Abstract
The impact of notch is one of the major problems that remain to be solved when predicting fatigue life. The zone of notch root has serious stress concentration condition. Stress field intensity (SFI) approach is an advanced volumetric method for fatigue life prediction. This paper makes further research and puts forward a modified approach based on it. A numerical example and an engineering notched specimen are analyzed by finite element approach to prove the validity of new approach. The modified SFI approach shows good fatigue life prediction and is convenient for practical use.
