NUMERICAL SIMULATION OF IMPACT EFFECT EXPERIMENT OF PROJECTILES

In order to extend the achievements of the model experiment,the work conditions of projectiles impacting on concrete with corundum-boulder matrix targets were simulated by the non-linear finite element software ANSYS/LS-DYNA. The numerical simulation reveals well the physical process of experimental at damage, inclading the crater formation, the back scabbing and the crack occurring in concrete targets, the corundum-boulder splash in the impact site of the concrete with corundum-boulder matrix targets front, and the damage of projectiles impacting against corundum-boulder. The numerical calculation results of penetration depth and displacement and velocity time history of projectile tails are in good agreement with the high-speed camera test data.
