Shear-banding is a ubiquitous plastic-deformation mode in materials. In metallic glasses,
shear bands are particularly important as they play the decisive role in controlling plasticity …

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 …

Refractory high-entropy alloys (RHEAs) are designed for high elevated-temperature
strength, with both edge and screw dislocations playing an important role for plastic …

Covalently bonded ceramics exhibit preeminent properties—including hardness, strength,
chemical inertness, and resistance against heat and corrosion—yet their wider application is …

Dislocation motion in body centered cubic (bcc) metals displays a number of specific
features that result in a strong temperature dependence of the flow stress, and in shear …

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

This book presents a broad collection of models and computational methods-from atomistic
to continuum-applied to crystal dislocations. Its purpose is to help students and researchers …

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 …

We develop a non-singular, self-consistent framework for computing the stress field and the
total elastic energy of a general dislocation microstructure. The expressions are self …

In situ nanomechanical tests are carried out to investigate the tensile and compressive
behavior of〈 001〉-oriented body-centered cubic (bcc) metals W, Mo, Ta and Nb with …
