In this interpretive review, fatigue in metallic systems is considered primarily from the
perspective of interactions between the microstructure, the deformation mode and the …

Viscoplastic behavior of metallic materials is manifested by collective behavior of lattice
defects at multiple length scales. The full gamut of length scales, from atomic to …

Recent trends towards simulation of the cyclic slip behavior of polycrystalline and polyphase
microstructures of advanced engineering alloys subjected to cyclic loading are facilitating …

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 …

Symmetric and asymmetric tilt grain boundaries in Cu and Al were generated using
molecular statics energy minimization in a classical molecular dynamics code with in-plane …

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 …

Light‐weight aluminum (Al) alloys have widespread applications. However, most Al alloys
have inherently low mechanical strength. Nanotwins can induce high strength and ductility …

Using in situ nanoindentation in a high-resolution transmission electron microscope we
have studied the interaction of glide dislocations with a Σ3 {111} coherent twin boundary …

Atomistic simulations are used to investigate how the stress required for homogeneous
nucleation of partial dislocations in single crystal copper under uniaxial loading changes as …

Grain boundaries are the interfaces between differently oriented crystals of the same
material. The underlying structures of grain boundary play a significant role in mechanical …
