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:

Modelling of overload effects on fatigue crack initiation in case of carbon steel
TL;DR: In this article, the authors deal with the modelling of short crack initiation within a microstructure of medium carbon steel under fatigue loading, as well as with the influence of overload on the crack initiation period.
Journal ArticleDOI
Mechanisms and modeling of low cycle fatigue crack propagation in a pressure vessel steel Q345
TL;DR: Based on the theory of elastic-plastic fracture mechanics, an analytical model is presented in this article to determine the CTOD for cracked component subjected to cyclic axial inplane loading.
Journal ArticleDOI
On the accuracy of spectral solvers for micromechanics based fatigue modeling
TL;DR: A framework based on FFT allows predicting fatigue life with a similar accuracy than using FEM but strongly reducing the computational cost.

Influence of cryorolling and followed by annealing on high cycle fatigue behavior of ultrafine grained Al 2014 alloy
TL;DR: In this paper, the effects of cryorolling and followed by annealing on the high cycle fatigue strength of bulk ultrafine grained (UFG) Al 2014 alloy were investigated.

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.
