Atomistic-based multiscale and molecular dynamics modeling are powerful tools to simulate
the localized strain problems, offering tremendous opportunities to bridge the knowledge …

Abstract The Frank-Read (FR) source is a well-known intragranular dislocation source that
plays an important role in size-dependent dislocation multiplication in metallic crystals. In …

Many elementary deformation processes in metals involve the motion of dislocations. The
planes of glide and specific processes dislocations prefer depend heavily on their atomic …

Dislocations and heat conduction are essential components that influence properties and
performance of crystalline materials, yet the modelling of which remains challenging partly …

Mixed-type dislocations are prevalent in metals and play an important role in their plastic
deformation. Key characteristics of mixed-type dislocations cannot simply be extrapolated …

In the continuum context, the displacements of atoms induced by a dislocation can be
approximated by a continuum disregistry field. In this work, two phase-field (PF)-based …

The strengthening of metals by nano-scale obstacles is mainly attributed to the impediment
to glide dislocations offered by these obstacles. It is important to understand the …

In this work, selecting the equal-molar CoNiRu multi-principal element alloy (MPEA) as a
model material, we study dislocation core structures starting from first principles. We begin …

Accurately representing the process of porosity-based ductile damage in polycrystalline
metallic materials via computational simulations remains a significant challenge. The …

Strengthening in complex multicomponent systems such as solid solution alloys is controlled
primarily by the dynamic interactions between dislocation lines and heterogeneously …
