A brief note on the self-balanced singular elastic field caused by an edge dislocation

Four physical quantities describing the self-balanced singular elastic field caused by an edge dislocation before or after loading are obtained by using SW-integral. These quantities are directly related to mechanisms of dislocation plasticity and are compared with that of a concentrated force. An edge dislocation and a concentrated force interacting with the first stress invariant and the maximum shear stress at infinity, respectively, are also presented.
