“MacroModelMat” (M3) - Macro-level predictive modeling, design & optimization of advanced lightweight material

systems

http://www.sim-flanders.be/

Targeted breakthroughs and progress beyond the state of the art: Develop efficient predictive modeling for macro-level quasi-static, fatigue, crush, crashworthiness.

Linking meso-level damage analysis to macro-level damage analysis Macro-scale composites modeling for UD, NCF & textile composites Modeling effect of imperfections (from manufacturing or pre-damage) in textile & NCF composites Development of suitable CAE models for joining technologies for novel and advanced materials

Basic mechanical properties simulation of AM components with CAE (stiffness, strength & NVH). Develop fast simulation strategies for vibro-acoustic analysis of lightweight material systems Virtual material characterization for multi-attribute model parameters of composites & LW materials. Develop a new hybrid joining. Assess feasibility of ‘bonding/debonding on demand.
