| 摘 要： | 根据线弹性断裂力学分析中常用的叠加方法,把一个有限域内的裂纹问题分解成无裂纹部分和裂纹部分的叠加来求解.其法只需较少的离散单元就可达到理想的精度,是求解裂纹问题的一种简单有效的方法.

| Abstract: | Based on the propertis of the linear elastic fracture mechanics,a crackprobleml of the finite region can be solved by superposition of an uncrackedpart of the finite region and a cracked part of infinite domain.Numericalexamples show that good results could be obtained with relatively fewetemenfs when using the treatment.Therefore,it is a kind of effetivemethod for solving the problems of linear elastic fracture mechanics. |
