Modified Mechanical Model of Normal Penetration of Rigid Projectiles into an Aluminum Target

Abstract:

Three-stage model of normal penetration of rigid projectile into aluminum plate is developed base on cavity expansion theory (plate thickness is smaller than projectile nose length). Correction method of the models is proposed and predicted results have good agreement with experimental data. The influence of target’s yield stress, target material parameter, sliding friction coefficient and projectile nose shape to penetration process is analyzed through numerical solution. It provides an effective mechanical analysis model for research of projectile impact resistance method to aluminum protective structure.
