Development of a theoretical treatment of fluid structure interaction effects on floating and submerged structures, taking into account: 1. Efficient modelling of infinite fluid medium; 2. Modelling of underwater explosions and earthquakes; 3. Modelling of cavitation and other fluid non linearities; 4. Comparison of implemented developments with test data. (1) Survey of previous research with the aim of highlighting current areas of weakness in research. (2) In order to assess the previously developed fluid elements, a preliminary study will be undertaken to determine the eigenvalues and eigenvectors of the fluid finite elements and mesh configurations. (3) Refinement of the far field model for the analysis of submerged structures in infinite fluid media subjected to explosions. This currently includes an acoustic approximation to model the infinite fluid medium and a facility for step and exponential plane waves (to model explosions at a distance sufficiently away from the structure). It will be extended to cover spherical shock waves and a more refined acoustic approximation. (4) Comprehensive numerical studies covering various types of loading, their frequency content and duration (to investigate the frequency dependence of the method)and the extent of the finite element fluid mesh (to investiaget the effect of cavitation). (5) Performing systematic numerical investigations to give broad guidelines for the parameters required in the analysis of submerged structure fluid systems. Comparison with existing data held by DRA will be undertaken.
