Research of the properties of the material ice and ice-structure interaction are important for design of ships and offshore structures, because resource extraction, transportation links and tourism move north into the Arctic. Experimental benchmark tests have been conducted within the STePS2 (Sustainable Technology for Polar Ships and Structures) group project at the MUN (Memorial University of Newfoundland) in Canada to examine the rate dependency of conical ice indenter deformation and failure behaviour in the ductile, ductile-to-brittle and brittle ice deformation regime. The final objective was to develop a baseline curve and a database indicating rate dependent changes in peak load and failure mechanism of ice cones crushing into a steel structure. Additionally temperature and crushing depth effects were examined. The paper summarizes the results, which correlate well with other available data and extends the database for conical ice test specimens.
