摘要
研究集中力作用下各向异性材料的Ⅲ型裂纹问题。庄用解析延拓方法和扰动的概念，推导了位移和应力的解析表达式，给出了在力强压因子的基本解。正交各向异性和各向同性材料的应力强度因子均为本文的特例。
The mode Ⅲ crack problem of anisotropic materials subjected to a concentrated force is studied. The analytical expressions of the displacement field and stress field are derived by using the method of analytical continuation and the concept of perturbation,and the fundamental solution of the stress intensity factor is given. The stress intensity factors of both orthotropic and isotropic materials can be obtained from the present results.
