Abstrakti

Estimating ship resistance in ice ridges requires an understanding of ridge failure processes. A three-dimensional discrete element method is used to study a ship passing through a small unconsolidated ridge with a triangular cross-section and the resulting velocity field and force distribution inside the ridge. The kinetic behavior of ice blocks within the ridge suggests a gradual failure process, not a sudden failure. The velocity field shows fast-moving ice blocks near the ship bow, and stationary or slow-moving blocks further away. Loads within the ridge were transmitted through force chains. No unique shear planes were observed.
