Forecasting the high-cycle area of the metal fatigue curve by the "endurance limit angle"

This paper discusses the use of the adduced indicators of the endurance fatigue method to forecast the fatigue curve position. The coordinates of the inflection point of the fatigue curve in the high-cycle area are compared with the limit indicators of the material endurance fatigue. By investigating these limit indicators of the endurance fatigue, a procedure for forecasting endurance limit based on the usage of the curve position characteristics of the metal fatigue can be obtained.
