Description / Table of Contents:
Summary: Experiments have been carried out on the plastic deformation of thick-walled snow-ice cylinders under hydrostatic pressure as a function of pressure and temperature. At constant circumferential stress and temperature the natural strain rate of closure is a constant. This constant varies with the circumferential stress according to a sine function and is exponentially dependent on temperature with an energy of activation of 14.1 kcal/mole at an average circumferential stress of 3.1 kg/cm^2. The mechanism of the plastic flow is in agreement with a mechanism proposed previously, that is, flow between grain boundaries takes place.
