An index for the selection of a candidate structural material under thermal shock conditions is formulated. By an engineering approximation, the index is derived from a set of parameters which governs the solutions in thermoelasticity. In the modes of heat transfer, only the heat conduction and radiation are considered. The influence of temperature dependence of these indices is stressed. To avoid any possible misconception on the selection of the index, it is recommended that an examination of the total temperature range of interest be made. An example of a heated sphere is used to illustrate the analysis, and the derived index agrees well with the previous result.
