Nonlinear formulation of snow creep
AbstractAlpine snow is known to display nonlinear behavior in slow deformation. In this paper, an attempt is made to formulate a nonlinear constitutive relation applicable to the prediction of creep loads on structures in deep snow covers. The resulting formulation, although approximate, is the simplest the authors found to model the flow of a granular material composed of ice grains in a realistic manner. Even though the model is restricted to well-settled, well-metamorphosed deep seasonal snow, comparison of numerical predictions with snow creep pressure measurements shows that it produces plausible pressure estimates while being more flexible than a linear flow law.
