Stresses in spheres with concentric spherical cavities under diametral compression by three-dimensional photoelasticity

This paper presents the experimental solution of the problem of a sphere with a concentric spherical cavity under diametral compression using the three-dimensional photoelastic method and calculations of the complete stress distributions along lines of interest using Golecki's analytical series solution. The experimental procedure, the stress distributions along different lines as well as the comparison with the theoretical results and a discussion of Golecki's solution are included.
