Effects of Tapered-Strut Design on Fatigue Life Enhancement of Peripheral Stents

open access: yesBioengineering, 2023
Peripheral stent could fracture from cyclic loadings as a result of our blood pressures or daily activities. Fatigue performance has therefore become a key issue for peripheral stent design.

Non-local energy based fatigue life calculation method under multiaxial variable amplitude loadings [PDF]

open access: yes, 2013
Reliable design of industrial components against high cycle multiaxial fatigue requires a model capable of predicting both stress gradient and load type effects. Indeed, taking into account gradient effects is of prior importance for the applicability of

Bending fatigue strength design method for machine components with complex geometries [PDF]

open access: yesFracture and Structural Integrity, 2018
The purpose of this study is to devise a bending fatigue strength evaluation method that can be widely used for any machine component under the consideration that bending fatigue breakage depends on the initiation of a surface fatigue crack, namely, the ...

Life events, difficulties and dilemmas in the onset of chronic fatigue syndrome: a case-control study [PDF]

open access: yes, 2003
Background. The role of stress in the onset of chronic fatigue syndrome is unclear. Our objectives in this study were first, to determine the relation between the onset of chronic fatigue syndrome and stressful life events and difficulties.

Numerical methods for the fatigue assessment of welded joints: influence of misalignment and geometric weld imperfections

open access: yesEngineering Structures and Technologies, 2017
The fatigue design life of welded joints in steel structures is increasingly assessed by using numerical models and methods, such as the structural (hot-spot) stress method and the effective notch stress method.

Fatigue Behavior and Mechanism Study on Lugs of TC18 Titanium Alloy

open access: yesCrystals, 2023
Aerospace structural components are in a complex stress state when they undertake load due to their specific geometric construction. Their fatigue behavior is quite different from the materials that undertake the standard stress state.

Fatigue Design Research on Notch–Stud Connectors of Timber–Concrete Composite Structures

open access: yesBuildings
To investigate the mechanical behavior and damage mechanism of notch–stud connectors in timber–concrete composites under fatigue loading, fifteen push-out specimens in five groups were designed with load cycles as the key variable.
