Review of Multiaxial Testing for Very High Cycle Fatigue: From ‘Conventional’ to Ultrasonic Machines
Machines, 2020 Fatigue is one of the main causes for in service failure of mechanical components and structures. With the development of new materials, such as high strength aluminium or titanium alloys with different microstructures from steels, materials no longer ...

New Criterion for Aircraft Multiaxial Fatigue Analysis [PDF]
MATEC Web of Conferences, 2019 The complexity of analytical and experimental estimation of aircraft components fatigue life is determined by the irregular character of the load’s sequence, a number of stress concentrators, multiaxial stress state.

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 ...

Multiaxial fatigue behavior of SLM Ti6Al4V alloy under different loading conditions
Fatigue & Fracture of Engineering Materials & Structures, 2021 The multiaxial fatigue behavior of Ti6Al4V samples, made by selective laser melting (SLM) process, was investigated in this work. Fatigue tests were carried out under three different loading conditions: (i) tensile, (ii) torsion, and (iii) in-phase axial

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

A review of multiaxial low-cycle fatigue criteria for life prediction of metals
International journal of damage mechanicsMost of real-world structural components that undergo cyclic loading feature multiaxial fatigue. When the cyclic loading involves also significant plastic deformation, multiaxial low-cycle fatigue takes place.
