In damage examples of hatch covers under green sea and bow flare subjected to slamming, external force which causes the structure damage comes from collision between hull structure and water around it. And the structural deformation and hydrodynamic pressure are so closely related with each other that a fluid-structure dynamics interaction must be considered. In the previous report, we developed a fluid-structure dynamics interaction computer program for fundamental study of these phenomena and some calculations were carried out for collision of a 2-D flat plate with water. In this report we added some functions to the program in order to calculate stiffened plates and cylindrical water body. The effect of stiffness of stiffened plate and water body shape on pressure and structural deformation is discussed.
