...DL Du Quesnay; MT Yu; TH Topper This investigation examines the variation of the fatigue notch factor with notch size for sharp and blunt notches. Analytical expressions are developed to predict the fatigue notch factor for sharp notches based on short crack fracture mechanics and for blunt notches...

...KN Smith; M El Haddad; JF Martin This study deals with the fatigue of welded components emphasizing the use of small specimen data, a general stress-strain expression, the fatigue notch factor, and the effect of residual stresses. A computer-based fatigue damage analysis for welded structures...

...EK Walker The use of the fatigue notch factor K f in Neuber's rule is shown to be identical in the elastic range to the assumption of the Hookian stress concentration factor K t , a multiaxial stress state, and a maximum principal strain criterion for fatigue life. The adequacy of assuming...

...CVB Gowda; BN Leis; KN Smith The effects of several factors which influence the magnitude and variation with life of fatigue notch factor ( K f ) are discussed in this paper. Plasticity at the roots of stress raisers is known to have the most dominant influence on the variation of K f when...
