The Elastic Constants, Strength and Density of Greenland Snow as Determined from Measurements of Sonic Wave Velocity

Abstract

The measurement of sonic wave velocities on undisturbed samples of Greenland snow was accomplished using piezo-electric transducers in conjunction with a soniscope which provided the exciting source and the time measuring device. These velocity measurements were correlated with density determinations, crushing strength tests, and the elastic constants of the Greenland snow samples for a density range of 0.4 to 0.9 g/cc. Empirical formulae were derived that present the density, crushing strength, and the elastic constants as functions of sonic wave velocity.
