摘要
The measured flexural strengths of freshwater ice and sea ice have been compiled with a view towards correlating the measured results. Two thousand, four hundred and ninety-five experimentally measured data points from nineteen investigators have been used. This correlation has been done as input for a new system being developed to quickly characterize sea ice properties. The results indicate a very good correlation (r2 = 0.77) between the flexural strength (sigma(f)) and the brine volume (nu(b)) with a functional form sigma(f) = 1.76 e-5.88 square-root nu(b) where the flexural strength is in MPa, and the brine volume is expressed as a brine volume fraction. The value of 1.76 MPa for zero brine volume is in excellent agreement with the average value (1.73 MPa) measured for freshwater ice.
