The Theoretical Ballistic Performance of Alumina Ceramics and the Effect of Nano Oxides Addition Using Finite Element Analysis
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
期刊介绍：
