Wang, C.; Ren, H.; Li, H., and Wang, J., 2015. A direct assessment method for structure strength of icebreaker based on numerical simulation.
Considering the changes of ice stress caused by strain rate of ice, a finite element method is presented to assess structure strength of icebreaker and ice failure model is based on multi-surface criterion. This paper discusses both principle of ice and ship model and presents results of structure stress in ice environment. Secondary development technology of finite element software is applied to simulate ice failure. Phenomena such as ice failure model and velocity changes of icebreaker are shown in simulation results, which show that the simulated ice loads are in good agreement with the literature results. The method presented in this paper can reflect the stress distribution of the structure and the numerical model can be applied to predict ice load and structure strength.
