摘要
从反平面切口问题的特征方程入手，采用换元逆幂迭代法并利用特征函数解析表达式已知及一些有效技巧研究了可以精确有效地求解具有任意张角、多种不同材料及不同边界条件的反平面切口问题的完备特征解的求解方法．
The superinverse iterative method is proposed to compute the accurate and complete eigensolutions for antiplane cracks/notches with multimaterials, arbitrary opening angles and various surface conditions. By taking the advantage of the knowledge of the variation forms of the eigenfunctions, a series of numerical techniques are proposed to simplify the computation and speed up the convergent rate of the inverse iteration.
