The response of an elastic-plastic thin plate under dynamic loading cannot be solved theoretically since both geometrical and material nonlinearities are involved and also highly coupled. Obviously, the response will be affected by material properties, geometries, and loads, whose effects are usually studied separately. In order to avoid repeated investigations and save costs, identifying the combined dominant dimensionless number must be essential.

动载作用下弹塑性薄板的主导无量纲数

由于涉及几何和材料非线性且高度耦合，弹塑性薄板在动载荷下的响应无法从理论上解决。显然，响应会受到材料属性、几何形状和载荷的影响，这些影响通常是单独研究的。为了避免重复调查并节省成本，确定组合的主导无量纲数至关重要。
