蠕变损伤问题的有效模量法及差分解

EFFECTIVE MODULUS METHODS IN CREEP DAMAGE PROBLEM AND DIFFERENCE SOLUTION

本文在蠕变损伤问题中．以有效模量法将损伤变量引入本构方程，给出相应非线性问题的差分解；并将结果与一线实验数据及有效应力法的结果进行了比较．

This peper presents an effective modulus method, in which the damage variables is introduced into oonstitutive equations. The difference solutions of corresponding nonlinear problems are given. The numerical results are compared with that of one-dimension experiment and effective stress method.
