Abstract

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.

提高水下爆炸冲击载荷下多层装甲系统的性能

摘要

本文对水下爆炸（UNDEX）复合装甲的抗震性进行了数值分析。通过测量目标层的有效应力和最大弹性挠度，研究了缩放距离和层厚度的影响。通过与实验结果比较验证结果后，利用响应面法得到了这些参数的最优值。观察到陶瓷层厚度对复合装甲动态抗力的影响最为显着，预测回归模型具有较好的准确性。
