According　to　the　Reddy＇s　high-order　shear　deformation　theory　and　the　von-Karman　type　equations　for　the　geometric　nonlinearity,　the　chaos　and　bifurcation　of　a　composite　laminated　cantilever　rectangular　plate　subjected　to　the　in-plane　and　moment　excitations　are　investigated　with　the　case　of　1:2　internal　resonance.　A　new　expression　of　displacement　functions　which　can　satisfy　the　cantilever　plate　boundary　conditions　are　used　to　make　the　nonlinear　partial　differential　governing　equations　of　motion　discretized　into　a　two-degree-of-freedom　nonlinear　system　under　combined　parametric　and　forcing　excitations,　representing　the　evolution　of　the　amplitudes　and　phases　exhibiting　complex　dynamics.　The　results　of　numerical　simulation　demonstrate　that　there　exist　the　periodic　and　chaotic　motions　of　the　composite　laminated　cantilever　rectangular　plate.　Finally,　the　influence　of　the　forcing　excitations　on　the　bifurcations　and　chaotic　behaviors　of　the　system　is　investigated　numerically.
