Contribution to the determination of high-order elastic stiffnesses from the measurement of BT-cut quartz resonators

The paper deals with the determination of the high-order constants possibility in the quartz using the measurement of the intermodulation products of the BT- and other cuts quartz resonators. The method is based on the Tierstens work (1983), which are provided on the AT-cut resonators vibrated in thickness-shear mode. The measurements performed on BT-cut quartz and other Y-cuts resonators given access to obtain of the effective non-linear constants of higher order. The experimental results and the comparison with the resonant method results are discussed
