Ice fracture and cracks

Workshop theme

Broadly speaking, the fracture of sea ice occupies three settings: downscale (sea ice mechanics), mesoscale (the marginal ice zone, MIZ) and upscale (sea ice dynamics). At the downscale, the primary motivation is ice-structure interaction with a sea ice cover that may be deformed, discontinuous, comprised of pressure ridges, rafted ice, ice rubble and discrete ice floes.

At the mesoscale, the steady increase in the width of the MIZ (apparently caused by global warming), is unexplained by present wave-ice knowledge; the breakup of sea ice floes and aggregates of floes is the subject of intense study. At the upscale, the primary motivation is the development of continuum models of sea ice rheology suitable for inclusion within regional or global climate models, and the challenge is to accurately forecast the extent of sea ice in the Arctic (which is steadily declining), and in the Antarctica, which has recently recorded three record sea ice extents 2013-2015 (a reverse trend). At this workshop, the focus is on the roles of fracture mechanics and damage mechanics in the breakup of ice shelves, river and sea ice breakup, ice-structure indentation, FEM-DEM models, probabilistic models, crack nucleation, hydrofracture, refrozen leads, ice edge failure processes, brittle compressive failure, Coulombic faulting, and anisotropic sea ice dynamics.

This workshop will foster interactions between researchers investigation cracking phenomena at different scales and practitioners interested in explanations at different scales.
