Abstract

AbstractThe boundary integral formulation for unsteady thermal stresses in three‐dimensional quasi‐static problems is proposed. It is shown that three‐dimensional unsteady thermal stress problems can be solved easily without the volume integral by means of the thermoelastic displacement potential and the boundary‐element method. It is also shown that the time integral can be easily carried out analytically. In order to investigate the accuracy of this method, unsteady thermal stress distributions for a cube are obtained.
