| Abstract | Recent model tests at the Institute for Ocean Technology (IOT) showed that the influence of shear stresses on determining failure modes during ice-cone interactions becomes more important with increase of ice velocity and is finally predominant for large cone angles and thick ice with the ice edge failing predominately in shear mode. The same shear failure mode has been observed as the dominant failure mode of freshwater ice during the ice/cone interaction experiments conducted in C-CORE's centrifuge. This paper identifies the salient features associated with the shear failure process. A simple conceptual model was proposed for future model developments. This model incorporated the concepts of non-simultaneous ice/cone contact and failure process, rotation of the ice edge and the size of the failure zone. Predictions from the model compare well with measurements from the model tests. |
