The double torsion test applied to fine grained freshwater columnar ice, and sea ice
The Double Torsion fracture test geometry has been applied to samples of fine grained fresh water ice grown in the cold room, and to first year sea ice tested in situ at 74°N. The lab ice was grown at -20°C from a wet seed, and sample dimensions of 0.05m × 0.5m × 1.0m were used for both ices in the...
