Multiscale modeling of TRIP/TWIP steel thermomechanical properties considering texture effects (C10#)

该项目的中心目标是建立一个建模工具，在任意热机械载荷下，捕获TRIP/TWIP钢在多个长度尺度上的各向异性。通过适当的均匀化假设，考虑了离散滑移和转变系统对整体单晶性能的贡献。通过多晶体的有限元模拟和多晶体的RVE计算，预测了材料的宏观行为。该模型的预测准确性是通过在合作研究中心（CRC）进行的宏观、中观和微观尺度实验的基础上进行严格的校准和验证来实现的。

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).
