Abstract

This numerical study is dedicated to investigating the ballistic performance of three-component integral body armor comprising ceramic façade, layers of ultra-high molecular weight polyethylene fiber-based composite (Dyneema) and closed-cell aluminum foam against NIJ-Type IV armor-piercing bullets. A numerical model of integral armor with a ceramic façade and a fiber-reinforced composite backing plate was developed in IMPETUS Afea Solver and verified against experimental data. The verified model was used to design a "baseline configuration" of two-component integral armor that can stop the NIJ-Type IV projectiles. Three-component armor configurations were obtained by introducing layer(s) of closed-cell aluminum foam into the laminate. Laminates with different stacking sequences of composite and porous layers and different foam relative densities were studied and compared with the baseline two-component configuration. The study presents new insights into the mechanics of perforation of integral armor with closed-cell foam and provides design recommendations for such armor systems.

闭孔泡沫铝整体装甲弹道性能的数值研究

本数值研究旨在研究由陶瓷表面、多层超高分子量聚乙烯纤维复合材料(Dyneema)和闭孔泡沫铝组成的三组分整体防弹衣对抗nij - IV型穿甲弹的弹道性能。在动力求解器中建立了陶瓷面板-纤维增强复合材料背板整体装甲的数值模型，并与实验数据进行了验证。该验证模型用于设计一种能够拦截nij - IV型弹丸的双组份整体装甲的“基线配置”。通过在层压板中引入闭孔泡沫铝层，得到了三分量的装甲结构。研究了复合层和多孔层不同堆叠顺序、不同泡沫相对密度的层压板，并与基准双组分结构进行了比较。该研究为闭孔泡沫整体装甲的穿孔力学提供了新的见解，并为此类装甲系统提供了设计建议。
