Multiscale modelling of the damage and fracture behaviour in nanostructured laminates (A06)

这个子项目的目标是开发连续介质力学材料模型，以便预测合作研究中心正在开发的涂层系统的损伤和断裂行为。为此，建立了一个具有梯度扩展的有限变形各向异性损伤破坏模型，该模型能够再现其他子项目的实验观测结果。这一所谓的宏观模型得到了微观结构模型的补充。校准和验证是与几个实验子项目合作进行的，这些子项目基于微米级的各种力学测试。

The aim of this subproject is the development of continuum mechanical material models in order to predict the damage and fracture behavior of the coating systems being developed in the collaborative research center. To this end, a viscoplastic anisotropic damage and failure model with gradient extension for finite deformations is to be developed which is able to reproduce the experimental observations of other subprojects. This so-called macroscopic model is complemented by a microstructural model. The calibration and validation is carried out in cooperation with several experimental subprojects based on various mechanical tests on the micrometer scale.
