摘要
研究置于无旋、不可压缩理想流体液面上的刚塑性圆板，在均布脉冲载荷作用下大挠度时的塑性动力响应问题．采用Ｈａｎｇｋｅｌ积分变换方法导出了圆板与流场流固耦合作用时的非均匀流体阻力．按国板的大挠度运动控制方程，给出了在“中载”作用下简史圆板塑性动力响应的解析解。
This paper concerns the dynamic plastic response of a circular plate resting onfluid subjected to a Uniformly distributed rectangular load pulse with finite deformtionl. It isassumed that the fliud is incompressible 'and inviscdus,and the plate is made from rigid-plastic material and simply supported along its edge. By using .the method of Hankel integraltransformation, the nonuniformly fluid resistance is derived as the plate and the fluid is coupled. Finally, an analytic solution of a circular plate under the medium load is obtained according to the equations of motion of the plate with finite deformation.
