Estimation of the fatigue strength distribution in high-cycle multiaxial fatigue taking into account the stress–strain gradient effect [PDF]
, 2006 Based on the weakest link concept, a probabilistic approach in high-cycle multiaxial fatigue is developed to predict, for a given number of cycles, the probability distribution of the fatigue strength for metallic structural components. A three-parameter

The contrast of simplicity and accuracy in modeling multiaxial notch fatigue [PDF]
MATEC Web of Conferences, 2019 The fatigue assessment of notches under multiaxial and non-proportional service loading is challenging. Simple models (e.g. local strain approach based on normal stress and strain) are of poor quality for this general case of stress states and ductile ...

Two Fatigue Life Prediction Models Based on the Critical Plane Theory and Artificial Neural Networks
MetalsSince a multiaxial loading environment may lead to the fatigue failure of structures, establishing a reliable fatigue model to predict the multiaxial fatigue lives of structures has always been a concern of engineers. This study proposes a new multiaxial

Crack mode and life of Ti-6Al-4V under multiaxial low cycle fatigue [PDF]
Fracture and Structural Integrity, 2015 This paper studies multiaxial low cycle fatigue crack mode and failure life of Ti-6Al-4V. Stress controlled fatigue tests were carried out using a hollow cylinder specimen under multiaxial loadings of ?=0, 0.4, 0.5 and 1 of which stress ratio R=0 at room

Fatigue Behaviour of Welded Aluminium under Multiaxial Loading
, 2022 S.57-64 (Vol.1)Multiaxial stress states occur in many welded constructions like chemical plants, railway carriages and frames of trucks. Those stresses can have constant and changing principal stress directions, depending on the loading mode.

How to reduce the duration of multiaxial fatigue tests under proportional service loadings [PDF]
, 2006 This paper deals with a technique to transform a multiaxial stress and strain-time sequence (in service recorded) in a simplified sequence. This simplified sequence is shorter than the original one and equivalent in terms of damage and lifetime: the ...
