Assessment of microstructure- and inclusion-induced fatigue crack initiation in bainitic/martensitic rail steels: competing and synergistic effects
TL;DR: In this paper , the authors emphasized the competing and synergistic effects of microstructure and non-metallic inclusion on subsurface fatigue crack initiation behaviors of bainitic/martensitic rail steels through multi-scale characterizations on the microstructures and inclusion features in the crack initiation area.

Yating Zhang,Kun Zhang,Zheng Hu,Tianyu Chen,Wanhao Zhang,Kongjie Jin,Cheng Sun,Luca Susmel,Bingchen Wei +8 more
TL;DR: In this paper , a modified Highly Stressed Volume (HSV) method was proposed to predict fatigue life from a smooth specimen to a notched specimen, which is based on just one empirical evaluation of the HSV.

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.

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.
