Expansions for the linear-elastic contribution to the self-interaction force of dislocation curves
TL;DR: In this paper, the self-interaction force of dislocation curves in metals has been investigated in terms of the nonlocal interaction between dislocation curve segments, which can be described by linear elasticity when the segments are further apart than the atomic scale of size.

Partial Dislocation Interactions in a Face-Centred Cubic Model Sodium Lattice
TL;DR: In this paper, the authors deal with the mutual interaction and individual core structures of Shockley partial dislocations in a fcc model sodium lattice, and show that the nonlinearity at small separations is of an unexpected sense, such that the partial separation is greater than the linear elastic value.

Constitutive models
TL;DR: The VPSC model is fully anisotropic and applicable to aggregates with arbitrary crystal symmetry, including multiphase aggregates as discussed by the authors , and it predicts the evolution of stress, strain, and crystal orientation of individual grains, and the hardening and texture evolution of aggregates subjected to combined and evolving stress and strain rate conditions.

J-Integral Evaluation of Continuous Dislocation Emissions from the Crack Tip near Grain Boundaries in Atomic Simulations
TL;DR: In this article, the authors evaluate the mechanical field around the crack tip using J-integral in atomic simulations, and find that quantitative evaluations of the crack-tip shielding effect due to EGBDs can be performed by taking grain boundary structures into account.

Interaction between an Edge Dislocation and Lamellar Inclusion with Finite Length on Interface
TL;DR: In this paper, a finite element model of an edge dislocation with a lamellar inclusion is analyzed by considering initial strain, and the force exerted on the dislocation due to the elastic interaction can be numerically obtained by calculating the reduction of the potential energy, firstly proposed by Peach-Koehler.
