In the paper we present the results of numerical and experimental studies of the impact of penetrators onto ceramic-composite and ceramic-metal targets. The main purpose of this paper is to show the possibilities of computer-aided interpretation of experimental results using "free particles" hydrocodes modelling of multilayered targets containing ceramics. Model for ceramics is based on the modified Steinberg's constitutive relations for non-damaged, ideal ceramic material. The model of the composite is based on the isotropic multilayered model of composite panels with different material characteristics in each layer. The numerical simulations and experiments were carried out for several combinations of ceramic/metal and ceramic/composite layers: Al2O3/aluminium, SiC/AlN/steel, AIN/SiC/steel, SiC/Al2O3/steel, AIN/Al2O3/steel and Al2O3/Dyneema. The exemplary results of our studies are shown. The results of theoretical and experimental investigations are in good agreement with one another.
