| Résumé | The Cambridge University has sought assistance from IOT for computer simulations of the gouging process using DECICE. The objective of this project was to study the conditions in which an ice keel will break up, partially or completely, when in contact with the seabed during the process of ice gouging. The ice friction angle and the cohesion of ice were the two key parameters investigated, as they have a significant effect on the fracture of breakable ice ridges. The data obtained from DECICE aimed to establish a relationship between the fracture of ice ridges and their mechanical properties. At the writing of this memorandum, we have only completed simulations with varying ice friction, seabed inclination and trajectory angle. This memorandum documents the results of these simulations. |
