...Gaëlle Leopold; Yves Nadot An experimental database containing multiaxial fatigue results for C35 steel with induced defects has been previously published [Billaudeau, T., Nadot, Y., and Bezine, G., “Multiaxial Fatigue Limit for Defective Materials: Mechanisms and Experiments,” Acta Mater., Vol. 52...

... gradient effect issue. A new non local multiaxial fatigue approach is proposed and applied to rotating bending and fretting experiments. The proposal takes as a starting point the rotating bending results and stress gradient analysis of a cylinder-plane contact in partial slip sliding regime. Both weight...

...H Desimone; A Bernasconi; S Beretta The fatigue strength assessment of parts subjected to rolling and sliding contacts is a multiaxial fatigue problem because of the cyclic variation of the six components of the stress tensor, which generate non proportional stress paths. In real steels...

...P Dong; JK Hong In this paper, the applicability of a new mesh-insensitive structural stress method is examined for the evaluation of multiaxial fatigue behaviors in welded joints. The mesh-insensitive structural stress method proves to be effective in characterizing stress concentration effects...
