The central objective of the project is to establish a modeling tool that captures the anisotropy of TRIP/TWIP steels across several length scales under arbitrary thermomechanical loading. The contributions of discrete slip and transformation systems to the overall single crystal properties are taken into account via appropriate homogenization assumptions. The macroscopic material behavior is predicted by means of finite element simulations of multi-crystals as well as RVE calculations for polycrystals. The predictive accuracy of the model is achieved through rigorous calibration and validation on the basis of macro-, meso- and micro-scale experiments conducted within the Collaborative Research Centre (CRC).

该项目的核心目的是建立一个建模工具，该工具在任意热力学负载下捕获几个长度尺度上的Trip/Twip Steels的各向异性。离散滑移和转化系统对整个单晶体特性的贡献是通过适当的均质化假设来考虑的。宏观材料行为是通过多晶体的有限元模拟以及多晶的RVE计算来预测的。模型的预测准确性是通过在协作研究中心（CRC）内进行的宏观，中尺和微尺度实验的严格校准和验证来实现的。
