• The strength in low cycle fatigue of a high speed rotating disc, caused by the repeated start and stop of rotation, was experimentally studied by using aluminium and brass discs. Results of the disc-test were compared with those of the uniaxial push-pull fatigue test conducted under the same loading condition as that in the most highly stressed region of the disc. There was no good coincidence between them. However, the prediction of the fatigue life of the rotating disc based on the push-pull test values falls on a safety side. Results oft he disc-test were also examined with a theory of cyclic creep deformation of a disc presented by the authors. The critical number of cycles corresponding to the start of unstable cyclic creep deformation was found to be pretty larger than the number of cycles to fracture of the disc obtained by the experiment.
