Decades of advancements in strategies for the calculation of atomic interactions have
culminated in a class of methods known as machine-learning interatomic potentials …

Coarse-grained materials are widely accepted to display the highest strain hardening and
the best tensile ductility. We experimentally report an attractive strain hardening rate …

Multi–principal element alloys (MPEAs) containing three or more components in high
concentrations render a tunable chemical short-range order (SRO). Leveraging large-scale …

Due to their excellent mechanical properties including high modulus, high strength, large
ductility and low density, nanocarbon like the graphene (Gr) and carbon nanotubes (CNTs) …

The severe difficulty to resolve simultaneously both the macroscopic deformation process
and the dislocation dynamics on the atomic scale limits our understanding of crystal …

We present molecular dynamics simulations of shock compression and spall fracture in [111]
copper single crystals with pre-existing dislocations. Shock waves are simulated for an …

Accurate crystal plasticity models that faithfully capture the behavior of single crystals under
a wide range of loading conditions, such as loading direction, strain rate, and temperature …

By combining experiments and modeling from three US national laboratories, we explore
compressive strength in a well-characterized material, tantalum, across pressures from zero …

Numerous studies have investigated the strain rate sensitive behaviors of materials,
consistently reporting enhanced stress values and increased dislocation density with rising …

Although tension-compression (TC) asymmetry in yield strength was rarely documented in
coarse-grained face centered cubic (FCC) metals as critical resolved shear stress (CRSS) …
