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