CORRECTIONS TO THE CONSTITUTIVE EQUATIONS OF PIEZOELECTRIC LAMINATED BEAMS THROUGH A MIXED VARIATIONAL APPROACH

Abstract : Beam models of piezoelectric laminates derived from three-dimensional theories by assuming either the plain-stress or the plain-strain conditions in the beam axis-thickness plane can introduce significant errors in the estimate of the beam constitutive coefficients. In this paper a coupled Euler-Bernoulli like model including 3D effects through a mixed variational formulation is discussed. We report the results of numerical and experimental tests which validate the approach and show the limit of standard modelling techniques.
