Simulation and Experiment of Projectile Penetrating into Concrete

The experiment of mock projectiles with diameter of 125mm vertically penetrating into concrete thick targets was performed. The final penetration depth of the projectile in target,the dimension of the impact crater,the spalling pit and the landing attitude of the projectile were measured. The model experiment work conditions of projectiles into concrete targets were simulated by the non-linear finite element software ANSYS/LS-DYNA. The numerical simulation revealed well the physical process of experiment damage image of the crater formation,the back scabbing and the crack occurring of concrete targets. The computing results of penetration depth,the displacement and velocity time history of projectile tails have perfect corresponded with the high-speed camera test data. These will supply an important foundation to the mechanism analysis of the concrete against projectiles.
