本文采用流固耦合实验和有限元计算方法研究了深水和浅水条件下水背和空气背夹层板在爆炸载荷作用下的一维响应。夹层板包括刚性面板和低密度泡沫芯。实验是在透明的激波管中进行的，可以测量流体中的结构响应和空化过程。测量结果与预测吻合良好，并允许得出结论，在深水中水背夹层板的情况下，使用三明治结构的优点最大化。
Fluid-structure interaction (FSI) experiments and finite element (FE) calculations are performed in order to examine the one-dimensional response of water-backed and air-backed sandwich plates subject to blast loading in either deep or shallow water. The sandwich plates comprise rigid face sheets and low-density foam cores. Experiments are conducted in a transparent shock tube, allowing measurements of both structural responses and cavitation processes in the fluid. Measurements are found in good agreement with predictions and allow concluding that the advantages of using the sandwich construction over the monolithic one are maximised for the case of water-backed sandwich plates in deep water.
