| 摘 要： | 基于薄板粘弹性弯曲波动方程，采用复变函数方法对平板开孔弹性波的散射问题进行了研究，得到了传播稳态波时此种平板弯曲波动问题的分析解。分析了材料粘性阻尼及入射波距离对开孔弹性波散射结果的影响。作为算例，给出了平板圆形开孔的动应力集中系数的数值结果，并对计算结果进行了分析讨论。

| Abstract: | Based on the wave equation of viscoelastic plates,scatterring of flexural waves by cutouts and dynamic stress concentrations in the plate have been studied.An analytic me- thod to solve dynamic stress concentrations in the plate with a cutout is proposed. The ef- fect of viscous damping of material on dynamic stress concentration factors has been analyzed. Numerical results for dynamic moment factors of plates with a circular cutout are presented. |

| Keywords: | thin plate cutout: viscoelastic waves dynamic stress concentration |
