The three-dimensional axisymmetric elastic stresses in the intersections of hollow sphere and cylinders, subjected to torsion, tension and internal pressure, is analyzed easily and accurately by use of the indirect fictitious-boundary integral method. As a result, the influence of configuration parameters (e.g., the mean diameter ratio and the thickness ratio of hollow sphere and cylinder, and the roundness of a corner of intersection) on stress concentration is made clear. Furthermore, the other results, such as one obtained by photoelastic experiment, are evaluated by the present results.
