AbstractInformation is presented on the failure behavior of columnar- grained ice during compressive creep and constant strain rate tests. The role of crack formation in establishing the failure condition is briefly described. Breakdown of structure is responsible for a marked change in the creep behavior of ice in the stress range of 10 to 12 kg/cm[2]. A ductile-to-brittle transition is observed at a strain rate of about 5 X 10[-3] min[-1]. The upper yield stress in constant strain rate tests is shown to increase with increase in rate of strain up to the ductile-to-brittle transition.
