正交异性双材料反平面界面端应力奇异性研究

摘要

Anti-plane orthotropic bi-materials interface stress singularities is focused on the study. By means of stress singularity order A of characteristic equation, by the pattern comparative analysis and the property of trigonometric function and examples, a conclusion the bi-material interface end wedge angle θ1 ,θ2and double parameters of materials are draw, the influence law of the stress singularity exponent.%研究了正交异性双材料反平面界面端的应力奇异性问题.借助应力奇异指数λ的特征方程,经过图形对比分析,验证了应力奇异指数λ与双材料参数及双材料楔形角有关,并且利用三角函数的性质和算例,得到了双材料界面端楔形角θ1和θ2以及双材料参数对应力奇异性指数λ的影响规律.
