Large-scale shear test of brash ice
Patil, Aniket; Zhaka, Vasiola; Sand, Bjørnar; Laue, Jan; Cwirzen, Andrzej (Peer reviewed; Journal article, 2022)A large-scale shear apparatus has been originally developed and built to test the mechanical properties of coarsegrained material. It was used to evaluate the shear behaviour of brash ice. The brash ice blocks were collected ... -
Morphology, internal structure and formation of ice ridges in the sea around Svalbard
Bonath, Victoria; Petrich, Christian; Sand, Bjørnar; Fransson, Lennart; Cwirzen, Andrzej (Journal article; Peer reviewed, 2018)The results from 3 years of comprehensive field investigations on first-year ice ridges in the Arctic are presented in this paper. The scopes of these investigations were to fill existing knowledge gaps on ice ridges, gain ... -
Numerical prediction of ice rubble field loads on the Norströmsgrund lighthouse using cohesive element formulation
Patil, Aniket; Sand, Bjørnar; Cwirzen, Andrzej; Fransson, Lennart (Peer reviewed; Journal article, 2021)An attempt has been made to predict the ice rubble field load on Norströmsgrund lighthouse by using Cohesive Element (CE) formulation. Two sub-load events were selected to validate the numerical and material model used in ... -
Physical and mechanical properties of ice from a refrozen ship channel ice in Bay of Bothnia
Zhaka, Vasiola; Bonath, Victoria; Sand, Bjørnar; Cwirzen, Andrzej (Chapter, 2020)Winter navigation in the North Sea is expanding with respect to vessel size and traffic volume. Icebreakers create routes for ice-going vessels by breaking the level ice cover. Repeated vessel passages in the fairways and ... -
Simulation of brash ice behaviour in the Gulf of Bothnia using Smoothed Particle 1 Hydrodynamics formulation
Patil, Aniket; Sand, Bjørnar; Fransson, Lennart; Bonath, Victoria; Cwirzen, Andrzej (Peer reviewed; Journal article, 2021)The repeated passage of ships through ice-infested waters create a field of broken ice pieces. The typical size of the broken ice pieces is generally <2.0 m. This area might be referred to as a brash ice field. The movement ...
