An instrument for measuring the elastic moduli at several ultrasonic frequencies, using a single quartz crystal, has been developed. In the past an array of pairs of oscillators was used as part of the piezoelectric ultrasonic composite oscillator technique to measure the dynamic Young’s modulus and shear modulus at several ultrasonic frequencies. Experimentation was done using the conventional composite and the new single crystal systems at 40, 80, and 160 kHz on brass and aluminum samples, both in the longitudinal and torsional modes. The good agreement between these systems is indicative of the validity and applicability of the new design.
