Abstract
An analysis has been performed to calculate the uniaxial compressive strength of first-year sea ice sheets in the Canadian Beaufort Sea. The analysis makes use of a recently-developed model by the authors. It was found that the ice sheet reaches a maximum strength in March/April of each year. At that time typical strength values are 4.5 MPa, 1.5 MPa and 0.5 MPa at strain rates of 10-3 s-1, 10-5 s-1 and 10-7 s-1. In general, the strength values for the sea ice are reasonably consistent throughout the Beaufort Sea region, regardless of the severity of the winter. The information supplied in this paper should provide the design engineer with useful information on the strength properties necessary for designing offshore structures in this region.
