MULTIAXIAL STRESS-STRAIN APPROXIMATIONS FOR NOTCH FATIGUE BEHAVIORS

The use of the fatigue notch factor k sub f Neuber's rule is shown to be identical in the elastic range to the assumption of the Hookian stress concentration factor K sub t, a multiaxial stress state, and a maximum principal strain criterion for fatigue life. The adequacy of assuming the fatigue notch factor K sub f is demonstrated for mild notches. Arguments are presented in favor of assuming a multiaxial stress state at the notch for highly constrained notches.
