摘要
阐述了岩上类材料的非匀质特性,根据这种特性提出了对材料参数进行随机赋值的方法.为了对非匀质类材料的弹塑性破裂过程进行数值模拟研究,必须在有限元计算中实现材料的参数随机赋值.还给出了实例——平面应力状态下试样的弹塑性破裂过程的数值模拟分析.
The paper discusses the anisotropies ofrock-like materials and puts forward a random as-signment method for the material parameters. In order to study the elastoplastic failure process of anisotropic materials by means of numerical simu-lation, one must perform the random assignment of material parameters in the course of FEM computa-tion. The paper provides engineers with a platform along with application examples.
