| 摘 要： | 研究了正交异性双材料反平面界面裂纹问题。采用复合材料断裂复变方法，构造了特殊应力函数，通过求解一类偏微分方程组边界问题，推导出界面裂纹尖端附近的应力场、位移场及应力强度因子的表达式，确定了裂纹尖端应力场的奇异性，结果现实裂尖附近应力具有r^-1/2的奇异性，但没有振荡性。

| Abstract: | The problem of an orthotropic bi-material with antiplane interfacial crack was studied . Using composite complex function method of material fracture, the new specific stress function was constructed in this paper. By solring a class of partial differential equations boundary value problems, the expression of stress field, displacement field and stress intensity factor around the crack tip were derived, and the singularity of stress near the crack tip was fixed. The results show that the stress has singularity of r^-1/2 without oscillatory. |
