Abstract : A system of approximate two-dimensional equations for the extensional and flexural motion of thermopiezoelectric plates subject to large electric fields is derived from the three-dimensional equations of thermopiezoelectricity for small strains, small temperature variations, and strong electric fields. The two-dimensional equations are derived by introducing an appropriate expansion for the mechanical displacement, temperature field, and electric potential in the thickness-coordinate and integrating the balance laws and constitutive relations.
