The Annual Report 2015, with information on participating research groups, was published in2016. It was distributed among participants and relations of the Graduate School.

24

• There was a meeting of the Advisory Board of the Graduate School on Engineering Mechanicson October 26, 2016, which took place after the Nineteenth Engineering MechanicsSymposium. At this meeting the future strategy and directions of the EM Graduate Schoolwere discussed.

• There was a meeting of the board of project leaders on October 26, 2016, in which the EMactivities were evaluated and the Nineteenth Engineering Mechanics Symposium wasdiscussed. Plans for the Twentieth Engineering Mechanics Symposium, to be held 23-25October, 2017 in Hotel Papendal in Arnhem, were also discussed with all faculty memberspresent. The planned workshop topics for 2017 are: “Processing and manufacturing”,“accurate and fast computing”, “Fracture and damage mechanics and “Non-linear dynamics”.

1.9 Memberships:

1.9.1 Memberships Regular Membership – Group based The regular membership of the Graduate School Engineering Mechanics is based on the admittance of a 3TU research group to become a group member of the School. The membership of a group is based on three criteria:

• Research programme of the group:

The programme should fit in the mission of the EM graduate school and there needs to be asolid basis for co-operation between the scientific group members and other members in thegraduate school. The group’s research programme must have a critical mass that lies wellwithin EM’s scope.

• Scientific performance and quality:

A new research group can be admitted to EM: (1) on the basis of a proven scientific trackrecord that underpins the quality of the group leader and faculty members, for a group withestablished scientists; (2) on the basis of good expectations for scientific quality andperformance for the group leader and faculty members for a new (young) group. If a new EMgroup has previously been assessed by QANU, the requirements outlined in section 1.9.4 forexisting member-groups apply for the new group as well.

• Expectation for integration in the graduate school:

The integration of a new group within EM implies an active participation in the execution ofEM’s PhD course programme and a regular participation of PhD students in the coursesoffered by EM. Group members are expected to participate in the annual EM symposium topresent their scientific progress in the oral and poster sessions.

Group based members of EM either fall in one of the following categories:

• Faculty members

Faculty members are junior (assistant professor) or senior (associate or full professor)researchers appointed at the research groups by one of the respective universities. They have

25

a prime responsibility in supervising the PhD students and Post-Docs during their research projects, and in assisting all PhD students during their PhD educational programme. A high quality of the supervision is one of the key requirements. Faculty members from an EM research group can be voluntary member of EM if their research focus fits in the EM research programme. As a member of the Graduate School EM, faculty members are expected to actively contribute to the knowledge dissemination (PhD course programme) and knowledge exchange (EM symposium).

• Post-Docs

Post-Docs are young researchers with a PhD degree, who actively contribute to researchprojects in the participating research groups. They can take benefit of the EM courseprogramme and they are expected to participate and contribute to the yearly EM symposium.They can also play an active role in the Graduate school, by assisting in the PhD educationalprogramme.

• PhD students

PhD students are the research members of the Graduate school, aiming to obtain a PhD withthe support of the Graduate School and the educational part thereof. The PhD projects areproposed by the supervisors and typically fit within the scope of the EM research topics. PhDstudents belonging to member groups are admitted to the Graduate School on proposal ofone of the supervising faculty members (also EM member). They are expected to fully attendthe EM course programme for 15 ECTS and they are expected to participate and contribute tothe yearly EM symposium.

The membership of a group involves a yearly financial contribution, and an individual (small) contribution to the EM-symposium. The group and individual fees will be determined yearly by the governing board of the Graduate School. For the yearly fee, full access to the educational programme for all subscribed group members is granted.

MSc student membership

Excellent MSc students from an EM research group (i.e. an EM group membership as defined in section 1.1 applies) that are following a MSc-PhD Graduate programme or who have been identified as potential PhD students in the master phase already, can be admitted as a MSc student member of the EM Graduate School. These students need to be registered in one of the adhering Master programmes of the EM graduate school. MSc student members can be admitted to the Graduate School upon nomination of the MSc/PhD supervisors (EM members). Admittance implies that MSc student members are allowed to participate in the EM PhD educational programme and the EM symposium.

Associate Membership – Individually based

26

Individual faculty members who are not part of an EM research group (as defined in section 1.1) can be admitted to the Graduate School as an associate member. They can also propose a maximum of 2 PhD students or Post-Docs to become an associate (PhD student or Post-Doc) member. Note that only 1 faculty member from a group can be an associate member. A larger participation in EM necessitates a group membership. Associate members of EM can be (1) researchers from a non-EM research group of 3TU, (2) researchers from Dutch non-3TU research groups that have an established scientific track record of high quality in engineering mechanics or (3) established researchers of high quality from a non-Dutch group.

The associate membership implies that Associate members can participate in all EM events, including its educational programme. Associate members (faculty, Post-Doc or PhDs) have to contribute financially to the activities (including EM courses) in which they participate.

Industrial Membership

Companies and institutes with long-term research activities in the field of the Graduate School can request an industrial membership of the Graduate School Engineering Mechanics. The industrial membership grants full and free access to all courses of the EM course programme for research employees working in the company. Moreover, as an industrial member, researchers from these companies or institutes can attend the EM symposium, where they can also actively participate in the poster sessions. For registration at the symposium, the EM-researchers regular fee has to be paid.

The industrial membership of a company or research institute involves a yearly financial contribution, and the individual contribution for participation to the EM-symposium. The level of the company and individual symposium fees are determined yearly by the governing board of the Graduate School.

1.9.2 Selection, admission criteria and procedures

Group membership

A group membership is granted by the Board of the Graduate School. The group leader sends a written motivated request to the scientific director. The Board decides on the basis of all criteria and arguments provided. Once the group is admitted to EM, all group members (faculty, PhDs, Post-Docs) can subscribe to EM by completing subscription. The subscription forms of PhD students and Post-Docs must be approved and signed by the direct project supervisors.

MSc student membership

Excellent master students, who wish to become an MSc student member, can fill in a subscription request. This request needs a separate motivation from the responsible supervisors, accompanied by a list of course marks obtained in the MSc course programme. The scientific director decides on the basis of all information provided.

27

Associate membership

An associate membership is also granted by the Board of the graduate school. A formal request has to be sent to the scientific director. The Board decides on the basis of the established contacts with EM members, the embedding, expected integration and contribution to the EM graduate school.

Industrial membership

An industrial membership can be granted by the Board of the Graduate School to companies or research institutes with a strong interest for the EM research activities. To this purpose, the company or institute sends a written motivated letter to the scientific director. The Board decides on the basis of all criteria and arguments provided. Once a company or institute is admitted to EM, its research employees can freely participate in the course activities of the Graduate School.

1.9.3 Double memberships

Faculty members

Faculty members can be member of more than 1 graduate school. They are nevertheless expected to play a substantial and active role in each of the graduate schools in which they participate. To be admitted to the graduate school, at least 25% of the research activities should fit in EM’s research programme.

PhD students and Post-Docs

Researchers (PhD students and Post-Docs) can be member of one graduate school only (KNAW requirement).

1.9.4 Quality monitoring & control

Quality expectations

The Engineering Mechanics graduate school expects all its group members and associate members to aim for a contribution to a high quality research programme. This includes high quality publications with a good citation impact, keynote lectures, patents or inventions, editorial roles in international journals, memberships of international assessment committees, etc. In terms of PhD supervision, a good progress monitoring procedure is expected. It is the prime responsibility of the group leader to work towards these goals.

Independent assessment

Every 6 years, the quality of the research programmes is assessed by QANU. All research programmes are evaluated in terms of quality, quantity, relevance and viability. The outcome of this assessment constitutes the prime feedback on the quality of the research programmes. The quality of the PhD supervision is monitored through direct feedback from PhD students, either individually or through the PhD student board.

28

Monitoring

As a minimum threshold for scientific quality, the QANU marks for quality, quantity, relevance and viability, according to the most recent version of the SEP protocol, have to be at least 3, 3, 3, 3, respectively.

In case a research group underperforms as apparent from the QANU assessment its membership will be reconsidered by the EM Board. If the supervision of an individual PhD student lacks quality, the EM management team will directly contact the responsible supervisors to address the problem.

1.9.5 Additional provision

All situations for which this regulation does not apply will be handled by the Governing Board of the Graduate School.

1.12 Overview of co-operation

1.12.1 Internal co-operation

With reference to its mission statement the Graduate School on Engineering Mechanics fosters the co-operation between participating research groups. This has resulted in an increasing number of joint research projects that received substantial input from different EM-groups. Joint projects for 2016 are summarized in Appendix A.

1.12.2 External co-operation

Within the field of mechanics of materials, the Graduate School on Engineering Mechanics has a long tradition of co-operation with one of the former four leading technological institutes, namely the Materials Innovation Institute (M2i). In recent years, M2i had to change its operational roads in financing research, whereby the present route makes use of the STW-HTM calls, in which M2i represents the industrial partners. The EM projects in this institute form a coherent program that concentrates on forming processes and on the fundamental understanding and the predictive analysis of a number of carefully selected generic industrial problems. The main challenge within this program is the accurate prediction of mechanical properties of materials with complex microstructures, in view of their application in micro-systems (functional materials) and various engineering manufacturing processes. Establishing micro-macro structure-property relations with a particular emphasis on the improvement of materials, processes and products at various scales, is thereby a key issue tackled both experimentally and numerically. The scientific work in this area directly supports the long-term strategy of the industrial partners involved, by acquiring fundamental insight that leads to improved materials and processes. At the same time, the investigated applications in several projects are fine-tuned to a particular industrial request, which provides direct answers to specific engineering questions in industry. The EM Graduate School participates in M2i with 2 clusters (cluster 1 on ‘Virtual shaping and structural performance’ and cluster 2 on ‘Multi-scale fundamentals of materials’).

The Graduate School on Engineering Mechanics also co-operates with other universities, research institutes and various industrial partners.

External Co-operation: Education

With respect to education the EM Graduate School co-operates with other Graduate Schools. It has been agreed that the PhD Students of the EM and JMBC (fluid mechanics) Graduate Schools will be enabled to follow each other’s courses. The same holds for PhD students of the EM Graduate School and the Belgian National Graduate School in Mechanics (GraSMech).

31

1.13 External developments related to EM

The research schools Engineering Mechanics (Solids) and J.M. Burgers Centre (Fluids) jointly compose the 4TU Research Centre of Fluid and Solid Mechanics. There is a long tradition of co-operation between the two research schools. The organizational structure of the research schools and their embedding in 4TU and the Netherlands is shown in the scheme below. At the international level, the two research schools are represented by the Netherlands Mechanics Committee (NMC), through which all formal communication with international scientific organisations (IUTAM, IACM, EUROMECH, etc.) flows.

In 2014, the students enrolled in the joint EM-JMBC graduate programme (supported by NWO) started the PhD phase. Four students are presently working on their PhD projects, funded by NWO through the Excellence Track ‘Fluid and Solids Mechanics’.

The research programme of the joint EM-JMBC graduate programme is composed of the core research areas in Fluid and Solid Mechanics. The Solids pillar in engineering mechanics is concerned with the description, analysis and optimization of the static and dynamic behaviour of materials, products and processes. Solid mechanics is at the heart of engineering mechanics, through which it plays a vital role in economy and society. The Fluids pillar is concerned with the description, analysis and optimization of fluid flows. It is at the heart of phenomena in our environment and is important for a multitude of industrial, biomedical and environmental processes. The interaction between fluids and solids in many engineering problems across the scales, constitutes a natural common part between both disciplines. Solid and Fluid Mechanics play a significant role in many areas of applications that are relevant for our economy, our society and the preservation of our environment. Solid and Fluid Mechanics are a core part of the educational programmes of a number of disciplines, e.g. Civil Engineering, Mechanical

32

Engineering, Maritime Technology, Applied Physics, Aerospace Engineering, Applied Mathematics and Chemical Engineering.

The financing of the Graduate Schools has changed considerably, and will be effective from 2016 onwards. As a result of the actions taken by SODOLA and in agreement with the VSNU, the boards of the universities have decided to provide financial support to the interuniversity graduate schools, like EM. For 2016, EM received a financial support of 50 kEuro from the Board of TU/e and in kind support of 50 kEuro from the Department of Mechanical Engineering of TU/e.

In 2014, the accreditation system of KNAW has come to an end. KNAW decided that it is no longer their responsibility to judge the scientific quality of the graduate schools, since this is largely embedded in the research evaluation of the different departments. On the other hand, the educational part is systematically more integrated in the local graduate programmes that each of the universities is developing. At present, discussions are ongoing to embed the quality mark of our graduate school in the 4TU context.

8.1 Non-linear dynamics of mechanical systems

The numerical and experimental study of non-linear and in particular non-smooth mechanical systems, such as systems with friction, impacts or other constraints are key activities in this sub-theme, and play an essential role in the modeling and analysis of advanced mechanical systems. The research on these phenomena is highly relevant in many engineering applications (friction in high-performance/high-precision systems, drill strings, high-speed milling, hybrid control systems etc.). Numerical aspects are notably difficult, but are becoming more and more feasible with increasing computer power. Related to research theme “Structural Dynamics and Control”

8.2 (Structural) acoustics and noise control, optimization This sub-theme deals with various structural vibrations and the associated sound radiation. The focus is on the one hand on numerical/computational tools for acoustic models, and on the other hand on the experimental validation of those tools. Subsequently, both passive and active means for acoustic noise suppression are investigated. Several mechanical applications are used as benchmark examples, particularly tire–road noise. The development of tools for optimization is essential in the dynamic behavior of mechanical constructions. Related to research theme “Structural Dynamics and Control”

8.3 Vehicle dynamics, tire dynamics and control

Vehicle Energy Management Systems Topology Design Research is done on energy management of the complete power train, including the design trade-offs for hybrid vehicles with an internal combustion engine and an electromotor. Advanced model-based optimisation methods, like dynamic programming, are used for the off-line generation of optimal trajectories for the variables that dictate the energy supply from the

37

combustion engine and/or the electromotor. We started a new research project on a hybrid truck. Vehicle Dynamics and Tyres The group is responsible for the research and teaching in vehicle dynamics. The research focuses on modeling, analysis and control of articulated vehicles, and modeling and analysis of vehicle tires. For the latter, extensive use is made of the flat plank tire tester in the Automotive Engineering Lab. The tire research is linked to the tire–road noise research referred to above. Related to research theme “Structural Dynamics and Control”

8.4 Mechanical Design and Vision The mechanical design group Construction and Mechanism is jointly headed with Prof.Dr.Ir. M. Steinbuch (Control Systems Technology). Dr.ir. P.C.J.N. Rosielle leads the activities in the C&M lab, which comprises on average 6 PhD students and about 10 MSc students. Focal point in the lab is the construction and design of advanced, novel mechanical systems. Related to research theme “Structural Dynamics and Control”

8.5 Systems Design Optimization Optimization methods to support systematic design and improvement of complex engineering systems are investigated. We concentrate on simulation-based design optimization in the context of manufacturing system and distribution centre networks, manufacturing machines, automotive systems, and micro-mechanical systems. Optimization methods and tools are being developed that can deal with typical governing characteristics such as: one or more computationally expensive computer simulation models in the loop, a mix of continuous and discrete design variables, stochastic design variables and responses, and dynamic response behaviour. The development of techniques for approximation, meta-modelling, and lumped-parameter modelling that can be utilized in the optimization plays a central role in our research work. Furthermore, methods for design optimization of multidisciplinary and multi-level decomposed systems have our special interest. Related to research theme "Reliability and Optimization".

8.6 Control of Manufacturing Systems

In this sub programme two main streams can be considered. The first stream considers a class of manufacturing systems that can be approximately modelled by means of a continuous time fluid or flow model. For this approximate model, standard techniques from control theory can often be used to design controllers. As the manufacturing system has a discrete-event nature, a connection between the discrete event plant and the continuous time controller has to be developed. Continuous time signals have to be converted to discrete-events and measurements of discrete states need to be filtered for a better control performance. Currently available flow models often ignore variability, whereas queuing theory often considers only steady state behaviour. For that purpose new (mathematical) models need to be developed that include both variability and dynamics. It is clear that preferably these models should be suited for applying standard control theory in order to control these systems.

38

The second stream considers the control of a network of servers through which many types of jobs flow, where it is assumed that servers require a setup time when switching between types. Such networks can be used to model complex communication, traffic or manufacturing systems. Related to research theme “Structural Dynamics and Control”

8.7 Nonlinear and hybrid dynamics

In this subprogram two main directions can be considered. First, general questions of nonlinear dynamics and control of mechanical systems including switched (hybrid) systems are studied. In recent years hybrid systems attracted a considerable attention due to possible applications in various fields of science and technology. The theory of hybrid systems is far from its completeness. Therefore it is of interest to further develop methods of analysis and design for such systems. In this research particular attention is drawn to the following two questions: analysis of oscillations in hybrid systems and formalization of some mathematical models of hybrid systems using the formal languages approach. The formal language used is Chi developed in the Systems Engineering group. The second direction of the research is to study applications for the theoretical results in the framework of systems engineering. Nowadays complex manufacturing machines contain discrete-event and continuous-time parts with interactions between the components. These interactions can result in nonlinear dynamical phenomena that should be taken into account during design and real-time control of the machine. This research theme has a strong relation with the topic Embedded Systems (within the Institute for Programming and Algorithmic). Related to research theme “Structural Dynamics and Control”

8. Short description of subprogrammes related to research school EM 8.1 Multi-scale Mechanics & Structure-Property Modelling

Upscaling from microstructure towards engineering properties requires advanced methods to extract relevant information from small scales and reveal the emergent behaviour at larger scales. The subprogramme targets this goal through the development of advanced homogenisation and multi-scale approaches, with a challenging application perspective. This subprogramme plays a central role in the research portfolio and can be identified in most of the research projects. Among the topics addressed are: • multi-scale mechanics as a link between materials science and materials engineering:

homogenisation theories and models, study of the collective behaviour of small-scale processes, structure-property relations for complex microstructures

• multi-scale methods for lattice networks, e.g. based on an extension of the quasi-continuum method (applied to paper and electronic textile)

• discrete-continuum transitions: from dislocation pile-ups to crystal plasticity • diffusionless phase transformations, e.g. martensitic transformations as used in TRIP steels

and metastable steels • microstructure evolution: substructuring, patterning, self-organisation etc. • path or history dependency in material deformation • time-dependent mechanics of thin films used for systems-in-foil

8.2 Computational and Experimental Micromechanics

The ultimate performance of materials and high-tech microsystems originates from the mechanics at underlying characteristic length scales, at which microstructures play an intrinsic role. To achieve a comprehensive understanding of these phenomena, this subprogramme focuses on the development of advanced physical models, computational tools and state-of-the-art experimental techniques to study them at the micro-scale. Attention is given to the mechanics of different engineering phenomena that emerge from the micro-scale on the one hand and from the mechanics of microsystems for small-scale applications on the other hand. Special emphasis is given on flexible electronics applications such as rollable displays and roll-to-roll production of solar cells and organic light emitting diodes (OLEDs). The latter have great technologic and commercial value, while stretchable electronics has the potential to open up a realm of possible applications in or around the human body, such as sensitive prosthetic skin or

53

neuron- or retina-interfaces, e.g., for control of epileptic attacks. In these devices, the functionality is delivered by integration of, often brittle, micro-electronic components into a compliant, often polymer, substrate in order to make the device flexible or even stretchable. A primary concern is the reliability, because the systems can be highly fragile and are subjected to large thermo-mechanical loading during manufacture and use. Among the topics addressed are: • modelling of the mechanics and physics of micron-scaled plasticity: dislocation dynamics, µ-

plasticity problems, thin films, crystal plasticity • computational-experimental analysis of the mechanics of single phases and metallic

polycrystals, including size effects: grain boundaries, grain size effects, orientation-texture evolution, strain gradient effects, surface grain effects, strain path effects

• mechanics of microsystems, including MEMS, NEMS and substructured materials, size dependent properties

• thermo-mechanical and hygroscopic deformation of polymer films used as a substrate for flexible electronics

• delamination of the copper electronic wiring from the rubber substrate in stretchable electronics

• development of global digital image correlation (DIC) and integrated DIC to bridge the experimental work in the multi-scale lab to the modelling work done in parallel

8.3 Damage, Fracture and Reliability

The lifetime and reliability of engineering components and devices at all length scales are governed by damage and fracture of their constituting materials and interfaces. This subprogramme develops the in-depth understanding of all the related failure phenomena, and provides powerful models and computational solution strategies, together with dedicated integrated numerical-experimental identification methods. This subprogramme focuses on quasi-brittle damage, ductile damage and interface damage. Among the topics addressed are: • advanced 3D continuum ductile damage models • numerical methods to nucleate and propagate 3D cracks from continuum damage fields • interfacial failure in systems-in-package • mechanics of failure in fibrous networks (paper, paperboard, electronic textile) • thermo-shock failure in ceramics • functional damage as the result of dynamic overstraining in brain tissue

8.4 Free-Boundary & Interface Problems

Many problems in science and engineering are characterized by a connection between disparate subsystems at a common boundary or, similarly, by a fundamental change in the behavior of a single system across an infinitesimally thin layer. Typical examples are dynamic and thermodynamic interactions between a fluid and a solid, the interaction between two distinct immiscible fluids, or the intrusion of a tumor into healthy tissue. Generally, the interface between the subdomains constitutes a free-boundary, i.e., it is not fixed, but its motion is interconnected with the (initial-)boundary-value problems on the adjacent subdomains. Interface and free-boundary problems pose fundamental challenges to numerical simulation methods, on account of the resolution requirements at the interface and/or the complicated interdependence between the boundary-value problems and their domain of definition. A central theme in the research of the MEFD group is the development and analysis of advanced numerical techniques for interface and free-boundary problems.

54

8.5 Computational Fluid-Structure Interaction

A particularly important class of interface problems is fluid-structure interaction. In accordance with the reductionistic approach that pervades modern science, the fields of fluid and solid mechanics have historically developed independently. In fluid-structure interaction, a proper understanding of both subsystems is required. In addition, the interface between the fluid and the structure introduces additional complications, on account of its free-boundary character and the nontrivial interconnection between the fluid and structure subsystems via boundary conditions. The disparity between the fluid and structure subsystems moreover generally reflects in a wide range of length and time scales in the aggregated problem. An important focal point of the group pertains to the development and analysis of efficient iterative solution techniques and advanced finite-element discretization methods for strongly-coupled large-displacement fluid-structure-interaction problems.

8.6 Microsystems

The Microsystems subprogramme focuses its research on the investigation and development of novel microsystems design approaches and rapid, flexible out-of-cleanroom micro-manufacturing technologies for microsystems. Our application focus is on microfluidic chips, biomedical microdevices, and soft microrobotics. Our approaches are often biologically inspired, translating principles from nature into technological innovations. The subprogramme is divided into 4 topics: (1) Micro-manufacturing technologies. The emphasis is on out-of-cleanroom technologies such as laser micro-manufacturing, soft lithography, on-foil processing, and 3D-printing. The basis of this topic is the new Microfab/lab managed by the group. (2) Microfluidics. In microfluidic systems, active control of fluids and species is essential. Examples are fluid pumping, mixing, mechanical actuation, micromechanical probing of cells and tissues, and biomolecule capture for diagnostics. We develop and apply micro-actuators, responsive surfaces, and magnetic bead actuation systems, to realize these functions. (3) Biomedical microdevices. In collaboration with biological, biomedical, and clinical groups, we develop biomedical microdevices to study and understand the behavior of cells, tissues, and organs. This work is aimed at learning about health and disease, and eventually developing novel therapies and medicines. Specifically, we develop organs on chips as in-vitro disease models focusing on brain and cancer, and we study mechanical properties of single cells. (4) Micromechanics. Micromechanical actuators and sensors can be found in many areas. We work with industrial partners to develop relevant technologies for these applications, in wearable sensors for healthcare & lifestyle, water quality, and advanced sensors and actuators for lithography machines. A new and exciting area we are currently expanding is soft microrobotics.

8. Short description of subprogrammes related to research school EM 8.1 Free-Boundary & Interface Problems

Many problems in science and engineering are characterized by a connection between disparate subsystems at a common boundary or, similarly, by a fundamental change in the behavior of a single system across an infinitesimally thin layer. Typical examples are dynamic and thermodynamic interactions between a fluid and a solid, the interaction between two distinct immiscible fluids, or the intrusion of a tumor into healthy tissue. Generally, the interface between the subdomains constitutes a free-boundary, i.e., it is not fixed, but its motion is interconnected with the (initial-)boundary-value problems on the adjacent subdomains. Interface and free-boundary problems pose fundamental challenges to numerical simulation methods, on account of the resolution requirements at the interface and/or the complicated interdependence between the boundary-value problems and their domain of definition. A central theme in the research of the MEFD group is the development and analysis of advanced numerical techniques for interface and free-boundary problems.

8.2 Computational Fluid-Structure Interaction

A particularly important class of interface problems is fluid-structure interaction. In accordance with the reductionistic approach that pervades modern science, the fields of fluid and solid mechanics have historically developed independently. In fluid-structure interaction, a proper understanding of both subsystems is required. In addition, the interface between the fluid and the structure introduces additional complications, on account of its free-boundary character and the nontrivial interconnection between the fluid and structure subsystems via boundary conditions. The disparity between the fluid and structure subsystems moreover generally reflects in a wide range of length and time scales in the aggregated problem. An important focal point of the group pertains to the development and analysis of efficient iterative solution techniques and advanced finite-element discretization methods for strongly-coupled large-displacement fluid-structure-interaction problems.

8. Short description of sub programmes related to research school EM

8.1 Scientific Computing

The main emphasis in this program is on analysis and numerical simulation of problems arising in technology. Research is often induced by specific applications, yet being seen as part of a larger area where mathematical tools and in particular numerical methods can be applied. Hence both fundamental (numerical) research and applying the results to specific applications are typical for Scientific Computing. At present, all applications lie in fluid dynamics, optics, electronics and materials science directed towards energy applications. No applications exist at this moment in engineering mechanics.

8.2 Applied Analysis

The main emphasis in this program is on mathematical analysis of technological problems. Research is often fostered by specific applications, after which it may trigger more fundamental, and thus more generally applicable research.

8.2.1 Mathematical Methods in Plasticity

Dislocations are the carriers of microscopic plastic deformation. In this project we develop rigorous mathematical methods for the upscaling of a large number of such dislocations, with the aim of constructing a rigorous derivation of mesoscopic crystal-plasticity models.

8.2.2 Fundamental Analysis of (Non-Linear) Evolution Problems

Our research in functional analysis is concentrated on evolution equations. An inspiring source of inspiration are non-linear evolution equations arising from free boundary value problems in quasi-stationary fluid dynamics (Stokes flow, Hele-Shaw flow, polymer flow).

The subprograms within 8.2 are related to research theme “Mechanics of Materials”.

8. Short description of subprogrammes related to research school EM 8.1 Structural tailoring, design and optimization

The demands of high-performance, structural integrity, durability, low weight, and minimum cost pose an important challenge to structural designers. New materials may assist in satisfying some of these demands, but at the same time give rise to significant new problems for the designers. Furthermore the structural design can no longer be seen as an isolated activity, but must play its part in a multi-disciplinary approach to the design of the aircraft or spacecraft as a whole. The traditional approach to design is no longer adequate unless it can be supplemented by a numerical, computer-based approach in which the trade-off between conflicting design requirements can be quantified, and many more alternatives evaluated. Optimization plays an important role in this process, by providing a tool to identify the active design constraints and to steer the design towards some required goal such as minimum weight or cost. The goal of the research efforts in this area is the development of efficient and robust design and optimization tools for a variety of challenging structural design problems, which meet the needs that industry is facing.

The following topics are included in this sub-program:

• Development of design and optimization procedures for specific structural design problems; • Theoretical optimization including multi-level procedures and optimization of structural shape and layout;

87

• Tailoring of advanced fiber-reinforced composite structures; • Design and optimization of actively sensed and actuated structures. 8.2 Stability of thin-walled structures

In modern designs, which are often obtained by use of one of the structural optimization codes and which may be of new high strength materials such as advanced composites, structural response is often dictated by the stability and vibration behavior. This is due to the drive for achieving lightweight structures which result in thin-walled constructions. Such structures are sensitive to imperfections and display nonlinear response characteristics. This implies the need to investigate and understand the response characteristics of thin-walled structures under different loading conditions by carrying out extensive numerical calculation and/or experimental validation. A key issue is the development of fast and accurate analysis capabilities for thin-walled structures, incorporating all the theoretical knowledge accumulated in the last decades through intensive research in the aerospace, nuclear, and offshore fields, and making efficient use of the currently available interactive and (super-) computing facilities. Part of the ongoing thin-walled structures research is therefore concerned with the buckling, post-buckling and dynamic stability behavior of shells. The goal of the research efforts in this area is the availability of improved design criteria and the necessary analysis tools. The following topics are included in this sub-program:

• Theoretical, numerical, and experimental studies of the collapse behavior and nonlinear behavior of composite panels and shells under static and dynamic loading; • Development of an International Imperfection Data Bank and DISDECO (Delft Interactive Shell DEsign COde); • Development of efficient semi-analytical and Finite Element based tools (reduced-basis methods) for the nonlinear analysis of slender and thin-walled composite structures. 8.3 Advanced computational methods for structural and functional materials

A wide variety of challenging problems in aerospace engineering cannot be satisfactorily solved using the traditional finite element method based on Lagrange polynomials. Limitations of the traditional FEM are related to its high computational cost in complex systems and/or its inability to model relevant features in the problems. The sub-program on advanced computational methods focuses on the development of novel computational methodologies intended to address the shortcomings of the traditional FEM. One main thrust in this program pertains to the area of Isogeometric Analysis, which provides a seamless connection between objects created in CAD software and the corresponding analysis. This computational approach streamlines the design process and supports the activities in other research sub-programs. A second focus point is the development of computationally-efficient Multiscale Analysis algorithms that relate the microscopic behavior of materials and systems to their effective (macroscopic) response. Both concurrent and hierarchical multiscale approaches are used for advanced material modelling and solution of coupled problems. The following topics are included in this sub-program:

• Isogeometric analysis and design of composite turbine blades and shells • Isogeometric analysis of fluid-structure problems • Multiscale simulations of multiphase steels • Lifetime predictions of self-healing thermal barrier coatings used in aeroengines

8.4 Lightweight composite structures

Increased use of composite materials in aerospace, automobile, shipping, and civil engineering structures has revealed several areas where improved understanding of the performance of these structures under mechanical loading is required in order to decrease their weight further or tune their performance more accurately to specific requirements. Relevant requirements are frequency response, crash absorption capability, and geometric stability under thermomechanical loads. Work is continuing in the areas of damage tolerance and fatigue of composite structures. Quasi-static finite element-based modeling of impact of monolithic laminates and grid stiffened structures showed that a combination of failure criteria for fiber failure and a critical energy release rate calculation for delamination in a progressive failure model gives good accuracy in the extent and type of damage caused during low speed impact. Different models are used for the residual stiffness and strength of the damaged material. The method is extended to compression after impact and comparison with published results shows very good agreement for most quasi-isotropic laminates. The following topics are included in this sub-program:

• Use of advanced physics-based failure criteria to predict onset of failure during impact • Progressive failure with continuous updating of strength and stiffness of fibers and matrix for

impact damage and fatigue analysis • Use of failure criterion in finite element modeling of the impact event in grid-stiffened structures • Experimental verification of analytical predictions for compressive failure of composite grid-

stiffened structures with damage. • Use of degree of bonding to predict the quality of laminates produced using automated

manufacturing techniques in composites with FEM • Experimental validation of interlaminar shear strength of laminates produced using automated

tape laying 8.5 Smart structures

Smart Structures may very well lead the way to the next breakthrough and major technological advancements in aerospace. Applying smart structures to aerospace engineering requires a new way of thinking in terms of integration as well as multidisciplinarity and multifunctionality. The focus of the smart structures research at ASCM is dedicated towards solving the design challenge that is posed by smart structures because of their multidisciplinarity and multifunctionality. Furthermore research efforts are dedicated towards practical solutions for smart structures. The goal is to develop concepts starting from initial ideas all the way to proof of concept in a realistic environment like a wind tunnel of a large-scale UAV. The following topics are included in this sub-program:

• Numerical aeroelastic analysis and design of smart structures • Concept development and hardware of morphing structures • Wind tunnel experiment of smart structures • Active control and performance optimisation using smart structures

8. Short description of subprogrammes related to research school EM

8.1 Structural Optimization and Mechanics

For the case of Micro-Electrical-Mechanical Systems (MEMS) and high-tech applications, the interaction between mechanics and other domains of physics becomes critical. For mechanical problems related with engineering materials, different length scales need to be taken into account with various multi-scale approaches. Because of these aspects, the analysis of practical problems usually takes a tremendous effort. Therefore, further development of efficient, multidisciplinary, multi-scale numerical modelling techniques is required. It is also important to increase the computational efficiency of numerical techniques by smart choices of model order reduction without compromising the desired level of accuracy. These techniques should be tailored for high-performance computer architectures.

Vital to the numerical techniques aforementioned is the finite element method (FEM), which has become the de facto methodology for the analysis of problems in computational solid mechanics. The activities being developed at SOM not only make use of the FEM for solving challenging problems, but also involve developments to improve the numerical techniques themselves. In particular, finite element formulations of the Generalized/eXtended (GFEM/XFEM) type have the spotlight nowadays because of their ability to deal with complex geometries with very simple and structured finite element meshes. Decoupling the problem geometry from the mesh it is solved upon brings extra flexibility that could be exploited in the search for optimal designs.

Once numerical techniques are incorporated in a design process, for which often many intermediate designs and corresponding design sensitivities must be evaluated, the efficiency requirements are even more demanding. This holds for a design process in which

99

intermediate designs are evaluated "manually", but becomes more important for (partially) automated optimization processes. Improvement of structural optimization techniques cannot be achieved independently from new developments in Computational Mechanics. Only a close integration of structural optimization techniques and numerical analysis strategies can yield the most efficient design tools. Clearly, manufacturing constraints impose additional challenges on the optimization. Within this theme, the fundamentals for modelling, analysis, design sensitivities and optimization of structures will be developed. The focus will be on the multidisciplinary links between these aspects. Furthermore, new developments will be translated in prototype designs, ready for laboratory testing and ultimately made available for day-to-day practice. For this purpose we are collaborating with more application-oriented groups and companies.

8.2 Dynamic Behavior of Mechanical Systems

The design of current and future mechanical systems across different space/time scales becomes more challenging as new material developments, manufacturing technologies and design techniques make the systems lighter, more complex, more flexible and multi-functional. The challenge is mainly associated with the activation of nonlinearities which can give rise to a variety of phenomena that are not typical of linear systems: nonlinear modal interactions, transfers of energy from low to very high frequencies (situation which can become critical in complex micro-nano systems architectures), bifurcations, parametric multiplicative instabilities, subcritical behaviors, sub/superharmonic resonances, saturation, etc.

The aim of the Engineering Dynamics group is to develop studies addressing open problems in nonlinear dynamics with ground-breaking innovations in experimental, theoretical and numerical investigation. In particular, the goal is to put multi-scale nonlinear dynamical systems under a powerful microscope and pull as much as possible in full, three-dimensional formulations to unfold subtle behaviors, understand and frame them in unified theories and pave the way to their exploitation for enhanced mechanical designs. These are carried out by (i) developing innovative numerical codes based on reduced-order models together with analytical dynamics tools such as perturbation methods coupled with modern path following and bifurcation techniques, (ii) developing sophisticated measuring systems and experimental procedures to validate numerical codes, and observe complex dynamics.

The stated goals call for new tools or innovative modifications of existing tools to resolve the various time and space scales that can coexist in multi-scale nonlinear dynamical systems. Moreover, the nonlinear dynamical phenomenology is not simply investigated to avoid it during systems operations, but to integrally embed it into the design process so as to drastically improve controllability in new passive/active vibration systems architectures, sensitivity in sensing systems such as mass, and pressure sensing, actuability in actuator systems, and observability in damage detection systems.

8. Short description of sub programmes related to research school EM 8.1 Computational Modelling of Failure

Simulation of failure and the associated phenomenon of strain localisation for a range of materials. Activities focus on multiscale modelling techniques, improved computational procedures and the integration of experimental methods and sophisticated computational procedures.

8.2 Advanced Computational Procedures

This research topic is concerned with the development of computational models for the simulation of the behaviour of materials and structures. For this purpose accurate and robust models are made for the temporal and spatial discretization and algorithms are constructed for the efficient, accurate and robust solution of the ensuing non-linear algebraic equations.

8.3 Structural Dynamics

The development, experimental validation, and numerical implementation of prediction models of (i) ground vibration from high-speed trains and (ii) vibration of submerged flexible offshore structures in waves and currents.

8. Short description of sub programmes related to research school EM 8.1 Structural Dynamics and Control (Prof.dr.ir. A. de Boer, Prof.dr.ir. T. Tinga)

The research in this EM subprogramme is directed towards: • Structural dynamics, involving rotating components in machinery and optimisation and

actuation of vibrating structures. • Fluid-structure interaction and acoustics, with emphasis on thermal viscous wave

propagation and acousto-elastic coupling and the accompanying noise production. • Dynamics Based Maintenance, with focus on vibration based structural health monitoring

and physical model based predictive maintenance. The research of the group aims at generation of new, fundamental knowledge by combining numerical and experimental techniques. Based on this knowledge engineering tools are validated and made ready for application in key industrial problems. A characteristic feature of all themes is the innovative use of advanced numerical simulation methods in a design environment. Crucial information that is difficult or even impossible to obtain from experiments is added through numerical models. Current topics are:

• Structural Dynamics (Prof.dr.ir. A. de Boer) (1) Optimization of Dynamic Systems with emphasis on model reduction methods.

Optimization problems concerning complex structures with many design variables may entail an unacceptable computational cost. This problem can be reduced considerably with a multi-

120

level approach; a structure consisting of several components is optimized as a whole (global) as well as on component level. In the framework of the Dutch TAPAS 2 (Thermoplastic Affordable Primary Aircraft Structure) programme a fast algorithm and procedure has been developed (carried out by PhD F. Farzan Nasab) for the optimization of the stacking sequence of plies and demonstrated on an industrial problem.

(2) Rotor Dynamics and Multi body dynamics Rotating parts in machinery are sources of vibrations and can therefore affect the life time of the rotating part itself and the whole machine drastically. The tendency to optimize the functional performance of structures results in modern designs which often exhibit a minimal weight and very tight safety factors. In 2016 research has been carried out (by PhD P. Le) on performance improvement of micro-reaction wheels. This is done in collaboration with Moog Bradford and TU/e department of Applied Physics. Further in 2014 a new project has been started with the goal to develop methods to couple flexible multi body dynamics with other physical phenomena such as hydraulics and acoustics. In 2016 this research (carried out by PhD J. Schilder) focussed on the development of a new theory on multi-body dynamics with which two philosophies in multi-body dynamics are joined.

• Fluid-structure interaction (FSI) and acoustics (Prof.dr.ir. A. de Boer) (1) Viscothermal wave propagation

(2) Sound-absorbing materials.

A closely related part of the FSI research program, involves the development of methods and models concerning sound-absorbing materials. Marieke Bezemer focus on the angle dependence of the absorption coefficient for road pavement. In 2016 she validated her model for porous pavement and extended the model.

(3) Efficient analysis and measuring methods for source localisation

(4) Thermo-acoustic structural interaction

In june 2015 Farnaz Tajderi started research on the development of flat acoustic source structures driven by multiple controlled energy efficient actuators that can be used to realize a sound source capable of generating low frequency sound to be useful for sound generation and active noise control applications as the secondary source. In 2016 she focussed on efficient amplifiers for piezo electric actuators. Further she started developing models in which the electronic, mechanical and acoustic part are coupled.

• Dynamics Based Maintenance (prof.dr.ir. T. Tinga) (1) Structural Health Monitoring (SHM)

Several research projects are conducted on this topic, some of which are in collaboration with Production Technology, Prof.dr.ir. R. Akkerman (see chapter 11 ‘Production Technology’ for more details). Jason Hwang (NLR) continued his part-time PhD project, focusing on the development of performance indicators for SHM methods. Andrea Sanchez Ramirez now almost completed her strategy for wireless vibration monitoring of (rotating) systems and complete structures. Neda Mostafa started worked on developing SHM methods for railway bridges in the H2020 project DestinationRail. Hector Hernandez is working in the TTIW Wetsus Water distribution program - InnoWater. The research program of the Technological Top Institute Water, financed by the Dutch government and Dutch industry, focuses on

121

improving the water distribution networks. Hernandez focuses on ultrasonic measuring technologies to assess the degradation of a water pipe during service. A second PhD student, Mithun Chowdhury, also started on this program, aiming to develop a smart pipe which includes sensors and condition assessment algorithms. This first project is in collaboration with Production Technology, the second with the Pervasive Systems group (wireless sensors).

(2) Predictive Maintenance

In several projects predictive maintenance methods are developed, mostly focusing on a physical model based approach. By modelling the relevant failure mechanisms, monitored loads on the systems can be used to predict the time to failure and optimize the maintenance program. Filippos Amoiralis, PhD student in the Dinalog funded Maselma project, developed models for maritime systems, specifically focusing on marine diesel engines. Unfortunately, he decided to stop his PhD research early in 2016. Annemieke Meghoe continued working on similar methods predicting railway time to failure in a project funded by Strukton. And in 2016, Damian Rommel started on the WiMOS project, aiming to develop physics-based failure prediction models for off-shore wind turbines. The NWO funded SINTAS project on the impact of additive manufacturing (3D printing) on maintenance decisions and logistic processes was continued. Laura Cordova, one of the three PhD students in this project, investigates the durability and life time aspects of parts produced by different AM techniques, which is used as input for the maintenance and logistics optimization models in the other two work packages. Focus in this year has been on the effects of powder / particle properties and moisture on the apparent density of the powder bed and on the physical properties of the printed parts.

8.2 Computational and Experimental Mechanics (Prof.dr.ir. A.H. van den Boogaard)

The research in this EM subprogramme is directed towards Nonlinear Solid Mechanics. The mission of the Chair Nonlinear Solid Mechanics (NSM) is to develop and experimentally validate advanced numerical methods for the accurate simulation of nonlinear mechanical behaviour, in order to support the industrial needs for optimal and efficient methods for designing and manufacturing of parts and products. The main application area of the chair is the simulation, analysis and optimization of Material Forming Processes. Increased demands for accurate and computationally efficient simulations require that a number of topics have to be addressed: • Improved macroscopic material models Accurate constitutive equations are required in order to predict the final shape of a work piece after forming and subsequent spring back and its subsequent service properties. In particular the effect of the initial and evolving anisotropy, the changes in loading path as present in multi-stage forming processes, the strain rate dependency, the consequences of temperature changes in warm forming processes and the effects of annealing periods between successive forming steps have to be properly accounted for, including the effects of phase transformations. A project on long discontinuous fibre distribution in relation to the forming process extends the application from metals to composites. Material properties are commonly determined from uni-axial tensile experiments, but the deformation mode in forming is usually 3-dimensional and non-proportional. Therefore, constitutive models need to be able to consider arbitrary 3D loading paths. Although macroscopic

122

models are required for full-process simulations (regarding CPU-time), development of the models benefits from considering micro-structural evolution. For this purpose, microscopic models are also investigated. Examples of this approach are the projects on anelastic deformation of steel at unloading and on anisotropic damage evolution in dual phase steels. In order to validate material models under multiaxial stress state and arbitrary deformation paths, a biaxial test facility is available. The test facility allows for biaxial loading under simultaneous bi-directional shear and tension/compression of sheet material, including strain path changes and strain rate changes. • Advanced solution algorithms The focus of the sub-programme ‘solution algorithms’ is on efficiency. I.e. increase accuracy of calculations and/or reduction of calculation time. For steady-state type of processes, like rolling and extrusion, the ALE method is developed in this group, where the relevant deformation zone can be modelled in isolation of the non-deforming part of billet or product. A typical example where calculation efficiency has to be improved by orders of magnitude is the simulation of additive manufacturing. One project is currently focussing on this subject. For use in optimization or control algorithms, fast simulations are required and Reduced Order Modelling techniques are investigated. Finally, full process chain simulation requires the numerically efficient coupling of several forming stages, often with their own modelling details. • Joining, surfaces, contact and friction Similar as for material modelling, also the surface behaviour must be simulated with high accuracy. This field considers bonding and friction in relation to surface pressure, relative velocities, roughness, temperature et cetera. In a project jointly with the Surface Technology group a friction model that describes the effects of the surface topology on the micro scale in FE simulations on the macro scale was realized. The algorithm incorporating the model is applicable to full-scale automotive sheet metal forming simulations. Currently, this model is extended for use with coated steel and for use in hot stamping. In another project spot welding of press hardened boron steel is investigated. The influence of thermomechanical history in the heat affected zone on the strength is modelled in detail and subsequently transformed into a simplified model for full car-body analysis. Another project focuses on the influence of metal forming and injection moulding conditions on bonding srength between metal and polymer.

• Optimization and control When processes can be modelled accurately enough, the logical next step is to optimize processes by automatic numerical optimization. If robustness is not considered in optimization of forming processes, the resulting optimum is usually critical with respect to constraints. Arbitrary safety margins may be either insufficient or not fully exploit the full potential of the material; therefore the optimization model should include variability in the material properties, tool geometries and process conditions. A methodology for the prediction of the mean and standard deviation in sheet metal forming was developed and coupled to optimization of a process while reaching a required robustness. When tolerances are reduced, a sufficiently robust process setting cannot be found and the process must be actively controlled, based on a model of the process. This model-based control requires extremely fast predictive models, to correct deviations that are measured in-line. Current research

123

focusses on fast interpretation of process data to account for material and process scatter. In 2016 a project started on model based control, compensating tool heating during production start-up.

8. Short description of subprogrammes related to research school EM Research in the Production Technology group addresses the technical issues of new products and new processes. The group focuses on the optimisation of both the manufacturing process and the product performance. ‘Processing’ and ‘Product performance’ of lightweight materials in structural applications characterise the main research themes of the Production Technology group. In our view processing and performance can be optimised after thorough analysis and modelling in combination with a firm experimental programme. The experiments identify the operating mechanisms, establish relevant material property data for the modelling and provide data to test the accuracy of the models proposed. An integral approach is pursued, taking into account the interrelations between the geometric design, the production process and the material properties. The Thermoplastic composites Research Center TPRC, hosted by the group of Production Technology, continued to grow with additional members, leading to a gradual increase in research and number of PhD students. Furthermore, a number of PhD projects started in the course of 2016 with support from the University of Twente and TPRC in the field of flow modelling of long fiber reinforced composites in the melt phase and the effects of defects on the mechanical properties of continuous fiber reinforced laminates.

8.1 Automated Composites Manufacturing The first research theme is concerned with the cost-effective application of advanced continuous fibre reinforced composites. The breakthrough of this type of materials in various applications has

131

occurred to a smaller extent than might have been expected, mainly due to their high costs of manufacturing. Thermoplastic composites in particular have the potential to overcome these hurdles. In general, research in the PT group starts from a thorough analysis of the deformation and flow mechanisms involved during manufacturing and the modelling of these mechanisms. Design tools are developed to support the production of composite structures with modern techniques. The aim of these design tools is mostly to optimise the processing conditions in order to obtain a composite component having a prescribed shape or combination of materials properties. The current research projects in this theme are: • high precision composites moulding • tape placement • efficient wind turbine blade manufacturing • stamp forming process • automated tape winding

High Precision Composites Moulding Forming simulations are needed to shorten the development time of novel composite products. This requires better constitutive models, better characterisation techniques and dedicated model implementation. In this context, Ir. Van Ravenhorst continued the development of a circular braiding process simulation model to predict the fibre orientation and -distribution on arbitrary mandrels. He attempted to describe the non-axisymmetrical biaxial braiding process including yarn-to-yarn interaction and friction using a numerical derivative-free non-smooth non-linearly constrained non-linear optimization method. Furthermore, he included practical considerations for the ability to braid products on a given machine configuration. Within the UT-Impulse program A. Bhakta MSC has been employed in the course of 2016 in the field of compression moulding of long discontinuous fiber reinforced thermoplastic composites. He is currently studying the effect of the distribution of representative volume elements of meso-scale carbon fiber reinforced thermoplastic flakes over a flat mold. The highly local flow behaviour of the long discontinuous fiber thermoplastics makes material distribution an important parameter to estimate the stiffness of the final molded part. Tape placement Within TPRC, Ir. Kok is in his final year of his PhD research on the laser assisted fiber placement process, with a focus on the generation of porosities during in-situ consolidation of thermoplastic composites; with the aim to get a better understanding of the process to optimize the process and resulting part performance. Efficient wind turbine blade manufacturing Ir. Sybren Jansma has been developing new production techniques to produce (parts of) a single shot thermoset windmill blade tip section. This is a necessary step to introduce new concepts for splitting blades which are beneficial for large wind turbines. Moreover, he has also been investigating the methods to connect the tip section to the main part of a wind turbine blade. This research concerns detailing and testing connection types from macro to micro level. Stamp forming process Within TPRC, Ir. Slange continued his PhD research on the stamp forming of tailored blanks, looking specifically into the consolidation behavior during stamp forming of non-uniform thickness blanks produced by rapid automated lay-up with the further aim to optimise the process such that part performance increases and part weight, production scrap and costs decrease.

Automated tape winding

132

An EU funded HORIZON-2020 project “ambliFibre” has been started since September 2015. The mission of ambliFibre is to develop and validate the first model-based laser-assisted tape winding system for the manufacturing of tubular thermoplastic FRP parts. Two PhD students started in 2016. Production Technology is leading the Work Package 3 in which multi-physics based numerical process models will be developed for inline automated process control and virtual simulations of the laser assisted tape winding process of thermoplastic composites. In this context, a global simulation model is developed by S.M.A. Hosseini Msc. The integral virtual tool includes not only the kinematics of the process but also the optical and thermal phenomena. The output of the model can be used to determine the process ability and process settings up front, preventing time and material intensive prototyping on a trial-and-error base. The other PhD student, A. Zaami MSc is looking specifically into the process simulation and physics-based modeling for inline monitoring purposes. The final aim of the PhD is to optimize the process parameters to get higher quality products with less amount of waste.

8.2 Performance of Advanced Materials The second research theme involves a better understanding of the mechanics of new materials, focusing on the physical properties of the component and taking into account the production process used. An broad range of properties is being considered, from thermo-mechanical properties such as stiffness and structural integrity on the short and the long term. The current research projects in this theme are: • recycling of thermoplastic composites • friction surface cladding of light metals • thermoplastic composite joints • sustainable materials • energy storage in flywheels • long term performance of composites

Recycling of thermoplastic composites Guillaume Vincent continued working at TPRC on the recycling of thermoplastic composites, for which the complete recycling route is studied: 1. shredding and 2. re-manufacturing using processes similar to those for long fibre thermoplastic. In 2016, he initially focused on understanding the shredding process of industrial waste. The mixing step, which melts the matrix and disperses the fibres to form a homogeneous charge, was studied later.

Friction Surface Cladding Friction surface cladding (FSC) is a solid state process to deposit thin metallic layers on substrates. It was primarily developed to improve the corrosion resistance of the workpiece surface. It has been studied thoroughly by S. Liu MSc who defended her PhD thesis successfully at the end of 2016. The thesis covers both analytical and experimental work and includes a process window determination of this relatively new cladding process. The main objectives of the work were to understand the role of the main process parameters and to develop a simplified analytical model for the heat and pressure generation during deposition. The cladding process can also be extended to additive manufacturing like 3D printing in the solid state, as currently studied by MSc. I. Yussof. Thermoplastic Composite Joints Within TPRC, Sacchetti continued his PhD research on the characterization of the interlaminar fracture toughness of fusion bonded joints. The effects of degree of crystallinity, weave pattern and bond line architecture on the interlaminar fracture toughness of fusion bonded joints were investigated. The aim is to get a deeper understanding of the mechanism that governs the interlaminar fracture toughness of fusion bonded joints.

133

Sustainable materials Within TPRC, M.I. Rasheed MSc has finalized his PhD thesis on compression molding of chopped woven semipreg flakes and successfully defended his thesis in the course of 2016. The work focused on the processability of the material looking on to avoiding of mechanical jamming during flow and filling of ribs, and on the statistical nature of the tensile strength of the material. A technology demonstrator part was successfully molded with the findings from the work and it attracted a JEC 2016 innovation award in Atlanta, USA. Energy storage in flywheels Within UT, Dr. M.I. Rasheed is carrying out a study on energy storage in high speed flywheel systems, looking on to the aspects of improving its performance multiple folds. The aim is to find the prospects to be explored academically and industrially in a decades time; in a direction towards full utilization of the high performance material and to improve the reliability of the high speed system. Long-term performance of composites In structural applications, the ability to predict the long-term performance of composite components is imperative. In 2015, Leon Govaert joined the PT chair as professor with special appointment to strengthen the research activities on this subject. Ozan Erartsin started in 2016 as a PhD student on an experimental/numerical study on the role of the thermoplastic matrix in long-term off-axis failure of unidirectional composites. His work is aimed at clarifying the role of different failure processes in time-dependent failure of continuous fiber-reinforced thermoplastic composites and developing novel experimental and modeling methods for fast and accurate lifetime estimation. Preliminary work has focused on time-dependent failure of unidirectional laminates with a loading angle of 90° on limited number of material systems. In the future, the work will be extended to other off-axis loading angles, various material systems, and multidirectional laminates.

All activities within the programme are related to the research theme “Computational and Experimental Mechanics”.

8. Short description of sub programmes related to research school EM

8.1 Multiscale simulation techniques The discrete element method (DEM) is used extensively for the simulation of granular materials and in powder technology. Averaging or coarse-graining (CG) techniques, also referred to as the micro–macro transition, are applied to the particle data from DEM simulations to extract bulk continuum fields such as density, velocity and stress, which are important for the design of a great majority of engineering applications. The major aim of this work is to answer the question about temporal and spatial averaging scales, and what is their influence on the micro–macro projected continuum fields. Those scales often vary between different engineering processes. The final goal is to enhance the way of coupling between particle and continuum methods for multi-scale modeling, not only relying on a future increase of available computing power, but also keeping massive parallelization in mind. At the same time, hierarchical hash tables and multilevel grids for efficient simulation of poly-disperse systems and FEM/DEM coupling for fluid particle interaction problems, e.g., porous media, fluidized beds, or others, are being developed in the MSM group.

8.2 Bridging the gap between particulate systems and continuum theory

Particulate systems can be found in our daily life, such as sand on the beach, or food (cocoa powder, cereal) in the kitchen. They are everywhere in nature and constitute over 75% of all raw material in industry. The particles in these materials interact and move with respect to each other, which leads to unpredictable segregation phenomena - like in cereal, where the large pieces float on the top. Sometimes this also leads to fatal phenomena like landslides or snow-avalanches, which must be avoided or at least predicted. These particles can only be understood and predicted by using modern particle models and computer simulations, but continuum theory is used in engineering and design for almost all applications, because there are too many particles involved. Therefore, both pictures have to be combined and the gap between them has to be bridged in order to avoid problems, improve safety and enhance many the products we use every day. This VICI project ended in April 2016. Great results have been achieved on the challenge of bridging the gap between particles and continuous systems – where especially, stochastic and mesoscale methods are essential pillars supporting the bridge beyond classical continuum theories.

8.3 Wave propagation applied to gas/oil exploration, production, and processing

The project goal is to apply advanced computational science tools to predict flow, permeability, and nonlinear wave propagation through gas/oil-reservoirs to enhance efficient exploration, evaluation, and production – as well as energy efficient processing and storage. The multi-scale approach starts at the disordered grain/particle/porous-structure scale, cross-couples the high-pressure multi-phase fluid thermochemistry and -mechanics, and targets at the larger, seismic/reservoir length-scales. As motivation, in underground exploration of energy-related resources, only low frequency modes are visible, i.e. small length scales disturb transport and wave propagation. The challenge is to model this multi-scale problem, which requires innovation in computational science for understanding and interpreting non-linear wave-propagation. As novel system, mixtures of large/small particles are now complemented also by mixtures of hard/soft (e.g., glass/rubber) particles with wide application perspectives.

8.4 Multiscale Analysis of Particle Processes Despite their significance, many industrial particulate processes display unpredictable behaviour due to both their multiscale nature and the coexistence of different phases: this leads to undesirable losses in resources, energy, money and time. Considerable progress can be achieved using multiscale analysis and modelling to provide both visual and quantitative details of the dynamics of multiphase particulate systems. However, immature predictive capabilities, together with a lack of expertise and education in this developing field, hinder the adoption of these technologies. In order to address this skills gap, a new EU-ITN network, T-MAPPP, brings together 15 leading European organizations in their respective fields, including 10 industrial companies and stakeholders ranging from agriculture/food processing, consumer/personal care, chemicals/pharmaceuticals to software and equipment manufacture, to foster and develop a pool of ESRs and ERs who can transform multiscale analysis and modelling from an exciting scientific tool into a widely adopted industrial method.

8.4.1 Constitutive modeling of (adhesive) anisotropic granular solids Dense granular materials behave differently from fluids or solids. Classical continuum theories fail in describing granular matter when the onset of flowing is approached, and his properties, as dilatancy, yield limit, anisotropy and ratcheting. In fact, the behavior at macro-scale is strongly related to smaller-scale field variables and kinetic processes. The goal is to solve this lack with a multiscale approach, coupling discrete and continuum. Getting insights from Discrete Element Method (DEM) simulations a continuum in-homogeneous model will be developed and implemented to describe the macroscopic behavior of the material in terms of homogeneous local properties. A first step is the development of a local constitutive model with anisotropy. The model involves only scalar quantities and as new ingredient anisotropic moduli. As opposed to isotropic materials, shear strain can cause, e.g., dilation and hence compressive stresses, when anisotropy is considered. The local field variables are expressed in terms of material parameters, measured by DEM simulations, leading to a complete calibration of the predictive model, when also an isotropic state variable for the packing efficiency is considered.

8.5 Shaping segregation: Continuum modeling of segregation in particulate systems Dense, dry granular avalanches are very efficient at sorting the larger particles towards the free surface of the flow, and finer grains towards the base, through the combined processes of kinetic sieving and squeeze expulsion. Main aim is to develop a unified continuum model of particle segregation, capable of simulating realistic particles and complex system geometries. The model will be able to handle polydisperse flows of irregularly shaped particles with evolving size-distributions. Hence, it will even be possible to predict the behaviour of systems in which the fragmentation/agglomeration of particles occurs. The focus of this research is now on using this model to explain phenomena caused by segregation. These include pattern formation in rotation drums, levee formation in geophysical flows, particle size structure of a flowing finite mass of material in avalanches and axial segregation in long rotating cylinders. The proposed approach involves a powerful combination of particle simulations (S), experimental (E) techniques and continuum modelling (M), producing both theoretical and numerical solutions. The continuum numerical codes will be implemented in the open-source software package oomph-lib (http://oomphlib.org) while the particle simulation codes will be implemented in MercuryDPM (http://MercuryDPM.org). These codes are freely available to both academia and industry via public releases. In 2015, the spin-off company MercuryLab

(http://www.MercuryLab.org) has been launched, focusing on training and consultancy for DEM simulations and MercuryDPM.

8.6 Modelling of sintering in particulate materials In most realistic situations, where particles come in contact, it can NOT be assumed that the contact properties are independent of pressure, temperature or time. Therefore, this project studies pressure-, temperature-, and time-dependent contact properties and their influence on the macroscopic powder flow behavior. Sintering is chosen as a particularly relevant application and starting point, where all these phenomena are relevant. The goal of this project is to model the sintering particles in contact, before the particles lose their identity. For this, temperature- and pressure-dependent contact models have to be developed in parallel to contact-force measurements (with Kappl/Fuchs, Mainz). The many-particle simulations will then be adapted to the materials used and experimentally validated (Tomas+, Magdeburg; Antonyuk Kaiserslautern). As the result of the project, a verified numerical model for the sintering process of many particles will become available. This will then be used for the micro-macro transition in order to obtain better theoretical constitutive relations for a macroscopic description based on the contact-mechanics and -physics. Most recently, this study has been applied to additive manufacturing processes.

8.7 Micromechanical modeling of asphalt Asphalt is an important road paving material. Besides an acceptable price, durability, surface conditions (like roughening and evenness), age-, weather- and traffic-induced failures and degradation are relevant aspects. In the professional road engineering branch, empirical models are used to describe the mechanical behaviour of the material and to address large-scale problems for road distress phenomena like rutting, ravelling, cracking and roughness and phenomena like paving and compaction. The meso-scopic granular nature of asphalt and the chemistry and mechanics of the bitumen layer between the particles is only partly involved in this approach. The discrete particle method is a modern tool that (first of all) allows for arbitrary (self-)organization of the asphalt meso-structure and for rearrangements due to compaction and cyclic loading. This is of utmost importance for asphalt during the construction phase and the usage period, in forecasting the relevant distress phenomena and understand their origin on the grain-, contact-, or molecular scales. The ultimate goal is to derive micro- and meso-based constitutive models that can be applied to model asphalt pavements on the larger (macro) scales. Special focuses are the heat-induced self-healing processes into the mixture and the development of Warm (low temperature) Mixture, by using proper fluidization additives.
