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...

| Summary: | 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 + or - 2 degrees C and salinity of 4.2% the average shear strength was 550 kPa with a standard deviation of 120 kPa. On a appliqué à de la glace de mer une méthode d'essai de cisaillement faisant appel à une flexion asymétrique en quatre points. La méthode permet de réduire l'incertitude du champ de contraintes créé. Les essais ont été réalisés avec des échantillons de glace columnaire granulaire/discontinue de la mer de Beaufort. A une température de - 13 + ou - 2 degrés C. et à une salinité de 4,2%, la résistance moyenne au cisaillement a été de 550 kPa; l'écart type était de 120kPa. Peer reviewed: Yes NRC publication: Yes |
