Query: The vacancy - edge dislocation interaction in fcc metals: a comparison
  between atomic simulations and elasticity theory   The interaction between vacancies and edge dislocations in face centered
cubic metals (Al, Au, Cu, Ni) is studied at different length scales. Using
empirical potentials and static relaxation, atomic simulations give us a
precise description of this interaction, mostly in the case when the separation
distance between both defects is small. At larger distances, elasticity theory
can be used to predict this interaction. From the comparison between both
approaches we obtain the minimal separation distance where elasticity applies
and we estimate the degree of refinement required in the calculation. In this
purpose, isotropic and anisotropic elasticity is used assuming a perfect or a
dissociated edge dislocation and considering the size effect as well as the
inhomogeneity interaction.
