摘要
将正交异性、各向异性纤维复合材料平面断裂问题中的Ⅰ型、Ⅱ型、Ⅰ+Ⅱ型、Ⅲ型裂纹以及受纯弯、受纯扭、受弯扭裂纹的探讨归结为求解一类(14个)偏微分方程的边值问题。在此基础上采用复变函数方法可以求出上述各型裂纹尖端附近的断裂力学重要参量:应力、应变、位移等。
The search for plane fracture problems of orthotropic and anisotropic composite material can be classified as solving a class of boundary value problems of partial differential equation. By using a complex variable method and solving the fourteen boundary value problems of partial differential equation, the important parameters as stress ,strain and displacement of fracture mechanics are found.
