Record #125440:

The dynamic friction characteristics of a rapidly sheared granular material applied to the motion of snow avalanches / J.D. Dent.

Title: The dynamic friction characteristics of a rapidly sheared granular material applied to the motion of snow avalanches / J.D. Dent.
Author(s): Dent, J. D.
Date: 1993.
In: Annals of Glaciology. (1993.), Vol. 18 (1993)
Abstract: Numerical simulation of simple two-dimensional shear of round uniform grains is used to investigate dynamic friction characteristics of layer of snow at base of avalanche. For steady uniform flow on uniform flat surface, dynamic friction coefficient transmitted through shear array is found as it varies with shear speed and normal force applied to top of shear layer and properties of particles in shear layer.
