Optimization and Numerical Analysis of the Ricochet of Conical Nose Projectile in the Collision with Ceramic-Aluminum Armor

Abstract

The anti-armored bullets have more kinetic energy due to more mass than ordinary bullets, which increases their likelihood function of penetration for different target, so it is necessary to seek solutions to reduce the possibility of penetration of these The type of bullets and the increasing likelihood function of ricochet them, is one of the ways to increase the likelihood function of ricocheting bullets by leveling the surfaces. One of the most important parameters influencing penetration is projectile impact velocity. The mechanism of penetration varies in different velocity ranges. In this paper, the phenomenon of buckling steel cone with a nose cone in a collision with ceramic targets was investigated by explicit finite element method using LS-Dayna software. In this study the critical angle of ricochet at different velocity and optimization of the optimal thickness ratio of ceramic / metal targets has been considered. The results of numerical simulation with other empirical results of other researchers have been evaluated that show good accuracy.
