建立了全夹紧泡沫金属夹层板受低速大质量横击时的动力响应分析模型。考虑塑性弯曲与拉伸的相互作用，在分析中考虑了大挠度效应。得到了结构挠度、结构响应时间和冲击力的解析表达式。有限元结果验证了解析模型的准确性，得到了较好的一致性。
An analytical model is developed to predict the dynamic response of fully clamped square sandwich plate with metal foam core struck transversely by a heavy mass with low-velocity. Large deflection effect is incorporated in analysis by considering the interaction between the plastic bending and stretching. The analytical expressions are obtained for the structural deflection, the structural response time and the impact force. The finite element results validate the accuracy of the analytical model and good agreement is achieved.
