| Abstract: | In this article, the 2-D numerical simulations of the penetrations of projectile into soil-concrete targets are completed by Movable Cellular Automata(MCA) method. The deformation processes of the projectile and target are obtained. In addition, the penetration depth vs impact velocity is given. It is demonstrated that the numerical results are well corresponding to experimental observation.The numerical example mentioned above proves that this algorithm is powerful and efficient for simulating the penetration of projectile into multi-layer targets. |
