Abstract
This study was made to understand the thermal stress response of rocks subjected to heating and cooling and to help determine the feasibility of breaking rocks by high-energy surface heating. A theoretical analysis to obtain transient temperature and stress distributions in an elastic, homogeneous, and isotropic sphere subjected to arbitrary local axisymmetric heating followed by cooling over the entire surface is presented. Numerical results of the analysis are given for a typical brittle solid for the case of constant heat flux heating over the hemispherical surface followed by different rates of surface cooling.
