Abstract: | This paper investigated the interaction between an edge dislocation and a nonuniformly coated circular inclusion. Based on
the technique of conformal mapping and the method of analytical continuation in conjunction with alternating technique, the
solutions to plane elasticity problems for three dissimilar media are derived explicitly in a series form. For a limiting
case when the thickness of the interphase layer is uniform, the derived analytical solutions of this paper are reduced to
exactly the same results available in the literature. The image force acting on the dislocation is then determined by using
the Peach–Koehler formula. It is found that the combination of material constants and nonuniformity of the interphase thickness
will exert a significant influence on the dislocation force. |
