A mechanism for crack nucleation in saline ice is presented, by considering a planar array of hexagonal grains containing the brine pockets as a model of poly crystalline saline ice. It is shown through a thermodynamic analysis that important local s

Computer-generated models of metallic glass alloys are explored to exhibit the short-range order of their atomic structure. Binary alloys Pd-Si, Fe-P, and Fe-B are studied as a function of composition. Several approaches are used. The distribution of

This short paper presents an alternative model for the velocity of kinks on a dislocation in an ice lattice to that presented by Whitworth, Paren and Glen (1976). The physics of the two models is identical; but they involve quite different methods fo

The mechanisms by which ice can deform are described and extended. Some, like proton-rearrangement controlled glide, are unique to the structure of ice; others, like diffusional flow, are identical...

In order to provide a suitable background for this subject, a brief account of some of the salient features of its history is necessary (Silsbee 1949). Although electrostatics is an ancient science, electromagnetism and hence electrical engineering w

A computer model was used to calculate the shape and average velocity v of a dislocation acted on by a viscous drag, and moving through a field of point obstacles. As a special case, the operation of a Frank‐Read source was computed also. At suffic

The construction of deformation-mechanism maps for ferrous alloys is described. Maps for pure iron, 316 and 304 stainless steel, and a ferritic 1 percent Cr-Mo-V steel are presented, and their use is illustrated. The maps are constructed, as far as p

A crystalline solid can deform plastically in a number of ways. Deformation mechanism diagrams can be constructed which show the fields of stress and temperature in which a given mechanism is dominant and the strain- rate that it yields. This second
