heal.abstract	A numerical simulation of the response of a flat plate subjected to hydrodynamic wave impact is presented. The formulation is based on a time domain solution of the large deflection plate equations using a finite difference mesh. The material behavior is elastic/viscoplastic, following the classical Perzyna model, and the procedure is validated against a series of model collision experiments. The correlation results were found to be good and the procedure was subsequently used to predict the response of plating subjected to wave impact loads, characterized by a steep rise to a maximum pressure followed by an exponential decay. A comparison with an analytical model was conducted and following this a parametric study of the characteristics of the pressure pulse was carried out. The paper concludes with a study of the effect of multiple wave impacts. It was found that, even though individual impacts may not cause rupture, a small number of these may lead to rupture of the plating, provided the maximum pressure is large enough.	en
