A semi-analytical lattice-statics model was used to calculate the lattice distortion, due to an edge dislocation in a crystal lattice, to any desired degree of approximation. The edge dislocation was created by introducing a half-plane of vacancies. The defect space was decomposed into a part that had translational symmetry, and a localized end space. The displacement field in the translationally symmetrical part was calculated in terms of a constant Kanzaki-force that was related to the Burgers vector. The Dyson equation for the defect Green’s function was then solved by using a matrix-partitioning technique in the localized end-space.
