夹层板是一种比刚度大、比强度高的结构形式，根据文献将典型加筋板等效为最优夹层板，采用非线性数值方法，对爆炸冲击波作用下方形蜂窝夹层板及填充超弹性材料的方形蜂窝夹层板响应进行数值计算，分析填充超弹性材料夹层对夹层板各部位加速度、速度及位移响应的影响，对比不同爆距下夹层板响应，并分析填充超弹性材料对夹层板吸能的影响。从计算结果可知填充超弹性材料可有效减小爆炸载荷作用下夹层板的响应，减小夹层板面、背板间相对变形。
Sandwich plate is a new structural style with high specific stiffness and specific strength, the optimal square hole honeycomb sandwich plate was come from traditional ship stiffened plate according to reference method, the response of square hole honeycomb sandwich plate with or without hyperelastic material inside under blast loading were computed by non-linear numerical analysis, the acceleration, velocity and deformation response of of square hole honeycomb sandwich plate with or without hyperelastic material were analyzed, the response of sandwich plate under different blast distances were compared, and energy absorption of sandwich plate with or without hyperelastic material also were analyzed. Sandwich plate has low response under blast loading with hyperelastic material inside, and has low relative deformation between front panel and back panel.
