The contrast of simplicity and accuracy in modeling multiaxial notch fatigue [PDF]

open access: yesMATEC 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 ...

Estimation of the fatigue strength distribution in high-cycle multiaxial fatigue taking into account the stress–strain gradient effect [PDF]

open access: yes, 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

A multiaxial fratigue life criterion for non-symmetrical and non-proportional elasto-plastic deformation

open access: yes, 2022
S.383-400A new low-cycle multiaxial fatigue life prediction methodology based on the concept of an effective shear strain is proposed. This effective shear strain is derived by averaging the total shear strains acting on all planes passing through a ...

A new approach to model the fatigue anisotropy due to non-metallic inclusions in forged steels [PDF]

open access: yes, 2012
The objective of this work is to propose an anisotropic fatigue criterion for the sizing of industrial forged components. The results from different experimental campaigns using three different rolled steels are first presented.

Two Fatigue Life Prediction Models Based on the Critical Plane Theory and Artificial Neural Networks

open access: yesMetals
Since 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]

open access: yesFracture 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

How to reduce the duration of multiaxial fatigue tests under proportional service loadings [PDF]

open access: yes, 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 ...

The effect of quenching and defects size on the HCF behaviour of Boron steel [PDF]

open access: yes, 2014
This work investigates the effect of natural and artificial surface defects and quenching on the fatigue strength of a Boron steel (22MnB5). A vast experimental campaign has been undertaken to study the high cycle fatigue behaviour and more specifically ...

Multiaxial high-cycle fatigue modelling for random loading [PDF]

open access: yesMATEC Web of Conferences, 2019
In this paper, a multiaxial fatigue life prediction model is proposed under general multiaxial random loadings. First, a brief review for existing multiaxial fatigue models is given and special focus is on the LiuMahadevan critical plane concept, which ...
