    Abstract

    The cyclic yield strength of metals depends on the cyclic plastic deformation, the static mean stress, the number of cycles, and the frequency. For a number of different alloys, the cyclic yield strength in bending was determined as a function of the plastic deformaion and the mean stress. The application of a static stress always caused a reduction of the cyclic yield strength. The magnitude of the reduction depends on the type of material investigated. The results are discussed with respect to possible spring applications.
