Vibration Suppression of Composite Beams with Piezoelectric Devices Using a Higher Order Theory
A model to demonstrate the dynamic response of piezocomposite beams is presented. Direct and converse effects of piezoelectrics are utilized in formulating the model. The formulation is based on a higher order shear deformation theory and accounts for lateral strains. The piezoelectric sensors and actuators can be surface bonded or embedded and can be either continuous or segmented. The independent behavior of the sensor and actuator is studied. Numerical results are presented to demonstrate the ability of the closed loop system to actively control the vibration of laminated beams.
