本文综述了多尺度和多学科的变形和损伤分析领域的研究进展。本文对X2 CrNiMo 18 -15-3（AISI 316L）不锈钢的韧性破坏进行了实验测量和数值计算。采用嵌入式数值技术，其中晶体塑性理论被用来表示塑性变形的材料和单元去除技术的基础上的Rice&Tracey损伤模型的韧性孔洞生长来模拟损伤启动内的材料，这是在实验中观察到的。此外，晶体塑性模型是由一个层次的多尺度方法连接纳米，微米和介观尺度的支持。
This paper serves as an overview of the ongoing research in the field of multiscale and multidisciplinary analysis of deformation and damage in the case of oligocrystalline structures. The research focuses on experimental measurement and numerical calculation of ductile failure in the X2CrNiMo18-15-3 (AISI 316L) stainless steel. An embedding numerical technique is employed where crystal plasticity theory is used to represent plastic deformation in the material and element removal technique based on Rice&Tracey damage model for ductile void growth to simulate damage initiation inside the material, which is observed in the experiments. Additionally, the crystal plasticity model is supported by a hierarchical multiscale approach connecting nano-, micro- and meso-scales.
