  1. 1. Nonlinear Numerical Simulations of Interactions Between Ice Rubble and Structure

    Författare :Aniket Patil; Andrzej Cwirzen; Björnar Sand; Lennart Fransson; Knut Vilhelm Høyland; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ice mechanics; ice rubble; sea ice ridges; punch through test; shear box test; friction coefficient; cohesive element method; smoothed particle hydrodynamics; continuous surface cap model; numerical modelling; Byggkonstruktion; Structural Engineering;

    Sammanfattning : This research is focused on three distinct but interconnecting topics:1) investigation of physical and mechanical properties of ice rubble, 2) material modelling of ice rubble, 3) numerical simulation of the interaction between ice rubble structure interaction. large scatter in the values of physical and mechanical properties of ice rubble can be seen in the literature due to non-standardised methods.
