The nonlinear mechanics for piezoelectric laminates andplates is presented, including nonlinear effects due tolarge displacements and rotations. The mechanics isincorporated into the piezoelectric mixed-field laminate theory.Using this mechanics, a nonlinear finite-element method and anincremental solution are formulated for the nonlinear analysisof adaptive plate structures. An eight-node-plate finiteelement is developed. The mechanics is applied to predict thebuckling of piezoelectric plates induced by combinedelectromechanical loading. Application cases quantify themechanical buckling of composite beams and plates withpiezoelectric sensors, the piezoelectric buckling of activebeams and plates, and the feasibility of active bucklingcompensation.
