The　paper　investigated　the　nonlinear　dynamics,　bifurcation　and　chaotic　dynamics　of　simply　supported　laminated　piezoelectric　composite　beam　with　axial　and　transverse　loading.　The　nonlinear　equations　of　motions　of　the　beam　are　first　derived　based　on　the　general　von　Karman-type　equations　and　the　Reddy　third-order　shear　deformation　plated　theory.　The　partial　differential　equations　are　discretized　to　the　ordinary　differential　equations　using　the　Galerkin　approach.　The　averaged　equations　are　obtained　with　the　method　of　multiple　scales.　Numerical　simulation　is　carried　out　to　investigate　the　periodic　and　chaotic　motions　of　the　beam.　The　results　show　that　the　chaotic　responses　of　the　beam　are　sensitive　to　the　piezoelectric　excitations.　Furthermore,　the　oscillation　of　the　piezoelectric　laminated　composite　beam　can　be　controlled　with　the　piezoelectric　excitation.
