The possibility was considered of describing the core of a dislocation by using a distribution of infinitesimal dislocations that was smooth enough to remove all singularities. It was concluded that the results could be quite simply extended so as to treat the case of anisotropic elasticity, and could be used to calculate contrast effects accurately. It was shown that precipitation at dislocation cores could produce a glissile-to-sessile transformation.
