摘要 讨论了无限大均匀压电材料中裂纹中心位于等腰三角形顶点且呈双周期分布的裂纹的反平面问题.利用保角变换及椭圆函数,求出了其封闭解,并且给出了应力和电位移强度因子表达式. In this paper, the anti-plane problem of the double period cracks in piezoelectric materials is investigated. Using the method of conformal mapping and elliptical function, the solution in closed form has been obtained, and then thereby the intensity factors of both mechanics and electric are obtained.
