Gradually increasing amplitude
-
Fatigue curve presents the relation between stress (mean stress, maximum stress or stress amplitude) and the number of stress cycles till a machine element is completely broken. This curve is served as the important basis of design as well as lifetime prediction for machine elements. In order to create a fatigue curve, the traditional fatigue test method is applied to specimens using a cyclic stress with constant amplitude.
