Abstract: The approximate expression of the fluid force between a floating laminated composite plate and liquid surface is obtained in this paper. Nonlinear dynamic equations including the effects of transverse shear deformation and solid fluid interaction are established by Hamilton's principle. The nonlinear dynamic solid fluid interaction response is solved by means of a difference method. The effects of non linearity and fluid depth under different loading forms on dynamic response are discussed.
