WP2 - Material Modeling

Goals:

To provide constitutive models for ice rubble (ice ridges) and permafrost that can be used in advanced analyses of boundary value problems in other WPs, and to create numerical models that could be used to predict the drift of sea ice and icebergs in the  Barents Sea and Kara Sea.

Sea Ice

Background:

The following gaps need to be addressed in order to reach the above goals: 1) Experimental observations of time and confinement effects in ice rubble as a function of the properties of freeze-bonds and ice blocks; 2) A macro scale (continuum) model for ice rubble that accounts for time effects (rate of loading and creep); 3) An effective stress based permafrost model based on thermo-hydro-mechanical (THM) principles including time effects (creep); Probabilistic estimates of icebergs and pack ice occurrence in regions of offshore development.
