First, the displacement and elastic strain fields of an infinitesimal phase boundary disclination loop (IPBDL) and a rectangular disclination loop in a planar phase boundary (RDLPPB) are derived. Then, regarding the RDLPPB as a fundamental defect unit, the displacement and strain fields of more complex dislcination configurations are calculated. All the results are presented in the form of analytical expressions of elementary functions. All the results are simplified to corresponding expressions for a homogeneous medium when both the phases have the same elastic properties.
