A Finite Element Method to Simulate Ice Based on Multi-Surface Failure Criterion

Abstract:

A finite element method is introduced to simulate ice failure based on multi-surface criterion. The effects of porosity, temperature and strain rates on the ice mechanic property are taken into consideration. The main principle to simulate environment is explained. Through second developed to the finite element software, the process of ship-ice interaction is simulated. And the ship motion, ice force and ice failure mode are predicted by this method. The result is compared with other papers. the numerical simulation phenomenon is nearly same with the actual process. It suggests that simulation is reasonable, and the model has potential value in simulations of assessing ship strength. The fatigue damage is pointed out to be a special problem in ice-going ship design.
