The Compressive Failure of Cracked Ice on Scales Large and Small

Abstract

Experiments have established that size per se is not a factor in the compressive strength of ice, at least over the range from 10 mm to 1 meter. Irregular interfaces between ice and loading boundaries weaken ice and lead to non-simultaneous failure when the material is deformed within the regime of brittle behavior. Ice exhibits both Coulombic (under lower confinement) and plastic (under higher confinement) compressive shear faults. The study of ice has led to new physical insight into the compressive behavior of brittle, polycrystalline materials.
