| Abstract: | Numerical simulation of collision of icebreaker with ice is investigated with FEM method in this paper. Key issues during the simulation are undertaken, such as impact procedure, calculation of ice buoyancy etc. Simulation of an icebreaker during collision with ice is conducted as an illustrative example and structural strength is accessed. In summarize, the method proposed in this paper is of great significance for strength evaluation of icebreakers. |
