Abstract
A study was made of the relation between the theoretical stress concentration factor, Kt, and the fatigue notch factor, Kf. A relation for Kf is given in terms of Kt, the root radii of the notched and unnotched specimens, and the diameters of the notched and unnotched specimens, deduced from the “highly stressed volume” analysis considered in another paper(1)*. A study of available experimental data indicated that the statistical scatter of values of Kf was large. A region based on the proposed relation for Kf and a ±10 percent scatter band included 78 percent of the data examined, 112 determinations of Kf from rotating bending experiments. The relation for Kf, based only on the geometry of the members, is proposed as a simple adequate relation for use in design.
