On Dynamic Stress Concentrations in Thin Plates with Internal Forces

基于有中面力平板小挠度弯曲波动理论，利用复变函数方法，分析研究了含孔平面力板弹性波散射与动应力集中问题．得到了传播弯曲波时此种平板弯曲波动问题的分析解．分析了双向均匀拉力对弹性波散射及动应力系数的影响．给出了平板含圆孔及椭圆孔的动应力系数的数值结果，并对数值结果进行了讨论．

Based on the governing equation for flexural wave of thin plates, dynamic stress concentrations in the plate with internal forces have been studied. An analytic method to solve dynamic stress concentrations on the edge of a cavity is obtained. Numerical results for dynamic moment factors of plates with a circular and elliptic cavities are presented.
