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 …

There has been a challenge for many decades to understand how heterogeneities influence
the behavior of materials under shock loading, eventually leading to spall formation and …

The multi-scale damage behaviors and underlying mechanisms of hierarchically structured
high-strength martensitic steels are investigated via plate-impact recovery experiments …

Under shock loading, the spall strength of nanocrystals exhibits intricate grain-size effects
due to the presence of abundant grain boundary and dislocation activities. However, the …

It is generally recognized that single crystals exhibit orientation-dependent elastic and
plastic responses. However, it is less known how the dynamic tensile, or spall, strength …

It is a new beginning for innovative fundamental and applied science in nanocrystalline
materials. Many of the processing and consolidation challenges that have haunted …

We investigate the effect of grain boundary inclination with respect to the loading direction
on void nucleation at a boundary, using plate impact experiments on polycrystalline copper …

To comprehend the mechanical behavior of a polycrystalline material, an in-depth analysis
of individual grain boundary (GB) and dislocation interactions is of prime importance. In the …

Most structural materials are polycrystalline aggregates whose constituent crystals are
irregular in shape, have anisotropic mechanical properties and contain a variety of defects …

We performed a series of systematic spall experiments on single-crystal copper in an effort
to determine and isolate the effects of crystal orientation, peak stress, and unloading strain …
