Abstract:

The primary result of this project are a clear understanding of the processes which initial cracks in columnar ice under typical conditions. The primary material of study was laboratory-grown freshwater ice, in which the crystals grew as long columns with diameters in the range of a few millimeters. For some fracture toughness measurements we used large single crystals of freshwater ice. Some related work has also been done on laboratory-grown columnar saline ice.
