3D DEM study on the effect of ridge keel width on rubble resistance on ships
In this paper, we use 3D discrete element method (DEM) to simulate ship penetration through a non-cohesive rubble pile presenting a ridge keel. We study the effect of the pile width on the rubble resistance and the relation between the resistance records and rubble deformation. The peak rubble resis...
