We present a MATLAB code that evaluates the quasi-static elastic displacement strain and stress fields for the ellipsoidal inclusion and heterogeneity, the Eshelby solution. We first give an introduction to the underlaying inclusion problem.

The outcome of the study is two shape factors, one for the elastic strain energy and the other for the interface energy. heartworm medication online australiaWebEshelby started with a thought experiment on the possible stress, strain, and displacement fields in a linear elastic body containing an inclusion.
