Abstract
Crack initiation and propagation in saline ice were investigated in this study in an attempt to understand the processes of crack growth under low loading rates and variable temperatures. As has been previously observed in sea ice and freshwater ice, crack growth occurred in initiation/arrest increments. The energetic stability criterion of crack growth are examined and crack growth is characterized in terms of the fracture resistance-stress intensity factor K R . Salient features of this study are the development of a new fracture geometry capable of sustained crack growth over longer crack lengths and the presentation of a fracture resistance curve for saline ice.
