The application of recovery creep theory to the prediction of cyclic loading and heating response of a specific high temperature alloy is illustrated for four different cyclic shapes. It is shown that a satisfactory approximation to the quasi-steady state cyclic response of the material after a number of loading cycles can be obtained from a single computation by comparison with the results of cycle-by-cycle integration. The special form of recovery creep theory employed assumes isotropic hardening and therefore does not predict a symmetrical creep strain response under symmetrical stress cycling.
