摘要：
The paper investigates the fatigue crack/notch sensitivity by the coupled criterion of Finite Fracture Mechanics (FFM). The approach involves two parameters: the plain specimen fatigue limit, and the threshold value of the stress intensity factor range for fatigue crack growth. Useful analytical relationships are presented. The accuracy of FFM is verified by considering experimental data available in the Literature, showing the potentiality of the coupled approach to predict size effects. (C) 2019 The Authors.
