This article deals with a general method for finding the equations of the dynamic response of a bimorphous piezoelectric structure through a variational formulation. First, a method of resolution is proposed then a general electric equivalent circuit involving the design parameters of the device is deduced, followed by the description of application to a travelling-wave stator.
