Abstract
In this work, a numerical method for finding the elastic fields of inclusions in an infinite solid with arbitrary eigenstrains is presented. The method is valid, under isotropic elasticity assumptions, for an inclusion and a surrounding matrix of equal elastic constants. The method is general in the sense that it works for any particle or inclusion of arbitrary shape and any eigenstrains. In other words, the inethod is applicable to any misfit profile along the particle-matrix interface. And since the method is numerical in nature, it is capable of calculating the elaqtic fields inside and outside the inclusion; something that is not easily attainable using analytical techniques restricted further to simple particle
