On the restoration of strength through stress-driven healing of faults in ice

Brittle compressive strength restored to saline ice containing three different kinds of fault upon holding under normal stress of 750 kPa for up to 18 h at −10° C. Strengthening increases with time of holding but is relatively insensitive to the character of the fault. The restoration is caused by the creep of asperities in contact across the plane of the fault.94
