Infinite Anisotropic Medium Reinforced by Isotropic Elliptical Ring under In-Plane and Out-of-Plane Shear Loads.

The analysis of isotropic medium stiffened by an elliptical ring has been performed by authors recently. In order to consider the influence of an anisotropy of the medium, this paper presents the analytical solutions for both in-plane problem and out-of-plane shear problem by means of combination of Leknitskii's anisotropic theory and Muskhelishvili's isotropic theory. Lastly, the multilayered rings are to be considered only in out-of-plane problem.
