3D Numerical Simulation for the Normal Penetration of Kinetic Energy Projectile into Concrete Target

With LS-DYNA3D. the normal penetration of kinetic energy projectile into concrete target is simulated. According to the simulation results, the penetration picture is obtained, and the process of penetration is analyzed; the curves affected by different initial velocity are drawn, and the law of penetration into concrete target affected by the initial velocity of kinetic energy projectile is studied, which can provide reference base for the study of penetration into concrete target.
