Temperature effect on the uniaxial strength of ice
This work discusses the effect of temperature on the uniaxial strength of fine-grained, polycrystalline ice. Dumbbell-shaped specimens were loaded in uniaxial compression and uniaxial tension. Two machine speeds, 0.847 mm/sec and 84.7 mm/sec were used for the tests and the test temperatures ranged from -0.1 to -54 C. The uniaxial compressive strength is very sensitive to temperature, but did continue to increase with decreasing temperature. The tensile strength increased the most between -0.1 and -3 C. An initial tangent modulus and a 50% stress modulus were found for each compression test. The initial tangent modulus increased approximately 2 times as the temperature decreased from -0.1 to -54 C. The 50% stress modulus also increased with decreasing temperature. A secant modulus was found for the tensile tests and it tended to decrease with decreasing temperature. The specific energy required to cause failure also was found for the compression and tension tests. 17 references.
