Abstract : A theoretical investigation of the dynamic interaction between the impact surface of an elastic body and a fluid is presented. From the investigation, it is concluded that since the dynamic interaction caused by ship slamming is closely related to the hydrodynamic incompressible phenomenon, the dynamic interaction is generated by the hydrodynamic added mass and the fluid damping. In the analysis of structural response with the dynamic interaction, therefore, the equation of motion has to include the added mass with the mass of structure and the fluid damping with the structural damping.
