Record #125450:

Application of a mixture theory to stress waves in snow / George E. Austiguy, Jr, Robert L. Brown.

Title: Application of a mixture theory to stress waves in snow / George E. Austiguy, Jr, Robert L. Brown.
Author(s): Austiguy, George E.,
Brown, Robert L.
Date: 1993.
In: Annals of Glaciology. (1993.), Vol. 18 (1993)
Abstract: When explosives are used to initiate avalanches, inelastic deformation in immediate vicinity takes place, forming crater and region of cracks around crater. Outside this region, inelastic deformation becomes insignificant, but attenuation of stress waves still occurs. This propagation of stress waves outside crater is investigated by means of continuum theory of mixtures, which models snow as mixture of elastic solid and elastic fluid.
