The　wing　is　simplified　as　the　cantilever　plate　model　based　on　the　engineering　background　of　the　aircraft　wing.　The　nonlinear　dimensionless　partial　differential　governing　equations　ol　the　composite　cantilever　piezoelectric　plate　under　the　combination　ol　transverse　and　in-plane　excitations　are　established　by　using　the　Hamilton＇s　principle.　The　Galerkin　approach　is　used　to　discretize　the　partial　differential　equations　to　the　ordinary　differential　equations　with　twodegree-of-freedom　under　the　transverse　and　parametric　excitations.　Meanwhile,　the　method　ol　multiple　scales　is　employed　to　obtain　the　four-dimensional　averaged　equation　considering　the　primary　parametric　resonance-1:3　internal　resonance.　Numerical　method　is　utilized　to　find　the　nonlinear　dynamics　responses　ol　the　composite　piezoelectric　cantilever　plate.　The　numerical　results　indicate　the　existence　ol　the　periodic　and　chaotic　responses.　The　influences　ol　the　transverse　excitation　and　piezoelectric　parameter　term　on　the　bifurcations　and　chaotic　behaviors　ol　the　composite　piezoelectric　cantilever　plate　are　investigated.　The　conclusions　are　instructive　to　the　practical　engineering.　©　2018　Journal　of　Dynamics　and　Control.　All　rights　reserved.
