Numerical Analysis of Rod Kinetic Energy Projectile Penetrating into Multilayer Spaced Metal Plates

High velocity long-rod kinetic energy projectile penetrating into multilayer spaced metal plates was simulated,the residual length and the residual velocity of kinetic energy projectile with different velocity were analyzed.The result indicates the abrasion of the kinetic energy projectile result in the decrease of velocity,and the kinetic energy projectile with higher velocity is eroded more badly.
