A predictive fatigue life model for anodized 7050 aluminium alloy [PDF]
, 2013 The objective of this study is to predict fatigue life of anodized 7050 aluminum alloy specimens. In the case of anodized 7050-T7451 alloy, fractographic observations of fatigue tested specimens showed that pickling pits were the predominant sites for ...

Modelling probabilistic fatigue crack propagation rates for a mild structural steel [PDF]
Fracture and Structural Integrity, 2015 A class of fatigue crack growth models based on elastic–plastic stress–strain histories at the crack tip region and local strain-life damage models have been proposed in literature.

Influence of woven ply degradation on fatigue crack growth in thin notched composites under tensile loading [PDF]
, 2010 This paper deals with the fatigue of the through the-thickness crack propagation in thin notched composite laminates made of two glass woven plies. It highlights the different crack growths between warp and weft directions of the woven ply.

Crack growth behaviour of aluminium wrought alloys in the Very High Cycle Fatigue regime [PDF]
MATEC Web of Conferences, 2018 Investigations have shown that in the regime of Very High Cycle Fatigue (VHCF) “natural” crack initiation often takes place underneath the material surface leading to crack propagation without contact to atmospheric components.

Size effects on residual stress and fatigue crack growth in friction stir welded 2195-T8 aluminium - Part I: Experiments [PDF]
, 2011 Residual stress fields were measured in three different sizes of Compact-Tension (C(T)) and eccentrically loaded single edge notch (ESE(T)) specimens containing transverse or longitudinal welds. The effect of size on residual stress profiles was studied.

Influence of corrosion and creep on intergranular fatigue crack path in 2XXX aluminium alloys [PDF]
, 2010 In this paper, two examples of the influence of time-dependent processes on crack path in two 2XXX aluminium alloys are presented. The first example is concerned with corrosion–fatigue crack growth resistance of a 2024 T351 alloy cracked in the S–L ...

Fatigue crack growth behaviour and life prediction for 2324-T39 and 7050-T7451 aluminium alloys under truncated load spectra [PDF]
, 2010 This paper presents a study of crack growth behaviour in aluminium alloys 2324- T39 and 7050-T7451 subjected to flight-by-flight load spectra at different low- stress truncation levels. Crack branching was observed in the higher truncation levels for the
