摘　　要：从弹塑性损伤力学的瞬态边值问题的虚位移原理出发,利用有限元技术,导出了弹塑性损伤结构分析的线性互补方程,并给出了有限元算法·　这一方法适用于解决硬化。The virtual displacement principle of elasto_plastic damage mechanics is presented. A linear complementary method for elasto_plastic damage problem is proposed by using FEM technique. This method is applicable to solving the damage structure analysis of hardened and softened nonlinear material.
