Abstract:

This paper presents the results of an extensive experimental study performed with the aim of investigating the effects of temperature, size and loading rate on the fracture toughness of saline ice. The study consisted of a total of 460 3pt bend fracture specimens of three different sizes tested at three different temperatures and three different loading rates. Data trends reveal a dependency on specimen size plus a major dependency on temperature. Loading rate dependencies, which have been reported in the literature for sea ice, are evident for cold saline ice but apparently are less significant at warm temperatures.
