Experimental firing tests with real ammunition to an armor plate “strike face” at various impact velocities of the projectile were conducted, together with simulations of this situation. After finding the parameters of the damage model, the results of the simulation showed a good agreement with the experimental data. This model is ready for a simulation of an impact sandwich armor which will be carried out after determining necessary mechanical properties of the aramid composite “back face” material to support the development of elements for vehicle ballistic protection.
