ON THE APPLICATION OF THE HASKIN-HANAOKA RELATIONS TO HYDROELASTICITY PROBLEMS

The Haskin-Hanaoka relations for obtaining the wave-exciting forces, given the incoming and radiation potentials in floating rigid- body dynamics, are extended to deformable-body dynamics in the presence of a free surface and within the assumptions of linear potential theory. These relations are applied to the mode- superposition and the direct methods of solution of hydroelasticity problems. In other words, it is shown that regardless of the structural analysis method used in a hydroealsticity problem, the Haskin- Hanaoka relations can be used to calculate the wave-exciting forces without solving for the diffraction potential explicitly. These relations can also be used in the composite singularity distribution method to increase further the computational efficiency.
