Abstract

The theory and typical numerical results of a second order nonlinear hydroelastic analysis of floating bodies are presented in a series of papers in which only nonlinearity in fluids is considered. Under the assumption of linear fluid, the hydroelastic analysis methods of nonlinear structure are introduced in this paper. With the examples of the motion and displacement reponses of a floating plate undergoing large vertical deflections in multidirectional waves, the analysis method of the couple action between the vertical deflections in multidirectional waves, the analysis method of the couple action between the vertical displacement and the fluid are presented in the frequency domain. The influence of the membrane forces to the vertical displacements, bending moments and the stress are discussed. The numerical results indicate that the membrane forces have influence on the vertical displacement, bending moments and stresses, and can not be neglected in some cases.
