PROCESS OF FAILURE IN ICE

Information 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/sq cm. A ductile-to-brittle transition is observed at a strain rate of about 0.005/min. The upper yield stress in constant strain rate tests is shown to increase in rate of strain up to the ductile-to-brittle transition.
