Numerical Simulation on Perforation of Conical Nose Rigid Projectile into Thick Aluminum Alloy Target

Abstract

In this paper, the penetration and perforation process of the conical nose rigid projectile into thick aluminum alloy target was simulated numerically by using finite element method. The residual velocity was obtained by using numerical simulation. Time history of the projectile velocity is presented. Comparison of the present experimental results with numerical data from MSC.DYTRAN code indicates validity of the proposed simulation. The simulation results indicate that in the same conditions, the simulated residual velocity is in generally good agreement with the existing data. It shows the validity and exactness of the numerical simulation.
