Abstract: Noncontact measurement was made of the surface temperatures of steel specimens subjected to rotating bending. The temperature variation was expressed as the sum of two exponential functions with due consideration for heat transmission. The thermal energy produced during one stress cycle could be regarded to be almost constant throughout the main fatigue process and its stress dependence was found to be expressible in an exponential function of the reciprocals of the stress amplitudes. A fatigue criterion has been obtained, which agrees with the results presented by others from the standpoint of hysteresis energy dissipation, and, being applied to the notched specimens, gives a means to determine the fatigue notch factors. The calculated values have been shown to agree satisfactorily with the data in the literature.
