A Study on the improvement of element division of hydrid integral method for analyzing of the offshore structures

해양구조물의 동요해석을 위한 Hybrid적분방정식법의 요소분할 개선에 관한 연구

Recently, It is proceeding the project of offshore structures in the many contury. A hybrid boundary-integral method is developed for computing wave forces on floating bodies. In this method, using the cylindric boundary for deviding elements, it is convenient to analysis but is difficult to apply to the rectangular or slender bodies. Thus, in this paper, I propose the new method by using the fictitious vertical cylinder of arbitary cross-section and shows results of the numerical analysis for testing.
