Abstract

In this article, a simple ANALYTICAL MODEL for a high velocity projectile penetrating into a ceramic-faced composite armor is presented. The output of the model is residual velocity, residual mass, projectile instantaneous velocity, and projectile instantaneous PENETRATION depth. The model is based on momentum and energy balance developed by Tate, Alekseeviski, and Chocron. In this model, PENETRATION process is investigated in two phases. The first phase is when ceramic conoid is formed and there is no PENETRATION into yarns and the second phase is when ceramic-conoid penetrates into backing composite material along with the projectile. The governing equations are developed and the results are analyzed. The model is tested for a tungsten rod and an alumina-faced dyneema and a kevlar. The results are in good agreement with numerical simulation and analytical results of Chocron & Galvez.
