A closed form solution technique is developed for predicting residual stresses after cold-expansion of a circular hole and a subsequent temperature cycle. It is assumed that the material obeys Mises' yield criterion and its associated flow rule. It is shown that the solution is very sensitive to small changes in temperature. A simple equation is derived to illustrate the variation of residual hoop stress at the edge of the hole with the amplitude of the temperature cycle. In particular, this equation shows that this stress becomes positive after temperature cycles of a small amplitude. Therefore, cracks that were stable due to residual hoop comprehensive stresses caused by cold-expansion can propagate during or after the temperature cycle.
