AbstractFlexural strength from dedicated beam tests and ramming of multi-year floes has been compared. Flexural strength of multi-year ice from beam tests indicates the strength decreases as the size of the beams increases and this is important in comparing flexural strength data from various sources. In terms of relative flexural strength; from strongest to weakest is fresh-water ice, multi-year ice and first-year sea ice. Ship ramming results provide comparative results for flexural strength, even if the absolute values are greater than would be expected given the thickness of the ice. Colder ice floes have greater flexural strength. The MV Arctic ramming tests indicate that multi-year floes in a small area can be quite variable in thickness, temperature and flexural strength.
