Thermomechanically coupled process modeling of microstructural material modifications ((2) M03)

第二阶段的目标是扩展已开发的材料模型，使复杂过程的双尺度模拟在可接受的计算工作量下成为可能。为此，应使用有效的数值算法和模型降阶技术。通过扩展到有限应变、基于位错密度的晶体塑性以及晶粒发展的相场建模，将实现对材料行为的更真实的描述。因此，可以对加载和修改之间的相关性进行详细分析，从而可以在微观和宏观两个相关尺度上识别过程签名组件。

The aim for the second phase is the extension of the developed material model in such a way that two-scale simulations of complex processes become possible at an acceptable computational effort. For this purpose efficient numerical algorithms and model order reduction techniques shall be used. A more realistic description of the material behavior will be achieved by the extension to finite strains, dislocation density-based crystal plasticity as well as phase-field modeling of grain development. As a result, a detailed analysis of the correlation between loading and modifications is possible and thus, Process Signature components can be identified at both relevant scales, the micro and macro scale.
