TLDR
In this paper, the authors focus on experimental observations of strain localization and the theory and numerical analysis of both slip irreversibilities and low energy configuration defect structures, which are the early signs of damage during cyclic loading.About:

Fatigue Characterization and Fractographic Analysis of Aluminium 6063 Alloy
TL;DR: In this paper , the analysis of fatigue behavior of Al 6063 alloy at the various total strain amplitude (TSA) of 0.4% and 0.8%, which performed through the low cycle fatigue testing machine at the frequency rate of 0 2 Hz.
Assessing variability in microstructural influence on fatigue crack growth behavior
TL;DR: It is suggested that within the next few weeks, as well as within the coming weeks, this chapter should be rewritten to reflect the changing climate in the United States and Canada.

Effects of Diffusible Hydrogen on Fatigue Life of Spot Welds in High-tensile-strength Steel Sheets
TL;DR: In this article , the effects of diffusible hydrogen on spot welds were investigated via tensile-shear fatigue tests under cathodic hydrogen charging, and the correlation between static testing and dynamic fatigue testing was investigated.
Journal ArticleDOI
Microstructure and Fatigue Performance of Ti6Al4V Produced by Laser Powder Bed Fusion after Post-Heat Treatment
TL;DR: In this article , a laser remelting method was used to reduce porosity defects inside the Ti-6Al-4V alloy, and three annealing treatments (AT) and three solution-aging treatments (SAT) were used to study the effect of the two-phase zone (α + β) microstructure on fatigue life and fatigue crack growth behavior.

Fatigue Life Testing of the Round Link Mining Chains
Ryszard Kandzia,Mariusz Szot +1 more
TL;DR: In this paper , the wear of link chains is concentrated in three areas, depending on the installation location and function of the individual links, namely: in the joints (the points of contact between two links), on the outer surfaces of the arches and on the straight sections of the links.

The Phenomena of Rupture and Flow in Solids
TL;DR: In this article, the authors investigated the effect of surface scratches on the mechanical strength of solids, and some general conclusions were reached which appear to have a direct bearing on the problem of rupture, from an engineering standpoint, and also on the larger question of the nature of intermolecular cohesion.

Metal fatigue in engineering
R. I. Stephens,H. O. Fuchs +1 more
TL;DR: In this paper, the authors present methods proven successful in practice, such as safe-life, fail-safe, forecasting of service reliability, monitoring, and inspection; macroscopic and microscopic aspects of fatigue behavior; principles for determining fatigue crack growth and final fracture; scatter of data and statistical methods; environmental factors; and fatigue of joints and compounds.
Journal ArticleDOI
The structure of high-angle grain boundaries
TL;DR: In this paper, a superimposed dislocation network is proposed for the cubic system, which is a natural extension of previous dislocation models and models based on coincidence relationships, and explains many of the observed properties of grain boundaries.

Ductile versus brittle behaviour of crystals
James R. Rice,Robb Thomson +1 more
TL;DR: In this article, a necessary criterion for brittle fracture in crystals is established, in terms of the spontaneous emission of dislocations from an atomically sharp cleavage crack, and the stability of a sharp crack against emission of a blunting dislocation for a number of crystals and crystal types in two dimensions and the energy to form a stable loop of dislocation from the crack tip in three dimensions.

Dislocation wall and cell structures and long-range internal stresses in deformed metal crystals
TL;DR: In this article, a simple model for single-slip and multiple-slink deformation is proposed, in which the crystal is considered as a composite consisting of hard dislocation walls of high local dislocation density which are separated by soft regions of low local dislocations density.
