Discrete dislocation dynamics simulations are carried out to systematically investigate the
rate dependent deformation behaviour of polycrystalline bulk copper by varying the loading …

A long standing challenge in computational materials science is to establish a quantitative
connection between the macroscopic properties of plastic deformation with the microscopic …

A combined finite element (FE) simulation and discrete dislocation dynamics (DD) approach
has been developed in this paper to investigate the dynamic deformation of single-crystal …

3D dislocation dynamics (DD) simulations are employed to study the plastic anisotropy of a
single crystal of copper under a wide range of high strain rates, 104–106s-1. The …

We present a dislocation density-based strain hardening model for single crystal copper
through a systematic coarse-graining analysis of more than 200 discrete dislocation …

The yield surface of a material is a criterion at which macroscopic plastic deformation
begins. For crystalline solids, plastic deformation occurs through the motion of dislocations …

This study focuses on modelling the behaviour of single crystal tantalum in Stage 0
characterized by the large activity of edge dislocations and relative inactivity of screw …

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 …

Two-dimensional dislocation dynamics (2D-DD) simulations under fully periodic boundary
conditions are employed to study the relation between microstructure and strength of a …

Modeling of scale-dependent characteristics of mechanical properties of metal polycrystals
is studied using both discrete dislocation dynamics and continuum crystal plasticity. The …
