Improving the performance of a multi-layer armored system subjected to shock loading of an underwater explosion

In this article, the shock resistance of a composite armor subjected to the underwater explosion (UNDEX) was numerically analyzed. The effects of the scaled distance and the thickness of the layers have been investigated by measuring the effective stress and the maximum elastic deflection of the target layer. After validating the results by comparing with the experimental outcomes, the optimal values of these parameters have been obtained by using the response surface method. It was observed the ceramic layer thickness has the most significant effect on the dynamic resistant of the composite armor, as well as the predicted regression model has desirable accuracy.
