| Description: | Research Report Summary: The investigations on sea ice, conducted at Thule, Greenland, during February and March 1957 included: unconfined compressive strength, ring tensile strength, and flexural strength tests on simple beams for both horizontal and vertical test specimens. Additional tests were made to determine the modulus of elasticity with the simple beams in flexure. Tests were also made for creep in uniaxial compression. Although there is a high scatter of results, a dependence of strength and creep on temperature and brine volume is evident. Higher compressive, tensile, and flexural strengths, along with higher values of the elastic modulus were obtained at lower temperatures or brine volumes. The minimum creep rate decreases with decreasing temperature and brine volume. |
