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

Size-affected dislocation-mediated plasticity is important in a wide range of materials and
technologies. Here we develop a generalized size-dependent dislocation-based model that …

Predicting the strain hardening properties of crystals constitutes a long-standing challenge
for dislocation theory. The main difficulty resides in the integration of dislocation processes …

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 …

When metals plastically deform, the density of line defects called dislocations increases and
the microstructure is continuously refined, leading to the strain hardening behavior. Using …

Prediction of the plastic deformation behavior of single crystals based on the collective
dynamics of dislocations has been a challenge for computational materials science for a …

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

Three-dimensional (3-D) dislocation dynamics simulations were employed to examine the
fundamental mechanisms of plasticity in small-scale face-centered cubic single crystals …

Crystal plasticity is mediated through dislocations, which form knotted configurations in a
complex energy landscape. Once they disentangle and move, they may also be impeded by …

Dislocations play a vital role in the mechanical behavior of crystalline materials during
deformation. To capture dislocation phenomena across all relevant scales, a multiscale …
