Creep of single-crystal superalloys is governed by dislocation glide, climb, reactions and
annihilation. Discrete three-dimensional (3D) dislocation dynamics (DDD) simulations are …

Equations for dislocation evolution bridge the gap between dislocation properties and
continuum descriptions of plastic behavior of crystalline materials. Computer simulations can …

This paper presents a fully coupled glide-climb crystal plasticity model, whereby climb is
controlled by the diffusion of vacancies. An extended strain gradient crystal plasticity model …

A small strain two-dimensional discrete dislocation plasticity framework coupled to vacancy
diffusion is developed wherein the motion of edge dislocations is by a combination of glide …

Abstract A three-dimensional (3D) discrete dislocation dynamics (DDD) creep model is
developed to investigate creep behavior under uniaxial tensile stress along the …

The mechanical behavior of a polycrystalline aluminum in tension was modeled using a
climb-assisted discrete dislocation dynamics (DDD) technique. Special focus was on how …

The mobility of atoms in dislocation core regions is many orders of magnitude faster than in
the surrounding lattice. This rapid atomic transport along dislocation cores plays a significant …

To investigate the mechanical behavior of the microlayered metallic thin films (MMMFs) at
elevated temperature, an enhanced discrete-continuous model (DCM), which couples rather …

Helical dislocations are widely observed in metallic, ionic and covalent crystals and have
significant impacts on the material properties. In this paper, a coupled glide-climb model is …

We develop a framework to investigate thermal creep and annealing in finite domains,
where the climb motion of discrete dislocations is coupled to the diffusion of a continuum …
