AbstractHigh-speed uniaxial compression tests were conducted in the strain-rate range 10-1-101 s-1, at -11 C, on freshwater ice and "Baltic" sea ice of mean salinity 2.4 ± 0.7 ppt. Two different testing machines were used to check for machine stiffness effects. The results showed that for both types of ice, the strength, , increased with strain rate, , consistent with a power law, = Am, where A = 8.9 and m = 0.15 for fresh water ice, and A = 6.0 and m = 0.19 for the "Baltic" sea ice. At a strain-rate of 101 s-1, the freshwater ice was a factor of only 1.3 times stronger than the sea ice. Results are compared to literature values at lower strain rates.
