TL;DR: In this article, the authors used critical distance concepts that employ the stress distribution in the vicinity of the notch for predicting the high cycle fatigue (HCF) lives of notched cylindrical Ti-6Al-4V specimens.

TL;DR: In this article, the authors investigated the high cycle fatigue behavior of cylindrical specimens having three sizes of geometrically similar circumferential V-notches, each with an elastic stress concentration factor, K t, of approximately 2.78.

TL;DR: In this article, a new approach, which uses the Findley critical plane damage parameter along with the stress gradient at the notch, was developed for predicting notched HCF life.

TL;DR: Weakest-link models for the prediction of the HCF limit stress of notched components were investigated in this article, where surface area elements in the high-stress region surrounding the root of a notch were employed.

TL;DR: In this article, a critical distance method for predicting the fatigue limit stresses of notched specimens was implemented for cylindrical specimens with a wide range of notch dimensions, and the experimental data were used in combination with finite element solutions for all specimen geometries to determine a "critical distance", a quantity or parameter determined from the stress distribution surrounding the notch in addition with fatigue limit stress data from unnotched specimens.
