A new dislocation-mechanics based crystallographic theory has been developed to model
the mechanical behaviour of single-phase FCC polycrystal aggregates. In the theory …

A three-dimensional, large deformation crystal plasticity model is presented in which the
lengthscale effect is incorporated through the explicit coupling of the density of geometrically …

Following the approach by Ashby, one can consider that strain compatibility between
adjacent grains of a polycrystal generates geometrical dislocations. These dislocations …

In this contribution, a computational approach to modeling size-dependent self-and latent
hardening in polycrystals is presented. Latent hardening is the hardening of inactive slip …

Thin copper single crystals with a common axial orientation but with two different surface
orientations are deformed in tension. The surface orientations were chosen so that in the …

Cross-slip of screw dislocations is a dislocation process involved in dislocation structuring,
work hardening, and fatigue. Cross-slip nucleation in FCC solid solution alloys has recently …

The relationships between the dislocation density, flow stress and stored energy in
polycrystalline copper have been determined experimentally. The stored energy can be …

A computational framework for the discrete dislocation dynamics simulation of body-
centered cubic (bcc) metals which incorporates atomistic simulation results is developed …

A new three-scale model of polycrystal accounting for grain refinement is proposed. The
model is embedded into the crystal plasticity framework. With the experimental reference to …

A multiscale modeling methodology involving discrete dislocation dynamics (DDD) and
crystal plasticity finite element method (CPFEM) was used to study the grain size effect in …
