¡creep and Fracture of ice
ftice creeps when loaded slowly, and fractures when loaded rapidly. This book is
Λ
|hefirst complete accountof the physics ofthecreepand fracture of ice.and their
;
iinterconnectivity. it investigates the deformation of low-pressure ice, which serves
:,
as the basis for the study of a variety of natural phenomena
-
glaciers, polar ice sheets,
?
floating ice covers, and the uppermost region of icy moons of the outer solar System.
The central argument of the book focuses on the structure of ice and its defects, and
proceeds to describe the relationship between structure and mechanical properties,
includingelasticity. it reviews observations and measurements, and then interprets
,
them in termsof physical mechanisms. Asection on creep concludes with adiscussion
pn modelingthe ductile behavior of
isotropie
and anisotropic ice in relation to theflow
5of glaciers and polar ice sheets. A section on fracture assesses ice forces on engineered
structures and analyzes the deformation of the ice cover on the Arctic ocean from the
perspective of physical mechanisms.
The book provides a road-map to future studies of the mechanics of ice by exploring its
new contexts-the behavior of glaciers and ice sheets in relation to climate change, the
datingof deep ice cores, and the projected behavior of sea ice. it also highlights how this
knowledge of ice can be transferred into an understanding of other materials, especially
the mechanical behavior of rocks, minerals, metals, and alloys, written by two experts
in the field (Duval on creep and Schulson on fracture), the book is ¡deal for graduate
Students, engineers and scientists in Earth and planetary science, and materials science.
