带裂纹矩形截面柱体的Saint-Venant扭转

Saint-Venant′s Torsion of a Rectangular Cylinder with Cracks

在基于解析法的基础上 ,采用级数展开的方法 ,给出了含裂纹矩形截面柱体 Saint- Venant扭转的柯西型奇异积分方程 ,并利用奇异积分方程的数值积分理论 ,对中心单裂纹下的应力强度因子和抗扭刚度作了数值计算。

Using series expansion, a system of singular integral equations for solving Saint Venant's torsion problem for a rectangular cylinder containing arbitrary cracks are given, then the stress intensity factors and the twist rigidity for a rectangular with a single crack is calculated.
