| Research Abstract |
In order to develop hydroelasticity and hydroplasticity analysis methods that can follow the collapse behavior of a ship's hull girder in the extreme waves, (1) hydroelaticity analysis code including evaluation of impact loads, (2) hydroplasticity analysis code based on hydroplasticity theory, (3) a method to select extreme sea conditions, (4) a validation procedure for the hydroplasticity theory, are developed. In the item (4), a design methodology for a scaled model is developed. Further, influential parameters in strength and load models which govern the extent of the collapse, or consequence of the ship's hull girder collapse are specified.
