Simulation of a two-dimensional ice crushing processes with the Mohr-Coulomb nodal split model

Level ice poses a significant risk for ships, offshore-, and civil structures. Crushing loads are a relevant load case for different ice-structure interaction scenarios. In this paper, the new Mohr-Coulomb Nodal Split (MCNS) ice model is used for the first time to simulate two-dimensional brittle crushing loads for unconstrained and floating level ice conditions. The results of the presented feasibility study are in good qualitative agreement with previous experimental and numerical studies of various authors. Effects such as spatial variation of High Pressure Zones are accurately represented in the numerical MCNS model. The maximum achievable nominal contact pressures in the case of an ideal contact are in the range of the compression strength of the material model used. Whereas during the crushing process, a maximum of 40% of the compression strength is reached.
