Abstract

This paper investigates some practical aspects related to the use of the Theory of Critical Distances (TCD) when employed to estimate notch fatigue limits. The accuracy of different formalisations of the theory was checked by using experimental data taken from the literature. This exercise allowed us to confirm that the simplest formalisation of the TCD, in which both critical distance and critical stress are material constants [1], is also the most accurate one, giving predictions falling within an error interval of about ±20%. The TCD is also accurate when applied to notches having large opening angles.
