Incorporating grain-level residual stresses and validating a crystal plasticity model of a two-phase Ti-6Al-4 V alloy produced via additive manufacturing
TL;DR: In this article, the effect of grain-level residual stresses via geometrically necessary dislocations is developed and implemented within the crystal plasticity finite element (CPFE) simulation and high-resolution digital image correlation (HR-DIC) on samples subject to cyclic loading.

Mobility of low-angle grain boundaries in pure metals
Myrjam Winning,Anthony D. Rollett,G. Gottstein,David J. Srolovitz,Adele Tzu-Lin Lim,Lasar S. Shvindlerman +5 more
TL;DR: In this article, the mobility of low-angle grain boundaries in pure metals is reviewed and several theoretical treatments are provided; the approach that provides the best agreement with the available experimental data is one in which the mobility is controlled by vacancy diffusion through the bulk to (and from) the dislocations that comprise the boundary that are bowing out between pinning points.

First-order dislocation-magnetic fluxoid interactions
TL;DR: In this paper, the Peach-Koehler formula was used to determine the depinning force of a fluxoid in the mixed state of a type II superconductor by a dislocation.

Constitutive Equations, Rheological Behavior, and Viscosity of Rocks
TL;DR: In this paper, a review of micromechanical mechanisms of deformation and the associated constitutive equations are applied to describing the rheological behavior of rocks and compares predictions based on laboratory-derived flow laws with the viscosity structure of Earth's upper mantle determined from geophysical observations.

Self-organized propagation of dislocations in GaN films during epitaxial lateral overgrowth
TL;DR: In this paper, a self-organized propagation of preexisting dislocations in ELO films is evaluated, where dislocation bundling gives rise to crystallographic tilting in the overgrown region on the mask and leads to a total reduction of threading dislocation density in the film.
