Discrete Element Simulation of the Resistance of a Ship in Unconsolidated Ridges
Resistance on a ship penetrating a sea ice ridge is a key design parameter of ice breaking ships. The resistance of a ship in an unconsolidated ridge has been studied by using a three dimensional discrete element method. Ridges of equal thickness but different widths were used and it was observed th...

Resistance on a ship penetrating a sea ice ridge is a key design parameter of ice breaking ships.
