Dislocation cores, the regions in the immediate vicinity of dislocation lines, control a number
of properties such as dislocation mobility, cross-slip and short-range interactions with other …

We present a self-contained review of the discrete dislocation dynamics (DDD) method for
the numerical investigation of plasticity in crystals, focusing on recent development and …

Traditionally, precipitates in a material are thought to serve as obstacles to dislocation glide
and cause hardening of the material. This conventional wisdom, however, fails to explain …

The mechanisms of plasticity in metal nanowires with diameters below 100 nm are
reviewed. At these length scales, plasticity in face-centered-cubic metals subjected to …

We develop the theory of homogeneous nucleation of dislocations, which predicts plasticity
incipience in FCC single crystal using material properties at elastic stage. In contrast to …

Molecular dynamics (MD) simulations are employed to study the interaction mechanisms
between dislocations and nano-precipitates in CuFe alloys. On one hand, the critical shear …

Dislocation nucleation plays a critical role in the plastic deformation of crystalline materials.
However, it is challenging to predict the active mode and associated rate of dislocation …

In this study, a chemical order related concept “history-dependent multi-layer generalized
stacking fault energy”(HDML-GSFE) was proposed, and it was then demonstrated by …

Incipient plasticity of crystals is usually initiated from versatile pre-existing crystalline defects
of different geometries and length scales that formed during materials fabrication and …

Hemispherical nanoparticles of Ag-33 at.% Au and Ag-60 at.% Au alloys were fabricated by
solid state dewetting of Ag-Au bilayers deposited on a sapphire substrate. The in-situ …
