AbstractStrength and deformation behaviour of horizontally oriented specimens of granular and columnar-grained ice were measured in the field. Cylindrical specimens were loaded on compliant platens and prismoidal specimens on steel platens to provide a range of loading system stiffness. Loading system stiffness proved to have a significant effect on strength when the results were interpreted in terms of nominal strain rate, but in terms of stress rate it was largely eliminated. The strength of the granular ice (2.5 - 4 MPa) was substantially higher than that of columnar- grained ice (1 - 2.5 MPa). Regardless of grain structure, the specimens all failed by yielding at a strain of about 3 x 10[-3].
