Measurement of shear strength of granular/discontinuous-columnar sea ice

A method of performing shear tests using asymmetrical four-point bending was applied to sea ice. The method leads to less uncertainty in the stress field created. The tests were performed on specimens of granular/discontinuous-columnar ice obtained from the Beaufort Sea. For a test temperature of −1...

Zusammenfassung:A method of performing shear tests using asymmetrical four-point bending was applied to sea ice. The method leads to less uncertainty in the stress field created. The tests were performed on specimens of granular/discontinuous-columnar ice obtained from the Beaufort Sea. For a test temperature of −13 ± 2°C and salinity of 4.2%, the average shear strength was 550 kPa with a standard deviation of 120 kPa.
