Abstract :
We studied the electromechanical coupling factor of an electroelastic plate from the nonlinear theory for large deformations and strong fields, in particular the effects of nonlinear elastic constants on the factor. The case of nonlinear thickness-shear deformation of an AT-cut quartz plate is calculated as an example.
