Evaluation of global ice load impacts based on real-time monitoring of ship motions
Nyseth, Håvard; Robert, Frederking; Sand, Bjørnar (Peer reviewed; Journal article, 2013) -
Field measurements on the behavior of brash ice
Bonath, Victoria; Zhaka, Vasiola; Sand, Bjørnar (Peer reviewed; Journal article, 2019)The behavior and properties of brash ice are important issues for the design of ice-going vessels. Heavy brash ice conditions may cause vessels to be dependent on ice-breaker assistance and time delays in the shipping ... -
Finite element simulation of punch through test using a continuous surface cap model
Patil, Aniket; Sand, Bjørnar; Fransson, Lennart (Peer reviewed; Journal article, 2015)An attempt has been made to calibrate the material model parameters of the continuous surface cap model with data from punch through tests performed in the Northern Gulf of Bothnia. An axisymmetric finite element model has ... -
Laboratory testing of compressive and tensile strenght on level ice and ridged ice from Svalbard region
Bonath, Victoria; Patil, Aniket; Fransson, Lennart; Sand, Bjørnar (Peer reviewed; Journal article, 2013) -
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 ... -
Morphologies of ridges surveyed off Svalbard and in Fram strait, 2011 and 2012 field expeditions
Sand, Bjørnar; Petrich, Christian; Denise, Sudom (Peer reviewed; Journal article, 2013) -
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 analysis of ice loads on Taraldsvikfossen dam
Seger, Andreas; Sand, Bjørnar; Arntsen, Bård; Petrich, Chris; O'Sadnick, Megan (Chapter, 2020)Static ice loads (ice actions) are a key design parameter for dams in cold climates. Since 2012,ice stresses have been measured at Taraldsvikfossen reservoir located in Narvik, Norway. Similar to earlier observations in ... -
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 ... -
Numerical simulations of shear properties of ice rubble: A shear box experiment
Patil, Aniket; Sand, Bjørnar; Fransson, Lennart (Peer reviewed; Journal article, 2013) -
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 ... -
Smoothed particle hydrodynamics and continuous surface cap model to simulate ice rubble in punch through test
Patil, Aniket; Sand, Bjørnar; Fransson, Lennart (Peer reviewed; Journal article, 2015)Recent trend in computational mechanics shows considerable development of numerical methods to simulate discrete materials such as ice rubble. Ice rubble has highly nonlinear behavior and to simulate shear properties ... -
Three years of measurements of first year ridges in the Barents sea and Fram strait
Sand, Bjørnar; Bonath, Victoria; Sudom, Denise; Petrich, Christian (Peer reviewed; Journal article, 2015)During three expeditions in March 2011, March 2012 and April/May 2013 with the Norwegian coastguard vessel “KV Svalbard”, two pressure ridges around Svalbard, one ridge in Fram Strait and three ridges in Olga strait have ... -
Time-dependent spatial distribution of thermal stresses in the ice cover of a small reservoir
Petrich, Christian; Sæther, Irina Vasiljeva; Lennart, Fransson; Sand, Bjørnar; Arntsen, Bård (Peer reviewed; Journal article, 2015)Static ice loads (ice actions) are a key design parameter for dams in cold climates. However, their theoretical description is still elusive, introducing uncertainty in design and hindering development of remediation ...
