AbstractIn this review the results of laboratory experiments on the plastic deformation of ice are presented from the engineering point of view. A discussion is also presented on the creep behaviour of columnar-grained and snow ice in tension, compression, bending and shear emphasizing the effect of the crystal structure. The relationship between strain rate epsilon[.], creep time, stress sigma and the temperature are represented by the simple expression epsilon[.] = Asignma[n] where the factors A and n are functions of the creep time and temperature. To illustrate the significance of the deformation history on the creep properties of ice, information obtained in repeated loading tests is presented. The effect of variable stress as well as non-uniform and complex stress fields on the plastic deformation process is briefly reviewed.
