Stress distributions in an infinite elastic solid are sought when loadings are prescribed over two coplanar circular regions. Boundary conditions, which are prescribed interior and exterior to these circular regions, are mixed with respect to shear loadings and tangential displacements; the stress normal to the plane of loading is taken to be zero. The problems are reduced to the determination of the solution to infinite sets of Fredholm integral equations of the second kind. Examples are worked for the case corresponding to coplanar penny-shaped cracks with constant shear loadings applied. With the assumption that the spacing between the cracks is large as compared with their radii, the integral equations are solved iteratively.
