AbstractThis report presents the results of model tests in both level ice and multi-year ridges with a fixed 45 degree downward breaking cone carried out at the Institute for Marine Dynamics in January 1989. The objectives were to examine the mode of failure and the resulting failure load during the ridge/cone interaction, and to conduct further tests in thick level ice to verify the velocity and thickness effects observed in a previous test program. Results from the ridge tests provide the first set of test data on downward breaking cone/ridge interaction in open literature. A theoretical model which takes into account the difference in mechanical properties between the sheet ice and the ridge is proposed. Good agreement is found between the model predictions and the measurements.
