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.

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 ...

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 ...

Estimation of Low-Cycle Fatigue Curves of High-Strength and Welded Steel 10CrNi3MoV [PDF]
, 2019 In this work is tested applicability of the extended uniform material law for high-strength steel on 10CrNi3MoV steel and its weld. Predicted low-cycle fatigue curves differ significantly from the measurements. Despite the reported scientific effort to

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

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

Advanced Engineering Materials, EarlyView.In this experimental study, the mechanical properties of additively manufactured Ti‐6Al‐4V lattice structures of different geometries are characterized using compression, four point bending and fatigue testing. While TPMS designs show superior fatigue resistance, SplitP and Honeycomb lattice structures combine high stiffness and strength. The resulting
