Summary: This project is a contribution to laminated plate optimization regarding external body penetration. Experimental approach to the problem has been known for a long time but they require long time and significant funds. That is the reason for advocationg the numerical investigation techniques in order to gain insight in a break-down mechanism. It is considered that elasto-plastic material model is sufficient for general insight into structural behaviour. In order to achive the results robust finite element should be implemented and a suitable contact procedure description during impact is to be adopted. Numerical analysis is to be verified with experimental data.

Keywords: plates, shells, dynamical analysis, impact analysis, finite elements

Research goals: Working computer model is needed for efficient analysis of laminated structures. Elasto-plastic material model would be sufficient to obtain some general knowledge regarding break-down mechanism of laminated plates and kinetic energy determination for laminated plate perforation. Using computer model one could compare laminated and homogenious structures of the same dimensions and obtain optimal solution for laminated plates regarding layer material and order, so that plate has maximal resistance on external body penetration.
