Finite element analysis of plasticity-induced fatigue crack closure: an overview
TL;DR: The state-of-the-art in finite element analysis for plasticity-induced fatigue crack closure can be found in this article, where a comprehensive overview is presented, summarizing issues which must be considered and emphasizing potential difficulties.
Journal ArticleDOI
Evaluation of overload effects on fatigue crack growth and closure
TL;DR: In this article, Fatigue crack propagation tests with single tensile peak overloads have been performed in 6082-T6 aluminium alloy at several baseline Δ K levels and stress ratios of 0.05 and 0.25.

TL;DR: In this paper, two full-field macro-scale methods are introduced for estimating fatigue crack opening levels based on digital image correlation (DIC) displacement measurements near the crack tip, and the results of these experiments point to a normalized crack tip opening level of 0.35 for R Â∼ 0 loading in grade 2 titanium.
Journal ArticleDOI
Influence of grain structure and slip planarity on fatigue crack growth in low alloying artificially aged 2xxx aluminium alloys
TL;DR: In this paper, the relationship between the crack path and the microstructure, i.e. grain structure and slip planarity, is assessed semi-quantitatively and a criterion to evaluate the propensity for slip band formation is derived and reasonable correlation is found between the fatigue fracture behaviour of the three alloys and this criterion.
