Recent analyses of in-situ and satellite observations of arctic sea ice stresses and strain-rates revealed a highly intermittent and heterogeneous dynamics characterized by temporal and spatial scaling laws, a vision at odds with the classical smooth, fluid-like modelling framework of the sea ice cover. We propose here a simple multiscale fracturing model that explains the observed scaling properties...
The dynamical core of a new sea ice model is presented. It is based on the Elasto–Brittle rheology, which is inspired by progressive damage models used for example in rock mechanics. The main idea is that each element can be damaged when the local internal stress exceeds a Mohr–Coulomb failure criterion. The model is implemented with a finite element method and a Lagrangian advection scheme. Simulations...
