摘要
本文利用单裂纹解,将裂纹的不连续解分离,然后使用常规的调和函数解,使带有偏心裂纹或边裂纹的柱体扭转问题,归为解一组混合型积分方程,这组方程可联合使用奇异积分方程数值法与边界元法进行求解.文中对若干典型的裂纹柱体作了数值计算,得到了柱体的抗扭刚度和裂纹端点的应力强度因子.
Using the single crack solution and the regular solution of harmonic function, the torsion problem of a cracked cylinder is reduced to solving a set of mixed-type integral equations which can be solved by combining the numerical method of singular integral equation with the boundary element method.Several numerical examples are calculated and the stress intensity factors are obtained.
