The composite target is composed of several layers. In this case, it is steel armor or ceramics as the first layer and the second layer is made of aramid. These three materials are so different that for their modeling very different techniques are used. It is a Finite element method (FEM), Smoothed particle hydrodynamics (SPH), Discrete element method (DEM) and their combinations. All presented models are compared with experimental data of a real shooting or with data from a drop tester. During the firing of the projectile from the rifle there is a significant loading of the rifle barrel, which leads to vibrations of the barrel. This phenomenon is treated using numerical simulations as well as experimentally.
