“…However, for the investigated experimental configuration, a significant improvement on the estimated fatigue life by using a tensile-based approach is not expected. This is suggested by the very similar fatigue lives obtained by Araújo and Nowell [26] using averaged values of the Fatemi−Socie and Smith−Watson−Topper parameters.…”

ABSTRACT. This work presents a methodology for fretting fatigue life estimation based on the evaluation of a multiaxial fatigue parameter at a critical distance below the contact surface. The fatigue parameter is defined using the Modified Wöhler Curve Method together with a measure of shear stress amplitude based on the Maximum Rectangular Hull concept. To apply the approach in the medium-cycle fatigue regime, the critical distance is assumed to depend on the fatigue life. Available fretting fatigue experiments conducted on a cylinder-on-flat contact configuration made of Al-4%Cu alloy were used to evaluate the methodology. Most of the fatigue life estimates were within factor-of-two boundaries.

“…This was achieved by using the characteristic stress in conjunction with Miner's rule and the plain material S-N curve. Furthermore, the accuracy of the TCD for the fatigue assessment of welded joints (Taylor et al 2002), under multiaxial stress conditions (Susmel 2004) and for fretting fatigue problems (Araujo et al 2007) has also been verified.…”

Recent studies have found that stringer-to-cross-girder connections in riveted railway bridges are susceptible to fatigue cracking. Fatigue damage in these connections is caused by secondary, deformation induced effects. These effects are difficult to interpret in terms of a single, applied stress descriptor, which is customarily used in an S-N assessment. In order to address this problem, and, following the work published recently by the authors (Imam et al. 2006(Imam et al. , 2007, in this paper the results of a global-local finite element analysis of a riveted railway bridge are used within the context of the theory of critical distances (TCD). Here, using the TCD in the way proposed by Taylor (Bellett et al. 2005), fatigue damage is shown to converge upon mesh refinement. Comparisons of the TCD-based method with its more traditional, detail-specific S-N counterpart, reveal that the latter can underestimate fatigue damage in some cases by a factor of 3.5.
