Solutions for stress distributions in hollow spheres undergoing radial and temporal changes in temperature are presented in a systematic and straightforward manner for use by practicing engineers. Nine types of thermal boundary conditions are considered, including insulated surfaces, convection on the boundaries, and sudden heating or cooling as would occur in thermal shock. These transient stresses may be brief and decay rapidly as the temperature gradient decreases and a contraction or expansion of the surface layer of the sphere is permitted. However, stress levels could be sufficient to produce a permanent set in the material causing residual stresses to be present when the sphere has reached thermal equilibrium. Sample results are presented.
