Abstract

The purpose of the present work is to study the forced vibrations of piezoelectric (Sensor) -functionally graded material (FGM)-piezoelectric (actuator) slender sandwich beams submitted to active control. In the analytical formulation, both the proportional and derivative potential feedback control are considered via sensor and actuator layers by using the Bernoulli theory. The harmonic balance method is coupled with a one mode Galerkin procedure for a simply supported beam. The geometrically nonlinear coupling and piezoelectric effects lead to a nonlinear frequency amplitude equation governed by several complex coefficients. The frequency response curves are presented and discussed for various gain parameters and material properties.
