A Micromechanics Based Model for the Creep Of Ice Including the Effects of General Microcracking

  • A. C. F. Cocks

Abstract

A constitutive law for the creep response of ice during general microcracking is developed in this paper. A simple three-bar structure is introduced for uniaxial loading and used to identify the general features of the material response. The processes of crack nucleation and creep deformation of heavily microcracked material are examined in detail and a self consistent model is developed to describe the material response under multiaxial states of stress. The observed effect of hydrostatic pressure on the material response is predicted by the model.
