The influence of defect on fatigue resistance of components is carried out by using a propagation threshold approach to estimate the high cycle fatigue resistance of components from data of intrinsic properties of the material. The Chapetti's threshold curve for fatigue crack propagation is used, which includes the short crack regime. The approach accounts for the effective driving force applied to the crack as the difference between the total driving force applied to the component, ΔK, and the threshold for fatigue crack propagation of the material, ΔKth. Application to analyze the influence of plate thickness on fatigue resistance of welded joints is presented.
