This paper focuses on large inelastic deformation of plates made of marine grade aluminium alloys subjected to dynamic pressure loads that may arise from slamming. Simple design equations for predicting the permanent damage of plates are derived based on rigorous parametric studies performed using non-linear finite element method. The impact pressure profile is idealised as a triangular pulse with linear decay. Simply supported and fully clamped boundary conditions are assumed at the edges of the plates. The aluminium alloy grade 5083- H116 is considered. The effect of the heat affected zone at the plate boundaries is also assessed. The derived simple equations are in good agreement with finite element analysis results and therefore can be used for design purposes and serviceability limit state assessment of aluminium platings in high-speed vessels.
