Abstract
Frozen saturated quartz sand containing 20% moisture by weight, when deformed at -30 degrees C at various strain rates, showed various modes of behaviour such as visco- plastic, almost ideal plastic, and brittle with little plasticity with increasing order of strain rate. The values of peak strength observed for strain rates between 5 X 10[- 7] and 6 X 10[-3]s[-1] were in the range 15-42 MPa,, stress being related to strain rate by a power-law equation.
