Grain boundaries (GBs) are central defects for describing polycrystalline materials, and
playing major role in a wide-range of physical properties of polycrystals. Control over GB …

Numerical algorithms for discrete dislocation dynamics simulations are investigated for the
purpose of enabling strain hardening simulations of single crystals on massively parallel …

In the past twenty years, new experimental approaches, improved models and progress in

A unified model coupling 3D dislocation dynamics (DD) simulations with the finite element
(FE) method is revisited. The so-called Discrete-Continuous Model (DCM) aims to predict …

In this paper, we propose a novel full-field approach based on the fast Fourier transform
(FFT) technique to compute mechanical fields in periodic discrete dislocation dynamics …

The development of a dislocation-based continuum theory of plasticity remains one of the
central challenges of applied physics and materials science. Developing a continuum theory …

Discrete dislocation dynamics (DDD) is a widely employed computational method to study
plasticity at the mesoscale that connects the motion of dislocation lines to the macroscopic …

Significant progress in our understanding of plasticity in body-centered cubic (bcc) metals
during the last decade has enabled rigorous multiscale modeling based on quantitative …

During plastic flow of crystalline solids, dislocations self-organize in the form of patterns, with
a wavelength that is inversely proportional to stress. After four decades of investigations, the …

A new efficient framework coupling the two dimensional (2D) discrete dislocation dynamics
(DDD) and the extended finite element method (XFEM) is developed for modeling the …
