Recording the proceedings of the IUTAM Symposium held in Fairbanks, Alaska, in 2000, this book 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 modelling, and 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 behaviour 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.
