The use of the high-frequency fatigue test as a method for accelerated estimation of endurance characteristics of materials

It is shown that the methods for accelerated estimation of endurance characteristics of materials involving high-frequency cyclic loading have certain advantages as compared to other “accelerated” methods. The effect of cyclic loading frequency on the endurance limit is considered for a number of metallic materials and the possibility is shown to plot a single fatigue curve independent of the number of cycles. The most promising areas of application for high-frequency fatigue test methods are noted.
