Two-dimensional equations for electroelastic plates with relatively large in-plane shear deformation and nonlinear mode coupling in resonant piezoelectric devices

SummaryA set of two-dimensional equations for electroelastic plates in nonlinear face-shear motion are derived from the three-dimensional equations of nonlinear electroelasticity. The equations can describe the nonlinearity due to moderately large in-plane shear deformation associated with face-shear modes. The equations are used to study nonlinear face-shear vibration of a plate of 6mm crystals.
