Fatigue of structures and materials in the 20th century and the state of the art
TL;DR: This article surveys the historical development of scientific and engineering knowledge about fatigue of materials and structures in the 20th century, including fatigue as a material phenomenon, prediction models for fatigue properties of structures, and load spectra.

A study of fatigue crack closure by elastic-plastic finite element analysis for constant-amplitude loading
J. Wu,Fernand Ellyin +1 more
TL;DR: In this article, a comprehensive elastic-plastic constitutive model is employed in a finite element analysis of fatigue crack closure, and an improved node release scheme is used to simulate crack growth during cyclic loading, which eliminates the associated numerical difficulties.

Investigation of fatigue crack closure using multiscale image correlation experiments
Jay Carroll,C. Efstathiou,John Lambros,Huseyin Sehitoglu,B. Hauber,S. M. Spottswood,Ravinder Chona +6 more
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.

Mode I fatigue crack arrest in tensile steel members using prestressed CFRP plates
Ardalan Hosseini,Ardalan Hosseini,Elyas Ghafoori,Masoud Motavalli,Masoud Motavalli,Masoud Motavalli,Alain Nussbaumer,Xiao Ling Zhao +7 more
TL;DR: In this paper, a simple analytical model is proposed to calculate the required prestressing level in the CFRP reinforcements in order to arrest the propagation of an existing fatigue crack in tensile steel members.

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.
