Numerical Simulations on Penetration of Rod Projectiles into YB-AD90 Ceramic Targets

JH-2 constitutive model parameters of YB-AD90 ceramic were derived from experiments and literatures. The penetration depths and the dynamic penetration processes of rod projectiles into YB-AD90 ceramic targets were numerically simulated using Autodyn-2D. The results indicate that the simulation method and parameters of JH-2 model are acceptable. Some important features in the penetrating processes such as the shape change of the projectile head, the material fragmentation, and the channel collapse are simulated and discussed. The simulation results are consistent with experimental results.
