AbstractUniaxial compression tests were performed on laboratory-made polycrystalline ice at an octahedral stress of 0.1 MPa. Temperatures of the fluid surrounding the ice were closely controlled (variation <0.005°C) and ranged between −5°C and −0.01°C. All tests were run until strain rates passed through a minimum value (secondary strain) and one test at −0.5°C continued in tertiary strain, with an approximately constant strain rate to 22% total strain. Values of secondary strain rate were found to increase rapidly but smoothly as the melting point was approached with a six-fold increase in strain rate between −0.1°C and −0.01°C.
