The constitutive equations of a piezoelectric duo-bimorph

This paper describes the behaviour of a two-degrees-of-freedom piezoelectric actuator; based on piezoelectric bimorphs. The constitutive equations of the actuator are established, with a model derived from material resistance. They link external parameters (applied voltages; applied torque, force and distributed loads) and the internal variables (deflexion, slopes and volume displaced).
