TENSILE-STRENGTH OF MULTI-YEAR PRESSURE RIDGE SEA ICE SAMPLES

Thirty-six constant strain-rate uniaxial tension tests were performed on vertically oriented multi-year pressure ridge samples from the Beaufort Sea. The tests were performed on a closed-loop electro-hydraulic testing machine at two strain rates (10** minus **5 and 10** minus **3 s** minus **1) and two temperatures ( minus 20 degree and minus 5 degree C). This paper summarizes the sample preparation and testing techniques used in the investigation and presents data on the tensile strength, initial tangent modulus, and failure strain of the ice.
