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.
