Grain size has a profound effect on the mechanical response of metals. Molecular dynamics
continues to expand its range from a handful of atoms to grain sizes up to 50 nm, albeit …

To fully understand the plastic deformation of metallic polycrystalline materials, the physical
mechanisms by which a dislocation interacts with a grain boundary must be identified …

Atomic-level modeling of materials provides fundamental insights into phase stability,
structure and properties of crystalline defects, and to physical mechanisms of many …

The energetics and length scales associated with the interaction between point defects
(vacancies and self-interstitial atoms) and grain boundaries in bcc Fe was explored …

Grain boundaries (GBs) provide a strengthening mechanism in engineering materials by
impeding dislocation motion. In a polycrystalline material, there is a wide distribution of GB …

Research trends in metal plasticity over the past 25years are briefly reviewed. The myriad of
length scales at which phenomena involving microstructure rearrangement during plastic …

This book describes behavior of crystalline solids primarily via methods of modern
continuum mechanics. Emphasis is given to geometrically nonlinear descriptions, ie, finite …

The mechanical response of engineering materials evaluated through continuum fracture
mechanics typically assumes that a crack or void initially exists, but it does not provide …

High-entropy alloys (HEAs) are considered as potential structural materials for aerospace
and defense applications where impacts are recurrently encountered. The dynamic …

To understand the underlying mechanisms that control the mechanical properties of
nanostructured metals, an insight into the role of the grain boundary in dislocation-driven …
