Abstract
This study is conducted to verify the technique of fatigue limit evaluation through numerical simulation. Temperature evolution of a notched stainless steel specimen subjected to cyclic loading is simulated by elasto-plastic finite element analysis. Both amplitude of second harmonic and mean temperature rise are obtained from the temperature evolution. It has been shown that the fatigue limits evaluated from the second harmonic amplitude and from the mean temperature rise agree fairly well with the fatigue limits obtained by thermography experiment and Wohler method.
