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.

Variable mode-mixity during fatigue cycles – crack tip parameters determined from displacement fields measured by digital image correlation [PDF]
Fracture and Structural Integrity, 2017 This paper focusses on discussing equivalent stress intensity factors and kink angles after a change of mode-mixity from one cycle to the next and when the mode-mixity changes continuously during the fatigue cycles.

Observations and modelling of non-proportional mixed mode cyclic loading [PDF]
MATEC Web of Conferences, 2019 Under non-proportional mixed-mode loading conditions at the crack tip, some observations are reported. They are limited to cases of cylindrical specimens under normal force and torsion. The fatigue cracks have been initiated by the same loading for which

Fatigue growth rate of inclined surface cracks in aluminum and titanium alloys
Fracture and Structural Integrity, 2022 In this paper the fatigue crack growth tests were carried out on surface-crack tension (SCT) specimens, made of 7050 and Ti6Al4V alloys, with initial semi-elliptical surface cracks.

Thermoelastic investigations for fatigue life assessment
, 2004 An investigation is presented on the suitability and accuracy of a thermoelastic technique for the analysis of fatigue cracks. The stress intensity factor ranges ΔKI and ΔKII are determined from thermoelastic data recorded from around the tip of a sharp ...

Interface damage model for fatigue-driven fracture
MATEC Web of Conferences, 2018 A fatigue interface damage model is presented that is based on combining a fatigue evolution law with a static interface damage model. The fatigue model elegantly enables the simulation of crack initiation and propagation in a computationally efficient ...
