摘　　要：研究了正交异性板中星形裂纹的平面弹性问题。采用复合材料断裂复变方法,选取适当的保角映射和特殊应力函数推出了裂纹尖端附近的应力场及Ⅰ型、Ⅱ型星形裂纹应力强度因子的解析解。The plane elastic problem about star crack of orthotropic composite plate was studied, the conformal mapping and special stress function, together with complex variable method of material fracture, are properly chosen to deduce the stress fields and the analytic solutions of the stress intensity factors for mode and mode problems at the crack tip.
