The Confined Compressive Strength of Polycrystalline Ice
Abstract Triaxial tests were carried out on randomly oriented, laboratory-made, polycrystalline ice, between strain-rates of 10 –7 and 10 –1 s –1 and with confining pressures from 0.1 to 85 MN m –2 , at –11 ± 1°C. Below strain-rates of about 10 –5 s –1 the confining pressure has little effect, but a...
