AbstractPresented in the report is a three dimensional finite element analysis of the ship-ice interaction problem using an elasto-plastic model. After investigating two types of three dimensional solid elements, the 20-noded isoparametric solid element is chosen to model the discretized sea ice cover. The failure load is obtained as the load that acts normal to the ship hull plating when the ship fractures the ice in a "ramming" mode, using incremental iterative analysis. The ice strength data utilized in the analysis is obtained from published data of laboratory tests on sea-ice, and the ship is considered as a "rigid-body" indenting ice.
