Compressive strength of natural sea ice in horizontal loading
Samples of natural sea ice obtained from shorefast ice were loaded in compression, in the horizontal direction, both parallel and perpendicular to the C-axis, at a constant strain rate of 10 power in -3 sec power in -1. The average compressive strength parallel to the C-axis was 7.23 MPa at 10°C and...

Summary: | Samples of natural sea ice obtained from shorefast ice were loaded in compression, in the horizontal direction, both parallel and perpendicular to the C-axis, at a constant strain rate of 10 power in -3 sec power in -1. The average compressive strength parallel to the C-axis was 7.23 MPa at 10°C and 6.77 MPa at -20°C. This is in fair agreement with published values; the smaller strength at 20°C is attributed to the formation of internal microcracks upon thawing of the sodium chloride dihydrate in the brine inclusions, and the annealing of the microcracks prior to testing at the higher temperature. |
