Analysis of load history dependent evolution of damage and microstructure for the numerical design of sheet - bulk metal forming processes (C04)

采用有限元模拟方法，对板料整体成形零件的力学性能进行了预测。特别是，在动态加载过程中考虑了应变率相关的材料行为。考虑到载荷历史对硬化和损伤的影响的材料模型将得到应用和改进。电子显微镜和一种改进的共振法被用来确定制造部件的局部性能，如刚性和损伤。

The mechanical properties of parts manufactured by sheet–bulk metal forming are predicted by means of finite-element simulations. In particular, the strain-rate-dependent material behaviour during dynamic loading is considered. Material models, which take into account the influence of the load history on hardening and damage, will be applied and enhanced. Electron microscopy and a modified resonance method are employed to determine local properties in the manufactured parts such as stiffness and damage.
