摘要
研究正交异性双材料反平面界面端的应力奇异性问题.采用复合材料断裂复变方法,得到应力奇异性指数λ的特征方程;利用Matlab,经过图形分析,得到双材料界面端楔形角θ1和θ2以及双材料参数对应力奇异指数λ的影响规律.
The stress singularity of interface end of orthotropic bi-materials anti-plane is studied.Based on the complex variable method for composite materials fracturing problem,the characteristic equation of the stress singularity index λ is deduced.The bi-material interface end wedge angles θ1 and θ2 are obtained from graphical analysis made by Matlab software.Finally,the law about the influence of the bi-material parameters on the stress singularity index λ is given.
