开椭圆孔板的应力分析

Analysis of stress of plate with oval holes

运用复变函数保角变换求解无限大板开有椭圆孔时的孔边界处的应力分布规律,通过对开椭圆孔有限板的有限元分析,找出开椭圆孔有限板的应力分布与开椭圆孔无限板的应力分布的关系,达到用开孔无限板求解开孔有限板的目的。

With the transformation, the distribution of stress on the boundaries of holes is studied. By analyzing the finite plates with oval holes with the method of finite element, the relations to the distribution of stress between the finite plates with oval holes and the infinite plates with oval holes are found,in order to use the infinite plates with holes study the finite plates with holes.
