The design and analysis of finite length multiple layered induced strain actuators to further extend the application of piezoelectric actuators in active structural control is investigated. A model of an arbitrary surface bonded multiple layered actuator is utilized to predict the applied force and moment of the ith piezoelectric layer on a beam. The equations of motion for the transverse vibration of a simply supported beam are derived using Timoshenko beam theory and cast in state space form. The forced response of the one dimensional actuator/substructure system to the piezoelectric induced loads is obtained using an assumed mode technique. The results of experiments performed on a simply supported beam, using various multiple layer piezoelectric actuator configurations for excitation, are compared to analytical predictions for model verification.
