MCA method for numerical simulation on penetration of long rod projectile into concrete targets

The basic model and equations of Movable Cellular Automata (MCA) method were described for simulating the high-rate penetration problems. On the basis of the developed MCA method, the 2D numerical simulations on the penetrations of projectile into concrete targets were performed. The deformation processes of the projectile and target were obtained. In addition, the penetration depth vs impact velocity was given. The numerical results agree well with the previous experimental observation. The numerical example above proves that this algorithm is powerful and efficient for simulating the high-rate penetration problems.
