摘　　要：首先研究了含孔边裂纹的各向异性材料在反平面剪切载荷作用下的反平面问题,得到了用级数表示的基本解和应力强度因子,之后用边界配置法求解了应力强度因子.通过算例分析表明:本方法精度高,运算量小,具有一定的工程应用价值.Anti - plane problem of anisotropic plate with cracks emanating from a hole is analyzed. A general solution and the stress intensity factor are obtained in terms of series expansion. The boundary collocation method is used to calculate the mode Ⅲ stress intensity factor. The results show that the method has better accuracy and takes less calculating time. Hence it is valuable in engineering calculation.

关 键 词：正交各向异性材料 边界配置法 应力强度因子
