Investigation of Residual Stress Distribution and Fatigue of 7050-T7451 Alloy Hole Components with Laser Shock and Ultrasonic Extrusion

Metals
Small-hole structures, such as the millions of fastener holes found on aircraft, are typical stress-concentration structures prone to fatigue failure.

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.

Biomechanical evaluation of natural tooth–implant splints and comparison with implant cantilevers in the anterior region under fatigue tests [PDF]

Journal of Dental Research, Dental Clinics, Dental Prospects
Background. Several methods are used to replace lost teeth. This study aimed to reconstruct pre-maxillary conditions when a limited number of implants are available and investigate the biomechanics of the two methods available to dentists for use in ...

Design of a fretting fatigue test rig with compliant springs [PDF]

, 2013
Fretting is a small amplitude oscillatory movement which occurs between contacting bodies who are subjected to cyclic loading or vibrations. In the contact area arise stresses -normal and tangential- causing stress concentrations and surface degradation.

Characterisation of a resonant bending fatigue setup for pipes [PDF]

, 2011
This paper discusses the resonant bending fatigue test setup designed at laboratory Soete for full-scale fatigue tests on pipes. Following an enumeration of other types of fatigue test setups an attempt is made to characterise the resonant bending ...

Fatigue crack growth in a laser shock peened residual stress field [PDF]

, 2019
Laser Shock Peening is a surface treatment technique used in the aerospace sector to increase fatigue life, as well as resistance to fretting fatigue and stress corrosion cracking.

Fatigue test bench manufacturing by reusing a parallel lathe [PDF]

, 2018
Fatigue life of machined parts strongly depends on their surface condition. The rotating bar bending fatigue testing method is widely used to obtain the fatigue behavior of metallic materials due to its simplicity.

The influence of stress and muscle fatigue on implicitly and explicitly learned motor skills [PDF]

, 2007
According to Beek (2000), disturbing causes at the upper level of action (i.e. stress) and at the lower level of control (i.e. muscular fatigue) might result in different effects on performance when comparing implicit and explicit learning.

Characterization of crack nucleation in TA6V under fretting-fatigue loading using the potential drop technique [PDF]

, 2010
Crack initiation in a Ti-6Al-4V alloy was investigated experimentally in fretting fatigue conditions. A cylinder-plane geometry was used for the contact, and partial slip conditions were considered.
