Material nonlinear piezoelectric coefficients for quartz

Abstract

An electroelastic or polarizing effect can be used to obtain material nonlinear pizoelectric or electroelastic coefficients. It is shown that these material coefficients, obtained from general rotationally invariant nonlinear equations for small field superposed on a bias, differ from those obtained by using the phenomenological expansion of the effective elastic constants. The eight independent electroelastic coefficients listed here was calculated by using experimental data available in the literature.
