Abstract

This paper presents an asymmetric elasticity solution for the stresses in a half-space containing a prolate spheroidal inhomogeneity, when it is subjected to a uniform shear eigenstrain. The interface between the inhomogeneity and the surrounding matrix is assumed to be perfect bonding or sliding. Papcovich-Neuber displacement potentials are used in the analysis. Numerical examples are given for some different major semiaxes and shape ratios, and the stress distributions around the inhomogeneity are shown graphically.
