正交异性双材料裂纹与界面垂直时应力的奇异性分析

The analysis of singularity of crack and interface vertical of double orthotropic composite materials

本文通过构造特殊的应力函数对正交异性复合材料裂纹与界面垂直的情形进行了研究.得到了双材料裂纹与界面垂直时裂尖的特征方程,并对特征值进行了数值分析.结果显示:应力具有幂次奇异性,或没有奇异性.

This paper studies crack and interface vertical of double orthotropic composite materials by constructing new stress functions.The characteristic equation of crack tip of crack and interface vertical is derived and the numerical analysis for characteristic value is made.The results show that the stress has either power singularity or not.
