The green circle outlines a group of atoms close to the dislocation line that have larger displacements (local strains) than permitted in a continuum model of the material ... Continuum elasticity ...

Dislocation motion in crystals can occur when a shear stress act across the slip plane. This is illustrated for an edge dislocation. · The atomic structure is only adjusted in the region of the ...

This tool has also been useful in investigating the behavior of dislocations. Since the bonding of the bubbles is analogous ... forces are similar to those of systems with metallic bonding, the bubble ...

If the slip in alternate cycles were exactly reversed in the same atomic planes ... some mechanism such as that proposed by Mott 2 the dislocations which have moved in one direction along a ...
