The　nonlinear　dynamic　responses　of　a　composite　laminated　cantilever　rectangular　plate　under　the　in-plane　and　moment　excitations　are　studied.　The　Reddy＇s　higher-order　shear　deformation　theory　and　the　von　Karman　type　equations　for　the　geometric　nonlinearity　are　used　to　establish　the　governing　equations　of　motion.　The　nonlinear　governing　partial　differential　equations　of　motion　for　the　composite　laminated　cantilever　rectangular　plate　are　derived　by　using　the　Hamilton＇s　principle,　which　are　transformed　into　a　two-degree-of-freedom　nonlinear　system　by　using　the　Galerkin　approach.　A　new　kind　of　expression　of　the　displacement　functions　is　given.　The　case　of　1:2　internal　resonance　and　primary　parametric　resonance　is　taken　into　account.　The　influence　of　the　in-plane　and　moment　excitations　on　the　nonlinear　vibrations　of　the　composite　laminated　cantilever　rectangular　plate　is　discussed　by　using　numerical　simulation.　The　numerical　results　demonstrate　that　there　exist　the　bifurcation　and　chaotic　motions　of　the　composite　laminated　cantilever　rectangular　plate.　The　nonlinear　frequency-response　curves　of　this　system　under　different　excitations　are　investigated　to　show　the　relationships　between　the　excitations　and　the　amplitudes　of　the　first　two　modes.　(C)　2013　Elsevier　Ltd.　All　rights　reserved.
