Comparison of shot peening and nitriding surface treatments under complex fretting loadings [PDF]

, 2006
Considered as a plague for numerous industrial assemblies, fretting associated with small oscillatory displacements is encountered in all quasi-static contacts submitted to vibrations.

‘I, Me, Myself’: Selfhood and Melancholy in the Journals of Gertrude Savile (1697–1758)

Journal for Eighteenth-Century Studies, EarlyView.
Abstract This article examines the journals of Gertrude Savile from 1727 in light of recent scholarship on early modern and eighteenth‐century melancholy. The concept had myriad associations with medicine, physiology, the imagination, and feeling, but questions remain about how melancholy during this period was considered by those outside the narrow ...

THE DANG VAN FATIGUE CRITERION OF THE FRETTING PHENOMENON [PDF]

Analele Universităţii "Constantin Brâncuşi" din Târgu Jiu: Seria Inginerie, 2019
Fretting is now fully identified as a small amplitude oscillatory motion which induces a harmonic tangential force between two surfaces in contact. It is related to three main loadings, i.e. fretting-wear, fretting-fatigue and fretting corrosion.

Review and classification of fretting fatigue test rigs [PDF]

, 2011
There is no standard or generally accepted test rig for fretting fatigue experiments. Therefore, researchers adopt an existing concept, or build a new test rig that meets their specific requirements.

Development of a Wöhler-like approach to quantify the Ti(CxNy) coatings durability under oscillating sliding conditions [PDF]

, 2005
The selection of a proper material for the particular engineering application is a complex problem, as different materials offer unique properties and it is not possible to gather all useful characteristics in a single one. Hence, employment of different

Medium‐Cycle Fatigue Behavior of Three Metallic Materials and a Welded Steel Following Gaseous Hydrogen Soaking

Fatigue &Fracture of Engineering Materials &Structures, EarlyView.
ABSTRACT This study investigates the impact of hydrogen soaking on the medium‐cycle fatigue behavior of various metallic materials commonly used in gas transmission pipelines. The tested materials include ex‐service gray cast iron, ex‐service X52 carbon steel, brass, and welded X52 carbon steel.

Effect of the model’s geometry in fretting fatigue life prediction [PDF]

Fracture and Structural Integrity, 2014
This paper analyses the influence that the type of geometry used to obtain the stress/strain fields in a cylindrical contact has on fretting fatigue life predictions. In addition, this work considers the effect that the fatigue crack shape assumed has on

Mechanics of fretting fatigue tests

International Journal of Mechanical Sciences, 1987
A popular fretting fatigue test, in which oscillating tension is applied in phase with the fretting force, is analyzed. The configuration is a generalization of the well-known Mindlin contact problem, and it is shown that the addition of bulk tension has a substantial effect on the stick- slip geometry and the shear traction at the interface.

Energetic microdomains and the vascular control of neuronal and muscle excitability: Toward a unified model

The Journal of Physiology, EarlyView.
Abstract figure legend The capillary–mitochondria–ion channel (CMIC) axis scales structural resources to match functional workload. (Left) In settings of restricted energetic capacity (e.g. cortical neurons), sparse capillary networks and modest mitochondrial pools set a lower energetic ceiling, sufficient to support phasic, low‐workload excitability.
