Abstract

In the present study, the ballistic perforation resistance of steel/titanium/aluminum (STA) multilayer protective systems impacted by spherical, ogival, conical, and blunt projectiles was investigated experimentally, numerically, and analytically. The targets were manufactured via explosive welding technique to achieve a strong interfacial strength. The projectile nose shape was found to significantly affect the failure modes and ballistic limit velocities of the STA composite plate. Detailed three-dimensional finite element simulations were performed to provide insights into the penetration process and energy absorption characteristics of the STA composite plate. An analytical model was developed to predict the entry and exit penetration phases of a rigid projectile of different nose shapes into the STA target through ductile hole expansion. The model simplified the STA composite plate to be an equivalent monolithic based on the weighting of material resistance and specific cavitation energy in each layer. The analytical and numerical predictions of the residual velocity were in excellent agreement with the experimental data. The predicted evolution of projectile velocity with penetration depth was found to be in satisfactory correlation with those from the numerical simulation. The proposed analytical model shall be useful for designers of multilayer metallic protective structures against fragments from improvised explosive devices.

弹头形状对多层爆炸焊接板抗弹性的影响
本研究通过实验、数值和分析方法研究了钢/钛/铝(STA)多层防护系统在受到球形、椭圆形、锥形和钝形弹丸冲击时的抗弹道穿孔能力。目标是通过爆炸焊接技术制造的,以获得较强的界面强度。研究发现,弹头形状对 STA 复合材料板的失效模式和弹道极限速度有显著影响。研究人员进行了详细的三维有限元模拟,以深入了解 STA 复合板的穿透过程和能量吸收特性。建立了一个分析模型,用于预测不同弹头形状的刚性弹丸通过韧性孔扩展进入 STA 靶件的进入和退出穿透阶段。该模型根据各层材料阻力和比空化能的权重,将 STA 复合板简化为等效整体。残余速度的分析和数值预测与实验数据非常吻合。射弹速度随穿透深度的变化预测结果与数值模拟结果的相关性令人满意。所提出的分析模型对设计多层金属防护结构以防止简易爆炸装置碎片的产生很有帮助。
