Deformation twinning is an important plastic carrier competing with the ordinary dislocation
slip in a broad class of crystalline solids, which critically controls the mechanical properties …

Machine learning has proven to be a powerful technique during the past decades. Artificial
neural network (ANN), as one of the most popular machine learning algorithms, has been …

The concepts of twinning shears and twinning modes are introduced. The early attempts to
predict these features are presented. This is followed by a detailed discussion of the formal …

Recent experiments on nanostructured materials, such as nanoparticles, nanowires,
nanotubes, nanopillars, thin films, and nanocrystals have revealed a host of “ultra-strength” …

Most metallic elements have a crystal structure that is either body-centered cubic (bcc), face-
centered close packed, or hexagonal close packed. If the bcc lattice is the …

Dislocation nucleation from a stressed crack tip is analyzed based on the Peierls concept. A
periodic relation between shear stress and atomic shear displacement is assumed to hold …

The strength of metal crystals is reduced below the theoretical value by the presence of
dislocations or by flaws that allow easy nucleation of dislocations. A straightforward method …

We report on large-scale nonequilibrium molecular dynamics simulations of shock wave
compression in tantalum single crystals. Two new embedded atom method interatomic …

The ideal shear strength is the minimum stress needed to plastically deform an infinite
dislocation-free crystal and is an upper bound to the strength of a real crystal. We calculate …

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