Abstract
This paper presents a particle-based 3D-modeling of ice-sheet break-up processes during a collision with a structure by the three-dimensional Moving Particle Simulation (MPS) method. The model considers both the ice-sheet and the pile structure as a continuum and the dynamic motion of ice is represented as a set of calculation particles. The model is verified through the comparisons between numerical results and the experiments of ice sheet break-up and failure mode around a pile structure. Quantitative investigation from the numerical results is also made, showing that the difference in the ice failure mode originates from and affected dominantly by pressure wave propagation across the ice. In addition, the model shows applicability for the prediction of impact force exerted by ice sheet collision.
