The Deformation of Snow in Terms of a Structural Mechanism.

摘要

In this paper a one-dimensional theory is developed to describe the deformation of snow. This theory considers the deformation process in snow in terms of intergranular and intragranular deformations. These two components of deformations are further considered in terms of their elastic and inelastic components. As part of this development, the nature of acoustical emissions in snow is defined. This definition is then applied to include acoustical emission data in the constitutive law. A comparison between theoretical and experimental results shows good agreement.
