Effect of Porosity on the Hydrostatic Compression of Ice,
Abstract
A cathetometer was used in conjunction with a window-equipped pressure chamber to measure linear deformation in porous polycrystalline ice samples compressed hydrostatically at pressures of up to 0.31 kb. Tests show that a porosity as little as 1% can increase the compressibility of ice four- or fivefold. However, the compression is of a substantially nonelastic nature, since very little recovery (expansion) occurs during and following pressure release. Pore closure, which is virtually complete at the higher pressures, can be attributed to a combination of plastic and cataclastic deformation of ice in the walls of the pores.
