建议了二维蠕变损伤问题的有效模量法,基于热动理论提出了一个损伤演化方程,给出有效模量法和有效应力法的有限元解,并对西种方法进行了数值比较。
The effective modulus method for two-dimensional creep damage is proposed. Based on the theory of thermodynamic, a damage evolution equation is proposed. The finite element solutions of effective modulus method and effective stress method are given.
