WELCOME

Dear colleagues,

ECF19 in Kazan has not only been a successful conference but continues to be productive with respect to Special Issues of Engineering Failure Analysis, Engineering Fracture Mechanics and International Journal of Fatigue. The conference organisers plan five of them, and submission of manuscripts has started. As the number of Special Issues determines Elsevier’s honorarium to ESIS, we depend on the commitment of our members to initiate these publications as an outcome of conferences and workshops organised by ESIS. As you can see in the table below, this has been done with great success over the last years, and we, the ESIS ExCo, thank all the guest editors for their valuable work.

I decided to publish an agreement between ASTM E08 and ESIS of 2001 for cosponsoring conferences as I found that its text was widely unknown.

Due to other obligations over the last months, I have been a little lazy with my blogs on www.imechanica.org/blog/23810be continued, of course, but as they are meant for promoting scientific discussions I also would like to once again encourage all readers and in particular the authors of the addressed papers to contribute their comments. Science lives from dialogue and scientific activities do not cease in producing a maximum number of publications.

Background

Time and financial constraints often require accelerated testing methods to generate data for design, lifing or remnant life purposes. Although beneficial in terms of time and money the data extrapolation and metallurgical conseqaccelerated testing are always subject to debate.

This workshop aims to address these issues by looking at methods used to accelerate tests, considering ways that the data can be used predict how components will behave or continue to behave in service and by determining the effect accelerated conditions have on the microstructures of tested materials.

Topics

It is intended that the majority of presenters will be invited speakers, but if you wish to contribute a presentation or display a technical poster please notify Dr Peter Barnard, [email protected] .

� Accelerated Testing Methods

o Use of accelerated environments, e.g. higher stress, higher temperature, reduced time per cycle but more frequent cycles and more concentrated corrosive atmospheres.

o Use of small scale samples for remnant life estimates which are often not included in existing testing standards.

� Data Assessment Procedures

o Data extrapolation techniques to predict long term data; limits of extrapolation.

o Use of small scale data sets to define inspection intervals.

o Predicting failure mode regimes, e.g. changes in slip planes under accelerated creep.

� Metallurgical Consequences of Accelerated Testing

o Microstructural issues, e.g. phase stability at test temperatures, grain growth, growth or dissolution of strengthening precipitates.

o Changes in incubation times, e.g. breakaway oxidation, change in the corrosion mechanism.

o Sensitization issues, e.g. temper embrittlement.

o Change in damage mechanism

The European Structural Integrity Society (ESIS) is generally comprised of over 500 members each year. There are individual members, as well as members who join through their home countries of which there are over 20. ESIS has a Council and an Executive Committee (ExCo). The ExCo meets periodically to assure the smooth running of ESIS and present new ideas for approval at the Council which meets every two years. The Council is made up of delegates from representative countries that have at least 10 membTechnical Committee (TC) Chairs, as well as ESIS postand Vice Presidents. Every two years, ESIS sponsors the European Conference on Fracture (ECF). In addition, TCs run small conferences and workshops on specific Following ECF and TC meetings, Special Issues are published in three Elsevier journals: Engineering Failure Analysis, Engineering Fracture Mechanics and International Journal of Fatigue.

1. Introduction

I have been asked to report on the European Structural Integrity Society (ESIS) at the Engineering Structural Integrity Assessment Conference (ESIS12) which took place on May 28 and 29, 2013 and was sponsored by the UK Forum for Engineering Structural Integrity (FESI).

The European Fracture Group (EFG) which had its beginnings in about 1971 in France, is the forerunner to ESIS. EFG held its first meeting in Compiegne, France in 1976 which was organized by Professor Dominique Françios. There followed meetings every two yeaunderwent a name change between 1990 and 1992 to ESIS. The early history of EFG and ESIS may be found in Milne [1] and François [2]. Professors Firrao, François and Pineau, who were present in the early days of EFG and continue to be members of ESIS shared with me their memories of EFG and ESIS (Firrao [3], François [4] and Pineau [5]).

In Section 2, a list of the ECF conferences are presented. Each is a major ESIS event. In addition, to the invited and contributed lectures, of late there are poster sessions and interesting cultural events. The TCs are described in Section 3 which constitute an important component of ESIS activities. As a result of ECF conferences and TC conferences and meetings, Special Issues are published in three Elsevier journals which are supported by ESIS. Recent Special Issues are described in Section 4. Recently, ESIS began a blog in which papers from Engineering Fracture Mechanics are reviewed. This is also discussed in Section 4. ESIS Award recipients and Fellows

The European Structural Integrity Society (ESIS) is generally comprised of over 500 members each year. There are individual members, as well as members who join through their home countries of which there are over 20. ESIS has a Council and an Executive Committee (ExCo). The ExCo meets periodically to assure the smooth running of ESIS and present new ideas for approval at the Council which meets every two years. The Council is made up of delegates from representative countries that have at least 10 members,

holders that include the President and Vice Presidents. Every two years, ESIS sponsors the European Conference on Fracture (ECF). In addition, TCs run small conferences and workshops on specific subjects. Following ECF and TC meetings, Special Issues are published in three Elsevier journals: Engineering Failure Analysis, Engineering Fracture Mechanics and International Journal of

3. ESIS Technical Committees

ESIS currently has 12 Technical Committees (TCs) as described below:

TC1 Elastic Plastic Fracture Mechanics, Professor Uwe Zerbst (Germany), Chairman. A major topic in the past was the devfracture mechanics test procedures (ESIS P1 and ESIS P2) with specific emphasis on elastoplastic, R-curve behavior. This task has essentially been completed. Attention is being turned to component assessment and implementation of fracture andmechanics methods. Component integrity assessment may be based on the prevention of crack initiation and extension, as well as on the prevention of final fracture. The choice of the assessment methodology in a specific case depends on multiple factors such as the materials involved, design philosophies such as safe life, fail safe or damage tolerance and restrictions in practical implementation.

TC2 Micromechanisms, Professor Jaroslav Pokluda (Czech Republic), Chairman, Professor Otmar Kolednik (Austria), Vice Chairman. a period of inactivity, this committee was reestablished by Professor Jaroslav Pokluda in 2006. Since then, it has organized eight workshops in various European countries; the

last one in Oxford was coBased upon these meetings, several special issues in Engineering Fracture Mechanics have been produced. On average, there have been 50 participants at TC2 meetings focusing primarily on the relationship between microstructure and resistance to crack propagation. Recently, there has been growing interest in multi-scale models of deformation and fracture processes. It may be noted, furthermore, that beginning in 2011, the participation of young scientists, particularly from developing countries, has been by TC2 resources related to the production of special issues.

TC3 Fatigue of Engineering Materials and Structures, Professors Andrea Carpinteri (Italy) and Les Pook (UK), Co-Chairs, Andrea Spagnoli (Italy), Secretary. Since 2000, this TC has beeco-chaired by Professors Andrea Carpinteri and Les Pook. Its main activity is to disseminate the substantial international progress achieved in fatigue and fracture mechanics research, and to illustrate how to apply these results in industrial practice with a view to closing the gap between design and manufacturing. To achieve these objectives TC3 organizes small niche conferences that bring together scientists and engineers from around the world. It holds a Crack Paths (CP) conference in Italy every tyears (since 2003, Parma, Italy). The fifth in the series will be held in Ferrara, Italy in 2015. Furthermore, it holds an International Multiaxial Fatigue and Fracture (ICMFF) conference every three years (since 1982, San Francisco, USA). The tenth in the series will be held in Kyoto, Japan in 2013, and the eleventh in the series will be held in Seville, Spain in 2016. In addition to the publication of conference proceedings on a CD, special issues in the ESIS affiliated journals containing extended versions of selected papers are published. Despite increased efforts in the understanding of the crack path process and multiaxial fatigue and fracture behavior, failure assessment procedures are becoming more and more complex. Therefore, a regular revprogress via a committee that includes experimentalists, theoreticians, industrial practitioners and academic experts is essential.

controlled during this test, and it is assumed that the stress amplitude σa remains constant. However, for many cyclically unstable materials such as polymers, composites and some metallic alloys, σa changes considerably causing imprecision in the fatigue characteristics of material in terms of Wa and Nf. Thus, a moreprecise and direct determination of the energycharacteristics becomes an important task for an energy-based approach to multiaxial fatigue. Other areas of interest include progress of the spectral method for fatigue life assessment for materials under multiaxial random loading in the frequency domain; improvement of failure prediction by means of fatigue damage maps for machine components and structures subjected to multiaxial service loading by calculations using FEM or BEM with spectral methods; development of mechatronic systems of uniaxial and biaxial strength machines controlled by the strain energy density.

TC4 Polymers and Polymer Composites, Professors J. Gordon Williams (UK) and Andrea Pavan (Italy), Co-Chairs, Professor Bamber Blackman (UK), Secretary. This TC has been in existence for more than thirty years. It meets every six months in Les Diablerets, Swand holds a conference in the same village every three years. The seventh in the series will be held in 2014. TC4s main activity is the development of fracture mechanics based standards for polymers, composites and adhesives by the members who eround-robin testing exercises to develop protocols which are then submitted to ISO to be adopted as standards. A recent development is a round-robin on the computation of mixed mode fracture in composites and adhesive joints. This is a good examexperimental activity has generated a computing issue which requires resolution. The enthusiasm and good will in the committee has enabled it to flourish for such a long period and to do valuable work.

TC5 Fracture Dynamics, Professor Hugh MacGillivray (UK), Chairman, Professor Gyongyver Lenkey (Hungary) and Dr. Uwe Mayer (Germany), Co-Vice-Chairs. The main achievements over 20 odd years include: BS 7448 -3 on rapid load fracture; ISO 14556 on Instrumented Charpy V and sub-size Charpy V including several round-robins; close cooperation with ASTM in introducing equivalent US instrumented Charpy standards; highround tensile round-robins and test document (now being included in a new ISO standard); high rate sheet tensile round-robin and tesdocument (now being included in a new ISO standard); impact compression, second roundrobin between three laboratories completed in 2012, test document in progress; ESIS 20 published workshop proceedings Evaluating Material Properties by Dynamic Testing,Walle ed.

The next one will be in 2013 in Smolenice, Slovak Republic with a title “Fractography of Advanced Ceramics”.

TC8 Numerical Methods, Professor Huang Yuan (Germany), Chairman. TC8 are working on numerical methods, as well as new modeling methods of material damage under different loading conditions. The next action is to start a roundzone modeling for fracture and fatigue crack propagation. As a result of the absence of suitable experimental data, the action has been delayed. Experimental data is now available and will be issued to TC members iweeks. In the past three years, TC8 has organized an annual meeting in Wuppertal, Paris and Berlin. In July 2013, the annual meeting will take place; the location is not yet defined.

TC9 Concrete, Professor Giuseppe Ferro (Italy), Chairman. TC9 is preparing to consider the application of nanotechnology for increasing the mechanical performance of cementitious materials. In particular, attention will be paid to reinforcement by using Carbon Nanotubes for increasing strength and fracture energy. Another related topic is the use of nanoinerts obtained from carbonization of different materials in order to extend the particle size curve toward sub-micro scale. This will permit an increment in both the strength, as well as the toughness of the material, whereas high performance concretes obtained by adding silica fume appear to be very brittle.

has always been strongly related to the development of fracture mechanics test and evaluation techniques and their application to problems of EAC, with the main emphasis on monotonic loading (i.e. stress corrosion cracking). In the past, the work of TC10 was focused on the development of innovative methods for testing of EAC and on the elaboration of fracture control guidelines for controlling EAC. The work was supported by the European Commission through grants for two research projects which involved more than 30 European laboratories and research groups and led to the introduction of a new ISO standard on accelerated EAC testing.

Knowledge Management in the area of environmental degradation of metallic materials and the solution of complex technical problems are new challenges, and the participation in existing networks such as technical associations and Working Parties (Communities of Practice) and the formation of new networks will play an important role in the future. One example is the “Mediterranean Network on Corrosion and Integrity” initiated by TC10 and aimed at connecting scientists and engineers with expertise in corrosion, environmentally assisted cracking and material science to support industry needs in the Mediterranean countries.

TC10.1 Subcommittee on Hydrogen Degradation, Professor Hryhoriy M. Nykyforchyn (Ukraine), Chairman. This Subcommittee was founded in 1995 following an initiative of members of the Karpenko PhysicoInstitute of the National Academy of Sciences of Ukraine. Since then, the TC 10 Committee and the TC10.1 Subcommittee have jointly organised a number of successful technical meetings and workshops with contributions typically addressing material properties under environmental degradation; inspection and control; risk assessment; damage mechanisms and their prevention; as well as, corrosion management.

TC11 High Temperature Mechanical Testing, Dr Hellmuth Klingelhöffer (Germany), Chairman, Mr. Larry Candler (UK), Vice-Chairman, Dr. Peter Barnard (UK), Treasurer, Mr. Malcolm Loveday (UK), Secretary. This TC has been in existence for more than 30 years. The committee works on engineering problems and challenges in high temperature mechanical testing. The main committee consists of approximately twenty European experts. Committee meetings are normally held twice a year in the UK. There are also working groups which consist of: temperature measurement (drift of thermocouples, round-robin for thermocouple calibration); crack growth measurement; and non-standard testing.

Several committee members also work in national and international standard committees to ihigh temperature testing techniques. For more information see www.htmtc.com.

TC12 Probabilistic Interpretation of Mechanical Property Data, (UK), Chairman, Dr. P.L. Windle (UK), Secretary. Past activities in this area include examine failure data generated by fracture toughness, tensile, fatigue and creep testing for both metallic and non-metallic materials. This was combined with presentations on physical mechanisms involved in deformation, fracture and modeling of these processes. The structure of test data was discussed in relation to building probability models and presentations made on implementation of this approach. In addition, training seminars were held about probability modeling. TC 12 applied to the Ecommission for funding under one of the frameworks but the application was not successful. Following retirement of some of the key participants, the activities of TC12 have declined.

TC24 Integrity of Railway Structures, Professors Stefano BerettThe problems of the early days of railway technology were overcome long ago. However, more recent innovations, such as hightraffic and higher axle loads, have given rise to new challenges regarding almost every railway component. In order to avoid incalculable risks, the application of damage tolerance concepts based on fracture mechanics is increasingly becoming an essential aspect of structural integrity of rails as well as of rolling stock. TC24 was established in 2004 undeProfessor Karl-Heinz Schwalbe, after an initial series of successful meetings. From 2006 to 2010, the chairmen were then Professors Roderick Smith and Prof. Uwe Zerbst. From 2010 until 2013, the chairmen were Professors Stefano Beretta and Roderick Smith. TC24 has organized a series of successful workshops and meetings, which have led to the preparation of three Special Issues: Application of Fracture Mechanics to Railway Components, edited by U. Zerbst and K. Madler, Mechanics, Vol. 72 (2005); Fatigue and Damage Tolerance of Railway Rails, edited by U. Zerbst, R. Heyder and L.

ENVIRONMENTALLY ASSISTED DEGRADATION OF THE PHYSICAL AND MECHANICAL PROPERTIES OF LONG

Karpenko Physico-Mechanical Institute of the National Academy of Sciences of Ukraine

INTRODUCTION

Loss of integrity of long-term exploited structures is usually caused by the development of macrocracks, which is considered in the frame of fracture mechanics approaches. Therefore structural materials, including steels, are chosen on a stage of design with sufficient level of crack initiation and propagation resistance in operating conditions. However the main relevant physical and mechanical properties, which are taking into consideration on the stage of design, worsen often during the operation. Such indegradation (degradation of properties) increases a risk of structure integrity loss.

The in-service degradation of mechanical, corrosion and corrosion-mechanical properties of structural steels operating in corrosive environments is considered in the paper under an angle of a role of corrosion-environments in the process of degradation. Investigations were carried out in the Department of Corrosion-Hydrogen Degradation and Materials Protection of Karpenko PhysicoMechanical Institute and based on a comparison of materials in as-received state and after service. Two types of steels are considered here: high temperature steels for power plants and steels for main oil and gas pipelines.

The problem of in-service material degradation has many topics. Besides of the general degradation laws following topics are important: susceptibility of material properties to the degradation, environmental effects on the in-bulk material degradation, degradation mechanisms, in-laboratory modelling of degradation, NDT of material degradation.

GENERAL DEGRADATION LAWS

In Figure 1 the general laws of indegradation mechanical properties of structural steels [1–8] are shown. Usually indegradation of steels operated at ambient temperature is related to with the process of deformation aging (the stage I). At etemperatures the degradation is caused by diffusion. On one hand the stage of deformation aging causes an increase of the strength and hardness. On the other hand it results in

At elevated temperatures the degradation is caused by diffusion. On one hand the stage of deformation aging causes an increase of the strength and hardness. On the other hand it results in

decrease of plasticity and the brittle fracture toughness.

The stage II is the stage of dissipated damaging, which is more dangerous in respect to the loss of integrity. At the high level it is accompanied by worse mechanical behaviour of metal: a) decreased strength and hardness as well as reduced brittle fracture toughness;increased elongation at a decrease crossarea; c) the deflection from the straight line on stress-strain curve may be caused not by the beginning of macroplastic deformation but due the compliance increase caused by dissipated damaging.

Fig.1 Two principal stages of indegradation: I – stage of deformation aging; II – stage of dissipated damaging.

SUSCEPTIBILITY OF THE MECHANICAL PROPERTIES TO IN-SERVICEDEGRADATION

The most important result of the inmaterial degradation is a reduction of brittle fracture toughness. Therefore test conditions that cause embrittlement provide a better comparison of relevant mechanical properties of steels in as-received state vstate. These are tests of specimens with notches or cracks, under impact loading, at low temperatures, in corrosion environments either after preliminary hydrogenation or during the hydrogenation.

Fracture mechanics parameters are more sensitive than KCV, but it is possible to increase the sensitivity of KCV tests by using the crack propagation energy instead of the total energy of fracture [8].

From the other hand, a sensitivity of exploited steels to hydrogen embrittlement increases also, therefore, for the evaluation of its in-service degradation is preferable the hydrogenation conditions, best of all crack growth resistance under action of hydrogenating environment.

A ROLE OF WORKING ENVIRONMENTS INBULK MATERIAL DEGRADATION

Investigations of the mechanical properties of the top and bottom areas of the oil and gas pipelines showed that the metal mechanical properties of the bottom areas are worse due to stronger corrosion damage of the inner surface. It means that the water condensed from transported product is not only corrosively aggressive but may also cause material hydrogenation, which is an electrochemical interaction between metal and aqueous environment being a hydrogen source.

Figure 3 shows in specimens of in-service main gas pipelinwere cut close to the external or internal surface. These results prove that the changes of the material properties occur due to the contact with transported product [9].

MECHANISM OF IN-BULK MATERIAL DEGRADATION

Despite of common features, the meof steel degradation is usually distinquished between those at ambient temperature and those at elevated temperature. In the last case the dissolution of martensite with intensive diffusion causes a reduction of pearlite and carbide formation at grain boundary in carbon and low-alloyed steels. These are the main reasons for simultaneous drop of the hardness and strength one hand, and the brittle fracture toughness on the other hand.

According to the widespread opinion, the principal cause of degradapipelines steels is the deformation aging, which occurs when free carbon migrates to dislocations, settles there and decreases its moveability. The role of free carbon consists also in its moving by diffusion from grain bodies to grain boundaries. Since this process is very slow at ambient temperature it is considered [10] that during decades of pipeline operation carbon can make only 1 µm in direction to grain boundaries, but this is sufficient to create there nano-sized carbides (Fig. 4).that hydrogen can intensify carbon migration by accelerating diffusion [11, 12]not only facilitates crack initiation and propagation but also changes material microstructure.

BULK MATERIAL

Despite of common features, the mechanism of steel degradation is usually distinquished between those at ambient temperature and those at elevated temperature. In the last case the dissolution of martensite with intensive diffusion causes a reduction of pearlite and

ain boundary in carbon alloyed steels. These are the main

reasons for simultaneous drop of the hardness and strength one hand, and the brittle fracture toughness on the other hand.

According to the widespread opinion, the principal cause of degradation of the main pipelines steels is the deformation aging, which occurs when free carbon migrates to dislocations, settles there and decreases its moveability. The role of free carbon consists also in its moving by diffusion from grain bodies to

ndaries. Since this process is very slow at ambient temperature it is considered [10] that during decades of pipeline operation carbon can make only 1 µm in direction to grain boundaries, but this is sufficient to create there

sized carbides (Fig. 4). It should be noted that hydrogen can intensify carbon migration by

[11, 12]. Thus hydrogen not only facilitates crack initiation and propagation but also changes material

Fig. 4 The model representing the mechanism of in-service degradation of main pipeline steels

The opinion that the material microdamage is the main cause of the degradation of pipelines is consistent with the results of the investigations of hydrogen behaviour in metal obtained by assessing the hydrogen permeability and temperature dependent hydrogen extraction from the steels in different states [1, 3, 13]. These two parameters are very sensitive to defects, which are considered as hydrogen traps and serve as the base of the defectiveness analysis. The physical (lattice) and effective D* (with regard to trapping) diffusion hydrogen coefficients can be determined and the ratio D/D* = 1 + N(kcalculated. Here N is the density of traps, are the kinetic constants of trapping and release of hydrogen from traps, and N(efficiency of hydrogen trapping. determination of hydrogen amount in the metal by vacuum extraction with stepwise temperature increase it is posible to a relatively low temperature, “lowhydrogen, i.e., hydrogen located in lowtraps (dislocations), and “highhydrogen located in “deeper” traps (pores, nano-, or microcracks), which leaves such defects at higher temperatures. As it was shown, long-term service of steels causes a decrease of effective diffusion hydrogen coefficient and shifts a temperature, at which the most part of hydrogen lefts metal, in direction to “high-energy” hydrogen.

In-service decrease of grain boudary strength is in agreement with the study of internal friction of the gas pipeline steels X52 in as-received state and after 30 years of service [3]: the observed rise of peaks in the range at 600 – 1050 K indicates about a hampering of relaxation processes on grain (between phases) boundaries due formation there defects.

MATERIAL DEGRADATION AT PIPE WELD

The material degradation rate in welds is different in different zones. Therefore it is

important to find out which zone is the most sensitive to in-service changes. For example, while it is generally acknowledged that the heat effective zone has particularly low brittle fracture toughness and hydrogen embrittlement resistance, it was find out that the steam pipeline weld material is more sensitive to inservice degradation than the basic material [14]. It means that the weld metal and not the heat affective zone can limit the lifetime of pipelines.

It is generally acknowledged that the corrosion process different weld zones depends not only on the material properties in this zone but also on the properties of the neighbordue to the effect of galvanic couples. Then inservice change of the electrochemical parameters, i.e. The electrode potential, at different rates for different zones can cause a change of polarity of weld zone (fig. 5). Not only the anodic part in a galvanic couple is dangerous because of additional metal dissolution in this zone but also the cathodic part, where the material hydrogenation can occur. Since after the long term operation the material becomes sensitive to hydrogen embrittlement, this efcan be more important than the increased anodic dissolution.

APPLICATION OF ELECTROCHEMISTRY APPROACHES FOR THE PREDICTION OF MECHANICAL PROPERTIES DEGRADATION

Since a long-term operation alters not only the mechanical properties but also the electrochemical parameters, it was proposed to include this effect for the prediction of indegradation of the material state [The electrochemical properties can be measured in field conditions in a nonTherefore this approach can be considered as non-destructive testing. Figure 6 demonstrates a good agreement between the mechanical (impact strength) and the electrochemical (polarisation resistance) parameters, both having high sensitivity to the material degradation.

It should be noted that the operation in corrosion environments does not necessarily mean that it can be used as an electrolyte for the prediction of mechanical properties degradation. The service environment is interesting from the point of its role in degradation process, but it may be not the best for the mentioned goal. Therefore a model environment was developed that minimizes formation of protective films on the material surface and increases this way the sensitivity of electrochemical parameters to changes of material state (Fig. 6b).

The known method consists in the prestraining of specimens up to 10% with the subsequent heating to 250hour during this temperature (USSR Standard GOST 7268-82). This detects the possible process of deformation aging, even during hot covering of pipeline by isolative coating. However the fact that the microdamage of longterm operating steels is the main cause of their in-service degradation should be taken into account. The proposed method consists in: preliminary hydrogenation of specimen by electrolytic charging; electrolytic coating of specimens with copper for hydrogen desorption prevention; holding of specimen up to 30 days under static loads that correspond to the service

Figure 7 shows the effectiveness of the proposed method on the example of evaluation of material state, using the elongation δ as plasticity parameter. As it was mentioned above, the elongation decrease does not occur during the whole test period (like the reduction of cross-section area does) because of the inmaterial dissipated damaging (Fig. 7a). The conventional method provides a monotonic decrease of δ (Fig. 7b), while the proposed method give a non-monotonic decrease (Fig. 7c), which agrees with the test data on steels after different times of operation (Fig. 7a). Since such special dependence of elongation on the operation time is caused by dissipated damaging, it means that with the proposed method, which uses hydrogenation of material, the material degradation in service conditions is well reproduced.
