| Abstract: | The analytical expression of fluid force between a floating laminated composite strip and liquid surface was obtained.The nonlinear control equations of dynamic buckling including the effects of transverse shear deformation and solid fluid interaction were established by Hamilton's philosophy.The solid fluid interaction dynamic buckling under in plane loading was solved by means of the difference method.The effects of lamination angles,layer numbers,fluid depth,loading forms and initial imperfections on dynamic buckling were discussed. |
