  • Abstract
    Thermal coefficients of elastic constants of LGS and LGT crystals have been determined from frequency-temperature curves of contoured resonators operating in thickness modes. Effect of the trapping of the vibration has been taking into account in order to improve the accuracy. In a first step, thermal sensitivity of stiffness coefficients in lagrangian description are obtained. Thermal sensitivity of usual elastic constants are further deduced.
