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

该子项目的目的是开发连续力学材料模型，以预测在合作研究中心开发的涂层系统的损伤和断裂行为。为此，粘塑性各向异性损伤和故障模型与梯度扩展有限变形是开发，这是能够重现其他子项目的实验观察。这个所谓的宏观模型由微观结构模型补充。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尺度上的各种机械测试。

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.
