Abstract

Abstract: When a bullet strikes the heavy metal, it gets caught or stopped by that metal and makes an impact on the metal. The research work aims at the explicit dynamics analysis of striking of the bullet on heavy metal made components like hull material for boats, vehicles, armors and cryogenic propellant tanks etc., which helps to overcome the difficulties by improving material properties of armor such as strength, hardness etc. The result of the analysis may help in changing the proper-ties and improving the result. objective of this analysis is to find out at what velocity the projectile which is an INSAS Rifle bullet onto a target armor plate which is of a designated material or a structural combination like a laminated or corrugated sandwich panel structures of the same material to see which material or structural combination of the same material is best suitable to withstand penetration and to retain the mechanical strength with an extended life. Also, to com-pare the velocity of the projectile before and after impact, which can help in determining the effect of penetration on the armor, which can give data on which we can further improve to optimize the structural design of the armor. After creating suitable models using modelling software, Finite Element analysis s used to obtain solution for each model and hence find an optimal design of armor plate to with-stand the penetration of the bullet.
