TitlePaper, 'On the plasticity of an ice crystal' by James C McConnel
CreatorMcConnel; James C (fl 1888-1891)
Date1890
DescriptionMcConnel writes: 'Two years ago in the "Proceedings of the Royal Society" was published an account of some experiments on the plasticity of ice made by Mr Kidd and myself [see PP/12/26]. We proved the oft-repeated statement, that glacier ice is not plastic under tension, to be erroneous, and, indeed, that an ordinary bar of ice composed of several crystals will yield continuously either to pressure or tension. But we found that a bar cut out of a single crystal with its length at right angles to the optic axis showed no signs of continuous stretching, even when subjected to half the breaking stress; and other experiments convinced us that an ice crystal will not change its shape under either tension or pressure applied at right angles to its optic axis.'
