多裂纹圆柱弯曲问题的奇异积分

Bending Integral Expressions of as Cylinder with Cracks

本文在文［１］的基础上，利用文［２］给出的无裂纹柱体弯曲问题的通解，求得了多裂纹圆柱横力弯曲应力函数及横截面剪应力的奇异积分表达式。本文方法借助数值积分表达式￣［３］，极易在微机上实现，可以完全类似文［１］所做的那样进行数值计算．

In this paper,based on paper[1] and[2],bending integral expressions of the stress function and shear stresses of a cylinder with several cracks are ob-tained.Using the numerical method of the singular integral equations￣[3], it is easy for us to do numerical calculation of the stresses and stress intensity factors,which is similar to that of paper￣[1].
