ABSTRACT

Hydroelastic water impacts of panels with different deadrise angles, entry velocities, plate thicknesses, and edge boundary conditions are simulated by using the finite element method (FEM). Hydroelastic analysis of marine structures has been becoming increasingly important as an area of research in naval architecture. A considerable amount of work on the hydroelastic water impact problem of the wet-deck is being investigated using different approaches. Hydroelastic effects on slamming load and dynamic response of flexible panels are investigated by using the explicit FEM code Livermore Software Technology Corporation. The chapter shows that the hydroelastic effects are affected by the entry velocity, deadrise angle and the edge boundary conditions of the wedge. It presents the predictions of the slamming pressure and total slamming force on the elastic and rigid wedge panels, and the results of the structural deflection on the centre of the plates from the fully coupled method and the quasi-rigid/dynamic analyses.
