Numerical Simulation of Sloping Structure-Level Ice Interaction Based on SPH-FEM Conversion Algorithm

摘要

SPH-FEM conversion algorithm is proposed to simulate slopingstructure and level ice interaction. This method combines the advantagesof Finite Element Method (FEM) and Smoothed Particle Hydrodynamics(SPH), which provides a new idea for the research of ice engineering. Inthis paper, we used this method to simulate the interaction of slopingstructure and level ice. Compared with the theoretical result by Croasdale3D theory, this method predicted the icebreaking force correctly.Simultaneously, it accurately simulated the accumulation process of icerubbles as the failure finite elements were replaced by SPH particles.Thus, the SPH-FEM conversion algorithm is considered an effective wayand will be used in the numerical simulations of ice structures oricebreakers.
