Abstract (EN): Notch and size effects show significant impact on the fatigue performance of engineering components, which deserves special attention. In this work, strain energy reformulated critical distance theory was developed for fatigue life prediction of notched components under size effect. Experimental data of different notched specimens manufactured from GH4169, TC4, TC11 alloys and low carbon steel En3B were used for model validation and comparison. Results indicate the proposed model works better than the Yang's and the Shen's models.
