裂纹切割法及其应用

Crack-Cutting Method and Its Application

本文从柱体的扭转－弯曲问题的一般情况出发，介绍裂纹切割法的基本思想。首先给出单裂纹扭转－弯曲问题基本解，然后以弓形截面柱体的扭转为例，说明裂纹切割法的具体应用。

Starting from a general case for problems of torsion-bending of a cylinder,a so called crack-cutting method is presented in this paper.First of all,the fundamental solution for the problem of torsion-bending of a circular cylinder with single crack is given. Then applying the crack cutting method to the problem of torsion of a cylinder with arch shaped cross section as an example,related formulas and numerical results are presented.
