Abstract: A review of strain rate sensitivity of uniaxial compressive yield strength of polycrystalline ice indicates that the results obtained by different investigators reflect the stiffness of the corresponding test systems. It is shown that the softer the system the softer is the effective response of the material. Using the concept of failure modulus, it is shown that brittle-like splitting failures do not indicate pure elastic loading conditions, and that apparent ductile-to-brittle transition depends on the response of the test system. Thus, much of the scatter in available results for the same type of ice is attributable to differences in the response of the different test systems.
