    Abstract

    The use of the fatigue notch factor Kf in Neuber's rule is shown to be identical in the elastic range to the assumption of the Hookian stress concentration factor Kt, a multiaxial stress state, and a maximum principal strain criterion for fatigue life. The adequacy of assuming the fatigue notch factor Kf is demonstrated for mild notches. Arguments are presented in favor of assuming a multiaxial stress state at the notch for highly constrained notches.
