Crystal Orientation and Dislocation Slip
Metals, 2023 It is a widely held belief that dislocation slip has a direct effect on crystal orientation. Some of the confusion may be attributed to semantics when researchers are referring to related effects of dislocations on crystal orientation; either elastic ...

Plasticity of crystals and interfaces: From discrete dislocations to size-dependent continuum theory [PDF]
Theoretical and Applied Mechanics, 2010 In this communication, we summarize the current advances in size-dependent continuum plasticity of crystals, specifically, the rate-independent (quasistatic) formulation, on the basis of dislocation mechanics.
