有限元方法是研究材料力学行为的一个有效工具。在针对于材料的损伤问题的有限元方法中，应变本构方程和损伤演化方程可以处理成耦合的，也可以是非耦合的，并因此形成了三种方案：①“应变本构关系”、“损伤演变规律”和“裂纹扩展规律”各自独立，并将损伤和断裂处理分成两
Finite element method is an effective tool to study the behavior of material mechanics. In the finite element method for the material damage problem, the strain constitutive equation and the damage evolution equation can be treated as coupled or uncoupled, and thus three schemes are formed: ① “Strain constitutive relation,” “ Damage Evolution Law ”and“ Crack Propagation Law ”are independent, and the damage and fracture treatment is divided into two
