Abstract

This paper presents a three-dimensional combined finite-discrete element model capable of describing a process of an ice sheet failing against an offshore structure. The ice sheet is consists of polyhedral rigid discrete elements joined by a lattice of Timoshenko beam elements that undergo cohesive softening upon ice failure. Contact model for discrete elements considers inter-particle friction and local ice failure. A validation study, where an ice sheet is pushed against an inclined plane, is presented. Modelled and experimental failure processes show convincing agreement. © 2023 Lulea University of Technology. All rights reserved.
