It is known that most engineering materials contain some defects in the form of cracks, voids, or inclusions. As an example, for various metals, the size, shape, and distributions of microdiscontinuities have been investigated 1,2. To evaluate the defects on the strength of structures, it is fundamental to know the stress concentration of elliptical and ellipsoidal inclusions because they cover a lot of particular cases, such as line, circular, and spherical defects. In the previous studies, an ellipsoidal inclusion has been studied by several researchers 3,4,5,6. Also, interactions among elliptical, and ellipsoidal inclusions have been discussed 5,6,7,8,9,10,11,12,13,14. Several elasticity problems involving a half-space with a spheroidal inclusion have been studied by Tsuchida et al. 15,16,17,18...
