... ABSTRACT The DEM (Discrete Element Method) – FEM (Finite Element Method) coupling analyses were performed using vessels with elastic bottom plate which have various aspect ratio. In the results of the analyses whose aspect ratio of the inner bottom plate is greater than 1, the arch effect...

... ABSTRACT To evaluate the loads due to dry bulk cargoes on the inner hull of bulk carriers, this study investigates effects of the inter-particle and particle-wall frictional properties on internal pressure using Discrete Element Method (DEM) in a vessel that simulates a cargo hold...

... numerical models of layered rock samples through the discrete element method were established to study the influence of soft rock interlayer on the mechanics of the layered rock samples. The results shows that the ultimate strain and compression strength of layered rock sample mainly influenced...

... ABSTRACT Applying deformable structures in underwater environment is a hot topic in ocean development. In this study, an underwater arch-shaped deformable structure filling the swollen hydrogel beads in its flexible outer frame was proposed. Based on discrete element method, after...

... ABSTRACT Cutter suction dredger is one of the most widely used dredger types in Waterway Dredging Engineering, with the advantages of strong adaptability to complex environment and high efficiency. Based on DEM (discrete element method), this paper studies the cutting efficiency of rock cutter...

... ABSTRACT Ice load is an important factor in ship structure design and safe navigation. In view of the advantages of Discrete Element Method (DEM) in dealing with the problem of discontinuous medium, the ice resistance of ships in flat ice area is analyzed by using DEM, and the resistance...

... ABSTRACT In this Paper, I used 250K DWT VLOC as an example, the internal load of dry bulk cargoes analysis is performed in discrete element method (DEM) by means of EDEM. Study takes the actual cargo hold for simulation of sand loading condition in reasonable simulation parameters. For this study...

... sections of rubble mound structures by using Discrete Element Method. These studies mainly focus on the deformation in completed cross sections. On the other hand, there are few studies on the deformation in cross sections under construction. Aikawa et al. (2001) investigated rubble mound seawalls...
