An elastic layer which was perfectly bonded to an elastically dissimilar substrate was considered for the case where an edge dislocation of arbitrary orientation was present in the layer or in the substrate. The resultant solution included the complete stress field, which was needed for the solution of crack problems, and the Peach-Koehler force.
