The approximate expression of the fluid force between a floating laminated composite plate and liquid surface was derived. Nonlinear dynamic equations including the effects of transverse shear deformation and solid-fluid interaction were established by using Hamilton's principle. The nonlinear dynamic solid-fluid interaction response was solved by means of a difference method. The effects of nonlinearity and fluid layer depth under different loading forms on dynamic response were discussed.
