Abstract

AbstractThe present investigation has turned on the effect of nano CuO and TiO2 as a dopant on ballistic performance of sintered alumina armours and its results are simulated using finite element analysis. The model was constructed on armor-backing plate (Al6061-T6) assembly with a steel made core and copper made outer jacketed bullet at high velocity (820 m/s) by Ansys workbench. The depth of penetration of bullet drastically reduces to 36.17% due to addition of 2 wt% nano CuO with respect to pure alumina. The same optimized effect shown by 1 wt% nano TiO2 is about 40.42%. The residual velocity of bullet gradually decreases with time and there is more reduction of residual velocity of 38% and 56.82% at 140 μs by addition of 2 wt% nano CuO and 1 wt% nano TiO2 respectively with respect to pure alumina. The alumina armours with 1 wt% nano TiO2 addition showed the best ballistic performance as compared to nano CuO.Keywords: Ballistic performanceAlumina7.62 M61 AP (armour piercing) bulletDepth of penetration

氧化铝陶瓷的理论弹道性能及纳米氧化物对其影响的有限元分析

摘要本文研究了纳米CuO和TiO2作为掺杂剂对烧结氧化铝装甲弹道性能的影响，并对其结果进行了有限元模拟。利用Ansys workbench以820 m/s的高速度在钢芯、铜质外护套弹的Al6061-T6装甲背板组件上构建模型。与纯氧化铝相比，加入2 wt%纳米CuO后，子弹的穿透深度大幅降低至36.17%。1 wt%纳米TiO2的优化效果约为40.42%。在140 μs时，添加2 wt%的纳米CuO和1 wt%的纳米TiO2，子弹的残余速度分别比纯氧化铝降低38%和56.82%。与纳米CuO相比，添加1wt %纳米TiO2的氧化铝装甲显示出最好的弹道性能。关键词:弹道性能alumina7.62 M61穿甲弹穿深
