Dislocation–obstacle interactions that resist the glide of dislocations in metals, and hence
increase the applied stress necessary for plastic deformation, are treated at the atomic scale …

Recent advances in analytical and computational modelling frameworks to describe the
mechanics of materials on scales ranging from the atomistic, through the microstructure or …

In atomistic simulations, pseudo-dynamical relaxation schemes often exhibit better
performance and accuracy in finding local minima than line-search-based descent …

A model for simulating the dynamic behaviour of edge dislocations in metals at the atomic
level is presented. The model extends an earlier approach based on an array of edge …

The purpose of this chapter is to discuss the atomic structure and interactions in the
dislocation core and their effects on dislocation mobility from the standpoint of theoretical …

Molecular dynamics simulations of screw dislocations interacting with interstitial Frank loops
are performed using specific boundary conditions in a model face-centered-cubic nickel …

In this paper, the interaction between an edge dislocation and irradiation< 100> sessile self-
interstitial atom (SIA) type dislocation loops (DLs) is studied by atomistic simulations in BCC …

Atomistic simulations reveal a new and unique strengthening mechanism in nanotwinned
metals governed by the collective motion of multiple necklace-like extended jogged …

Dislocation-precipitate interaction and solute segregation play important roles in controlling
the mechanical behavior of Ni-based superalloys at high temperature. In particular, the …

Single-phase concentrated solid solution alloys (CSAs), including high entropy alloys,
exhibit excellent mechanical properties compared to conventional dilute alloys. However …
