The Creep of NaCl-Doped Ice Monocrystals
Abstract Monocrystals of ice grown from NaCl solutions (concentration 5 X 10 –4 to 10 –2 mol/l) have been tested in creep at —10°C by basal glide. The maximum resolved shear stress ranged from 0.6 to 2.5 bar. The resulting creep curves show a deceleration, that is, the creep rate decreases with time...
