Plastic behaviour of square plates subjected to impact loading is studied. It is assumed that the plates are formed from concentric squares with piece wise constant thickness. An approximate method of mode form motions resorting to the energy balance is used in order to predict maximal residual transverse deflections for plates made of Johansen´s material. Numerical results are presented for plates with two different thicknesses. Keywords: square plate, impact loading, inelastic material, optimization.
