dc.descriptionCRREL Report-
dc.descriptionAbstract: This report presents the first series of conventional triaxial tests carried out on columnar first-year sea ice samples obtained from the field and tested under controlled laboratory conditions using a large-capacity test machine . A total of 110 horizontal ice samples from Prudhoe Bay, Alaska, were tested on a closed-loop electro-hydraulic test machine at -10°C in unconfined and confined constant-strain-rate compression. The confined tests were conducted in a conventional triaxial cell (σ^1 > σ^2 = σ^3) that maintalned a constant ratio between the radial and axial stress (σ^2/σ^1 = constant) to simulate in situ loading conditions. The load ratios used were 0.25, 0.50 and 0.75. The strain rate or each test was constant at 10^-2, 10^-3, or 10^-5 s^-1. Data are presented on the strength, failure strain and initial tangent modulus of the first-year sea ice under these loading conditions. The effects of confining pressure, strain rate and ice structure on the mechanical properties of the ice are examined.-
