A unified physically based crystal plasticity model for FCC crystalline materials is developed.
This statistical dislocation dynamics based model considers the cellular dislocation …

A crystal plasticity model for body-centered-cubic (BCC) single crystals, taking into account
the plastic anisotropy due to non-planar spreading of screw dislocation cores is presented …

Crystal plasticity models enable predictions of macroscopic deformation behavior as well as
texture evolution of metallic materials based on mesoscopic deformation at the grain level …

The goal of this work is to formulate a constitutive model for the deformation of metallic
single crystals over a wide range of strain rates, which is integral to computing reliable stress …

In this article, we present a time-dependent deformation mechanism for fcc metal single
crystals in which the resulting deformation is produced by the cumulative effect of dislocation …

This work presents an open source, dislocation density based crystal plasticity modeling
framework, ρ-CP. A Kocks-type thermally activated flow is used for accounting for the …

A new phenomenological strain hardening function is proposed to describe the strain
hardening behavior of metallic materials. The function is based on a simplification of an …

The glide and climb of dislocations are two important plastic deformation mechanisms of the
metallic crystals at elevated temperatures. In this work, a new dislocation density-based …

Based on recent dislocation dynamics simulations investigations, a set of constitutive
equations and model parameters for the description of plasticity of body-centered cubic …

Metal forming processes typically involve changes of strain paths, which are accompanied
by transients in softening or hardening behaviour. The physical cause of these transients in …
