... Identifying multiaxial fatigue cycles and the corresponding multiaxial fatigue damage parameters is the key to accurate fatigue life assessment of welded structures. The path-dependent maximum range (PDMR) cycle counting and life assessment method provides a consistent framework...

... Ratcheting behavior or cyclic mean stress relaxation can have a significant effect on multiaxial fatigue lives when compared to proportional loads of similar range. The most important feature for ratcheting simulation in cyclic plasticity constitutive models is the nonlinear kinematic (NLK...

... 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 in multi-axial...

... 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, the difficulty of the problem is increased...

... Fatigue failure of interference-fit aluminum joints has been investigated by testing several specimens geometries, conducting numerical simulations and using multiaxial fatigue theories. The experiments included center crack, edge crack and uncracked specimens, fitted with a zero load-transfer...

... This paper presents an efficient approach for predicting high-cycle fatigue crack initiation life under general multiaxial fatigue loadings. A minimum circumscribed ellipse approach is proposed for evaluating the effective shear stress amplitude and mean value throughout a complex loading cycle...

... Results from a review of energy-based criteria of multiaxial fatigue indicate that they may be divided into three groups, depending on the kind of strain energy density per cycle which is assumed as a damage parameter. They are: criteria based on elastic strain energy for high-cycle fatigue...
