摘　　要：建立以裂纹表面位移为未知函数的超奇异积分方程,利用有限部积分原理和边界元法来求解该方程.运用该方法计算出矩形裂纹的I型应力强度因子.In this paper a hypersingular integral equation with the unknown displacement is developed. To solve the equation, the principle of finite-part integral and boundary element method is used. By using the method mentioned above, the stress intensity factors of rectangle crack are calculated.
