An active control model of laminated piezothermoelastic plate

After the Hamilton principle for thermo-mechanical-electric coupling proble m is derived, the third-order shear deformation theory is extended to encom pass piezothermoelastic laminated plates. Based on the velocity feedback co ntrol, a model for the active vibration control of laminated plates with pi ezothermoelastic sensor/actuator is established. An analytical solution is obtained for the case of general forces acting on a simply supported piezot hermoelastic laminated plate. Numerical results are presented. The factors that influence the controlled responses of the plate are examined. (C) 1999 Elsevier Science Ltd. All rights reserved.
