A Resonant Vibration Technique for Laboratory Determination of Shear Wave Velocity

Abstract

Interest in laboratory determinations of shear wave velocity has increased in recent years. A simple procedure permits the determination of the shear wave velocity of materials represented by laboratory specimens from data obtained with resonant-frequency testing equipment which is available in many laboratories. The method is applicable for either cylinder or prism specimens. The only resonant test data needed is the frequency of the first mode of the torsional vibration. Weights, densities, compressional wave velocities, and elastic moduli, each a separate source of error, are not used in this determination. The paper discusses the test apparatus, test procedure, and the results obtained from typical shear-velocity tests employing the resonant vibration technique.
