In the present paper a combined discrete-continual approach proposed in the previous work [1] is applied to simulation of finite thickness steel plate penetration by long tungsten rod. Advantages of this approach for description of penetration, which go from the combination of best properties from a continual numerical method and the discrete numerical method of movable cellular automata (MCA), are discussed and demonstrated by computation of practical problem. In computations the influence of such parameters as impact velocities and plate thickness on penetration process pattern is studied. The dependences of final velocity and rod length as functions of impact velocity and plate thickness are calculated and verified against experimental data. The calculated curves and overall behavior of the simulated system have demonstrated sufficient compliance with experiment, which proves that the proposed approach is effective for description of penetration and other complex dynamic problems.
