Abstract
We establish the uniformity of stresses and strains inside an imperfectly bonded elastic ellipsoidal inhomogeneity embedded within an infinite elastic matrix subjected to uniform remote stresses and strains. Both the inhomogeneity and the matrix can be either isotropic elastic or generally anisotropic elastic. The imperfect interface is described by a spring-type imperfect interface characterized by a single imperfect interface function. The same degree of imperfection of the ellipsoidal interface is realized in both the normal and tangential directions. We identify the imperfect interface function leading to an internal uniform field. The internal uniform strains and stresses within the ellipsoidal inhomogeneity are obtained with the aid of Eshelby’s equivalent inclusion method.
