摘要: In this paper, the versatility of discrete element method (DEM) in modelling ice-related problems is discussed and further demonstrated using results from DEM works conducted by National Research Council's Institute for Ocean Technology (NRC-IOT) a commercial code DECICE. These include wide range ice-structure ice-ship interaction current interest, i.e. ice loads on conical structures, jamming floes at bridge piers, mechanical behaviour rubble, pack stability associated forces offshore rubble exerted an inclined retaining wall, ridge keel resistance during seabed scouring, dynamic response moored drill-ship ship manoeuvring performance ice. Representative simulations each case are presented including load, motion and/or process, whichever appropriate. The DECICE were compared with experimental data found satisfactory terms accuracy...
