Nanocrystalline (nc) materials can be defined as solids with grain sizes in the range of 1–
100 nm. Contrary to coarse-grained metals, which become more difficult to twin with …

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 …

Structural alloys are often strengthened through the addition of solute atoms. However,
given that solute atoms interact weakly with the elastic fields of screw dislocations, it has …

New perspectives on the phase field approach in modeling deformation and fracture at the
fundamental defect level are reviewed. When applied at sub-angstrom length scales the …

In the past twenty years, new experimental approaches, improved models and progress in
simulation techniques have brought new insights into longstanding issues concerning …

We present findings on the structure, energies and behaviour of defects in irradiated
graphitic carbon materials. Defect production due to high-energy nuclear radiations …

In an effort to establish a scientific foundation for the computational development of
advanced Mg-based alloys, a systematic study of the generalized stacking fault (GSF) …

Controlling the balance between strength and damage tolerance in high-entropy alloys
(HEAs) is central to their application as structural materials. Materials discovery efforts for …

" This book provides both the theoretical foundation, as well as the authors' latest
contributions to micromechanics and its applications in nanomechanics, nanocomposites …

We have employed the semidiscrete variational generalized Peierls-Nabarro model to study
the dislocation properties of aluminum. The generalized-stacking-fault (GSF) energy surface …
