摘要
本文根据弹塑性损伤力学的瞬态边值问题，提出了损伤分析的虚功原理，利用有限元技术，导出了弹塑性损伤结构分析的线性互补解法。本方法计算格式紧凑，求解规模较小，适用于解决硬化、软化等材料的损伤结构分析。
This paper presents the virtual displacement principle of elasto－plastic damage mechanics． A linear complementary method for elasto－plastic damage problems is proposed by using FEM technique．This method is applicable to solving the damage structure analysis for non－linear material of harden softer etc．its calculating form is comgact and the model’s scale is smaller than others
