Abstract
The paper discusses the micromechanical deformation and fracture processes in ice under sustained loading and their relationship with observed macromechanical processes which define the forces which moving ice can exert on a stationary structure. Using reference stress concepts, originally developed for metallic structures operating at high temperatures, it is possible to directly relate the behaviour of an ice sheet or ice mass with uniaxial compression tests. The theory is necessarily approximate, but allows a simplified overview of the behaviour in terms of standard plasticity solutions.
