Equivalent expression is derived for an ellipsoidal double inhomogeneous inclusion which consists of a nested sequence of two inhomogeneous inclusions whose elastic constants are different both from that of a matrix and from each other. By using the resultant equivalent expression, the elastic strain energy and the total potential energy of such an ellipsoidal double inhomogeneous inclusion are formulated as a function of two equivalent eigenstrains. In addition to this, for two types of the mixed double inclusions, i.e., one is the mixed double inclusion of the first kind which is defined as an ellipsoidal inhomogeneous inclusion surrounded by an annular inclusion and the other is that of the second kind which is vice visa, equivalent expressions, elastic strain energies, and total potential energies of the system are also derived successfully.
