Abstract: This paper gives the results of ring tensile strength tests of lake and sea ice. The sea ice tested was normal, low-salinity, and high-salinity sea ice. The strength results plotted against the square root of the brine volume gave a least squares equation σ = 28.15 - 58.38 𝑣^½ for 𝑣^½ less than 0.400. The data show that for 𝑣^½ greater than 0.400 the strength remains constant at σ = 6.70 kg/cm^2. A series of tests was conducted to test the theory that the concentration factor, K, for a solid cylinder is equal to 6. The average of the new K values computed from the test results is 5.2.
