Ice ridges are one of the key concerns for the design and operation of ships and structures in ice prone areas. Little information on the flexural behavior of ridges is available. This body of research aimed to develop, calibrate, and validate a numerical tool based on data gathered during the last eight years in the Development of Ice Ridge Keel Strength (DIRKS) and the Mechanics of Ice Rubble (MIR) projects in the Centre for Arctic Resource Development (CARD) to gain a better understanding of the failure mechanism and loads arising during flexural failure of ice ridge. The flexural failure of an ice ridge is dependent on the failure of its consolidated layer and of its keel. This requires an understanding of not only the properties and modes of failure of these two layers but also the strength of the freeze-bonds between the submerged ice blocks of the keel. A new model for the 3D DEM modeling of ice was developed and implemented in an open-source codes WooDEM and LIGGGHTS. This ice model contains normal, ...
