Coupling to extension in a thickness-shear resonator due to relatively large thickness-shear deformation.
We show that in a plate thickness-shear mode resonator of rotated Y-cut quartz coupling to extension occurs when the shear deformation is no longer infinitesimal. A set of coupled equations is derived with which the effect of coupling to extension on the thickness-shear operating mode is examined.
