Abstract: Based on the two-dimensional constitutive relationships of the piezoelectric material, an analytical solution for an intelligent beam excited by a pair of piezoelectric actuators is derived. With the solution the force and moment generated by two piezoelectric actuators anda pair of piezoelectric actuator/sensor are obtained. Examples of a cantilever piezoelectric laminatedbeam or a simply supported piezoelectric laminated beam, applied with voltages, are given.
