Inclined dislocations in plates
Résumé
We derive the elastic field of a periodic series of straight, inclined, dislocations in a plate using isotropic elasticity for the three components of their common Burgers vector. Explicit expressions are obtained and lead to an easy formulation of spatial derivatives. The displacement field of an isolated dislocation is described asymptotically when the dislocations are distant from each other. A few numerical applications illustrate the stress fields around screw and edge dislocations. In addition, for tungsten, calculations of elastic stored energy give the equilibrium direction of the inclined dislocation as a function of the orientation of its Burgers vector.
