Single-crystal elasticity of stishovite: New experimental data obtained using high-frequency resonant ultrasound spectroscopy and a Gingham check structure model

► High frequency resonant ultrasound spectroscopy was applied for single crystal stishovite. ► The resulted elastic constants are consistent with inelastic X ray scattering rather than Brillouin scattering. ► The present bulk modulus is consistent with that of compression experiment. ► A macroscopic Gingham check model was proposed to understand the characteristics of stishovite elasticity.
