Abstract

Finite element modelling of the creep behaviour of a small glacier under low stresses F. Azizi," S. Jim^ & W.B. Whalley" o/ o/ ABSTRACT Knowledge of the creep properties of ice or ice-rich materials is important in a variety of geological features. Although the behaviour of large ice masses such as glaciers and ice sheets has been considered in great detail in the past decade or so and is thought to be reasonably well understood, the deformation (or rate of deformation) generated by low stresses are yet to be properly investigated. Such conditions may occur where snow patches are preserved under debris covers and may remain for many years, undergoing a slow deformation over that period of time. Similarly, the long term creep behaviour of ice-debris mixtures is little understood. This problem occurs especially where ice content of granular materials is well below saturation level, or when the debris is dispersed in thin ice masses. The paper present
