Hardening or softening associated with the increase of dislocation density is correlated with
strain rate and dislocation density. Taking aluminum as a model material, we investigate the …

Dislocations are the most important material defects in crystal plasticity, and although
dislocation mechanics has long been understood as the underlying physical basis for …

Dislocation glide is a general deformation mode, governing the strength of metals. Via
discrete dislocation dynamics and molecular dynamics simulations, we investigate the strain …

Mechanical response of metals is strongly dependent on the strain rate and exhibits drastic
change as the strain rate varies across> 10 orders of magnitude from quasistatic to shock …

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 …

This paper presents a crystal plasticity based finite element analysis employing the new
microstructure-based strain hardening model recently presented by Saimoto and Van Houtte …

We present a crystal plasticity model that incorporates cross-slip of screw dislocations
explicitly based on dislocation densities. The residence plane of screw dislocations is …

The mechanical anisotropic properties of aluminum alloy are studied using multi-level
approaches for strain-rate and temperature-sensitive large plastic deformation of …

To improve metal formability, high temperature forming has become a desired
manufacturing process. Phenomenological plasticity models are widely used in this …

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