| Abstract: | Strength results of laboratory-grown NaCl and urea-doped columnar-grained ice as well as first-year sea ice were analyzed with respect to dependencies on strain-rate, temperature, density, and dopant concentration or salinity. Uniaxial and biaxial compressive strengths and uniaxial tensile strengths are considered at strain-rates from 2x10⁻⁶ s⁻¹ up to 1x10⁻² s⁻¹ and in temperature range from -15 to -5°C. Improved model for sea-ice strength is established in which total porosity is governing parameter. Reference strengths are evaluated for ductile and brittle regime representing strength characteristics of imaginary bubble-free columnar grained ice at 0°C under various load orientations and conditions. Shows that reference strengths are independent of total porosity, strain-rate, temperature, and dopant type. |
