Analytical solutions to study the elastic dynamic responses of a flat composite plate are developed based on the orthotropic thin plate theory and modal analysis. The spatially uniform slamming pressure is simplified to two types of impact loads, i.e. an exponentially decaying impulse and a triangle impulses, which are characterized by the peak value and loading duration. In order to investigate the influence of the peak pressure and the loading duration on the plate structural behaviour, the dynamic responses of a simply supported flat plate under various impulses are calculated. Results show that the peak pressure affects only the amplitude of the response, while the loading periods affect both the phase and amplitude. Two numerical methods, i.e. a FEM dynamic analysis and a full coupled hydroelastic analysis, are applied to validate the analytical model and to investigate the hydroelastic effects. Comparisons of the analytical solution and hydroelastic analysis show that the slamming pressures on the flat composite plate fit the proposed triangle load model. With proper values on the peak pressure and loading period, the analytical model could provide good predictions on the structural deflections.
