Abstract
The elastic fields associated with a dispersion of spherical particles in an isotropic matrix are determined using the equivalent inclusion approach of Moschovidis and Mura. The coherent particles possess a mis fit strain and have elastic constants different from those of the matr ix phase. A spatially nonuniform stress field can be applied to the sy stem. The stress fields are used to calculate the equilibrium composit ions at the precipitate-matrix interface for use as diffusional bounda ry conditions in computer simulations of multiparticle coarsening in e lastically stressed systems.
