Abstract: |
Recently, a description on a practicability of the Whler Curve Method for low-cycle fatigue of metals was given by the author. By the description and the low cycle fatigue test data of 16 MnR steel, it is important to show that, for low cycle fatigue of metals, such a way that a stress-based intensity parameter calculated by the linear-elastic analysis is taken to be a stress intensity parameter, S, to establish a relationship between the stress intensity parameter, S, and the fatigue life, N, is practicable. In this paper, many metallic materials from the literature are given to show that the Whler Curve Method is well suitable for low-cycle fatigue analysis of metals. |
