Strength and deformation of frozen saturated sand at -30 degrees C
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...
