· 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 ...

Characterization of dislocation motion in the alloy using discrete dislocation dynamics (DDD) simulations. Video showing the effect of lattice strain field on the dynamic evolution of dislocations ...

The energy of a dislocation depends on its position in its slip plane. The diagram represents a slip plane with a position dependent potential having a period, a, determined by the location of rows of ...
