Title Circular Dislocations in an Anisotropic Medium: Specific Energy and Stress Fields
Author(s) Kuznetsov S.V. (Ishlinsky Institute for Problems in Mechanics of the Russian Academy of Sciences, Moscow, 119526 Russia; Bauman Moscow State Technical University, Moscow, 105005 Russia; Moscow State University of Civil Engineering, Moscow, 129337 Russia, kuzn-sergey@yandex.ru)
Abstract A pseudodifferential operator is constructed that describes the stress field in an anisotropic medium caused by a dislocation with a variable Burgers vector.

Under the assumption bH1/2(Π,R3), analytical expressions for the energy of circular dislocations with a variable Burgers vector in an elastic medium with general anisotropy are obtained for the first time. It was found that in an isotropic medium the energy of formation of an edge dislocation and a slip dislocation is determined only by the uniform norm of the Burgers vector.
Keywords dislocation, Burgers vector, anisotropy, energy
