AN ANALYSIS OF THE SMALL-SCALE STRENGTH TESTING OF ICE

The inadequacy of small-scale strength test results for the prediction of ice sheet strength is recognized. Certain patterns appear in these test results which suggest that the plasticity of the individual crystal is a controlling factor. It is found from previous investigations that ice crystal plasticity is dominated by basal glide, and that the stress-strain-time properties have the characteristics of strain softening. A stress-strain-time relation is proposed which best matches the reported results. This relation is used in analytical models which treat the small-scale sample as an assembly of grains. (Author)
