Abstract
All nine independent elastic constants cij of a YBa2Cu3O7−δ monocrystal were determined at room temperature using resonant ultrasound spectroscopy. Shear and Young moduli obtained from the cij by the Voigt-Reuss-Hill averaging method agree well with the pulse-echo results on a polycrystal. The Debye temperature calculated from the elastic constants agrees with the specific-heat measurement.
