Slamming is recognised to be a major design problem for high speed ships. To avoid structural damage, or the imposition of speed reduction in severe seas, the designer needs to be able to predict slam-induced stresses. This proposal aims to predict the slamming induced pressure, stress and deformation by means of a coupled analysis of the fluid structure interaction.It will be based on a procedure which is being developed by the proposers for the nonlinear time domain analysis of the free surface flow around a rigid body. This is set up as an initial value problem in terms of a velocity potential, which is solved by the finite element method. The solution is stepped forward in time, with a new element mesh generated at each time step to match the local geometry of the body and the free surface. The mesh is based on a sophisticated quadtree/octree grid generation algorithm. The procedure is to be extended in this project to deal with the nonlinear flow interaction with a flexible structure, with a finite element idealisation also being used to represent the elastic structure. Results will be obtained for simple archetypal structures and for more realistic geometries. It is proposed to compare these results with those developed by alternative methods (eg by Germanische Lloyd).
