Synopsis

This Volume constitutes the Proceedings of the IUTAM Symposium on 'Scaling Laws in Ice Mechanics and Ice Dynamics', held in Fairbanks, Alaska from 13th to 16th of June 2000. Ice mechanics deals with essentially intact ice: in this discipline, descriptions of the motion and deformation of Arctic/ Antarctic and river/lake ice call for the development of physically based constitutive and fracture models over an enormous range in scale: 0.01 m - 10 km. Ice dynamics, on the other hand, deals with the movement of broken ice: descriptions of an aggregate of ice floes call for accurate modeling of momentum transfer through the sea/ice system, again over an enormous range in scale: 1 km (floe scale) - 500 km (basin scale). For ice mechanics, the emphasis on lab-scale (0.01 - 0.5 m) research con- trasts with applications at the scale of order 1 km (ice-structure interaction, icebreaking); many important upscaling questions remain to be explored.

Présentation de l'éditeur

This book is the proceedings of the Iutam Symposium held in Fairbanks, Alaska, in 2000, and addresses a variety of scaling issues in ice mechanics and ice dynamics, ranging over planetary ice mechanics, ice forces on offshore structures, fracture of ice, friction, constitutive and failure modeling, ice dynamics models, as well as textural and structural transformations in the drifting ice of the polar regions. The 39 articles focus on small and large scales in the study of ice, the failure mechanics of heterogeneous media, and multi-scale statistical physics. Guidance is provided as to the range of applicability of different fracture, constitutive, and ice dynamics models, and attempts are made to link the behavior at smaller scales with successive geophysical scales. This book should be useful to researchers in ice mechanics and ice dynamics, and to those who wish to gain an overview of the subject.
