AbstractDuring the course of experiments on crack formation in ice subject to a constant compressive load, some information was obtained on the deformation mechanisms that occurred. It is the purpose of this paper to describe these mechanisms, relate them to similar observations that have been made on ice and other materials, and discuss their significance with respect to the deformation behavior of ice. This will be done in four sections. The first section contains a description of the ice and the experiments. In the second section the deformation mechanisms observed are described and discussed briefly. The response of a grain to the applied load and the role that the deformation mechanisms play in determining this response are discussed in the third section. Finally, deformation mechanisms are discussed with respect to the observed creep behavior, and some generalizations on the behavior of ice in certain engineering problems are presented.
