| Abstract | The failure of high pressure zones at the interface between ice and an indenting structure is known to be accompanied by cyclic loading. This cyclic activity has been related to the dynamic nature of the deformation taking place within a layer of damaged ice at the ice-structure interface. An experimental program involving the interaction between granular, non-saline ice and a small indentor was initiated in our laboratory to provide additional information on the nature of the ice damage at that scale. This was done with a spherical indentor 20 mm in diameter and with a radius of curvature of 25.6 mm, at displacement rates of 2, 4 and 6 mm/s and for ice temperatures of –20, –10 and –2 °C. Microcracking and recrystallization textures, similar to those documented from the field, are observed, with the former becoming more abundant at low temperatures. |
