摘要：
We account for the brittle behavior of the winter sea ice cover in terms of the competition between creep relaxation and crack extension at stress concentrators; identify as Coulombic shear faults sliding lineaments that lace through the cover; and numerically model fault development in terms of scale-independent effective friction.
