摘要: 采用弹性平板理论及复变函数理论,对含孔无限大平板弹性波的散射及动应力集中问题进行了分析研究,建立了求解平板开孔动应力集中问题的复变函数方法。若同时采用映射变换,就为求解平板开任意形状孔的动应力集中问题提供了一种规范而有效的方法。为说明问题,本文给出了平板开圆孔及椭圆孔动应力集中因子的数值结果。Abstract: Complex varible analytic method for soving dynamic stress concentration in thin plate with cutouts is proposed. Numerical results for stress concentration of a plate with circular and elliptic holes are presented.
