Abstract
Second-year columnar-grained sea ice with orthotropic texture and fabric has been tested in the field in the High Arctic under confined compressive loading conditions. Both load and confinement were applied in the plane at right angles to the long axis of the columnar grains. Axial and confining loads were measured along with the measurements of axial and lateral strains. The confinement increases the strength considerably but significantly decreases the rate sensitivity of strength. The confined strength of this sea ice has been found to be comparable to the confined strength of laboratory-made fresh water columnar-grained ice tested under ideal conditions. The investigation showed that reliable and fairly sophisticated strength studies can also be carried out in the field.
