“…Field tests and model scale experiments are important tools to understand the underlining physics of the ice-structure interaction process, some representative work include: Riska et al [1], Frederking [2], Suyuthi et al [3], Chernov [4], Kujala et al [5], and model tests: Huang et al [6], Jones [7,8], Aksnes and Bonnemaire [9], Woolgar and Colbourne [10], and Jeong et al [11]. Some experiments have been carried out in the Hamburg Ship Model Basin (HSVA) [12,13], including tests of cones breaking ice in layers of ice. Based on the analysis of field measurement data and test results, the ice load and ice-structure interaction process of the structure in the ice region can be obtained.…”

In this paper, a data-driven model based on the Non-smooth Discrete Element Method (NDEM) and Artificial Neural Network Method (ANN) is proposed for the computation of the ice-breaking resistance of the structure. The idea of so-called “meta-modelling”, which means establishing an Artificial Neural Network (ANN) model based on a pre-computed ice failure database to avoid the time-consuming direct resolving of the ice fracture process, was integrated in the non-smooth discrete element method (NDEM). The developed model was validated by simulating the ice-breaking process of the cone structure, and the computational results match well with the experimental ones in the literature. After that, the effects of various parameters on the ice-breaking resistance were analyzed by the developed model. It was found that the factors that have great influence on the resistance of cone structure in level ice condition are the cone angle, navigation velocity and ice thickness.
