ABSTRACT
In this chapter, the penetration of tungsten projectile into the composite ceramics – metal target is stimulated using Autodyne software. The behavioral equation used in this simulation is Johnson Cook for projectile and
metal and Johnson Holmquist for ceramic. Also, the equation of state used in tungsten projectile and metal is linear and in ceramic layer is Polynomial. In each model the output speed of the projectile is calculated and compared with the results of experimental tests. The results obtained indicate a good agreement between performed simulation and experimental results. Then Kevlar-epoxy and glass-epoxy polymer layer add to the ceramic/ aluminum target and projectile penetration resistance is investigated.
