The aim of the subproject is to model the material behaviour during mechanical joining processes as accurately as possible. Challenges arise in the simulation of the strain rate and temperature dependency of the materials as well as in the coupling of plasticity, ductile damage, and temperature. Moreover, novel numerical approaches are investigated for joining process simulations and combined with the developed material models. Both will be implemented accurately and efficiently, and experimentally validated.

该子项目的目标是尽可能准确地模拟机械连接过程中的材料行为。在模拟材料的应变率和温度依赖性以及塑性、延性损伤和温度的耦合方面出现了挑战。此外，还研究了用于连接过程模拟并与开发的材料模型相结合的新颖数值方法。两者都将准确有效地实施，并经过实验验证。
