Hydroelastic Responses of a Very Large Floating Structure in Time Domain

시간영역에서 초대형 부유식 해양구조물에 대한 유탄성 운동해석

This paper is transient motions of a very large floating structure subjected to dynamic load induced by wave. A time domain method is applied to the hydroelasticity problems for this purpose. The method is based on source-dipole and FEM scheme and on Newmark $\beta$ method to pursuit time step process taking advantage of the memory effect. The present method is appied to hydroelastic response analysis in regular waves and impact responses due to dropping aircraft.
