| Summary: | With the increasing hydrocarbon exploration and exploitation activities as well as ship transport in the arctic region. The ice-structure interaction has received increasing attention. In this paper, the Smoothed Particle Hydrodynamics (SPH) method is extended to simulate the ice-structure interaction and investigate the ice-induced loads and vibrations of cylindrical structure. The softening elastoplastic model integrating Drucker-Prager yield criterion is embedded into the SPH method to simulate the failure progress of ice. The cylindrical structure is conducted as the deformable material, which displacement response and ice loads during the interaction of ice and structure are investigated in this paper. In addition, a simple and effective boundary condition for modeling the interface between ice and structure has been implemented in the SPH framework to simulate the ice-structure interaction. The proposed SPH method is employed to simulate level ice interacting with a vertical narrow structure, and the numerical data is validated through comparing with experimental results. |
