Nanoscale features present in structural and functional materials affect their macroscopic
properties and hence have been extensively studied. As experimental investigations of …

The use of high-power pulsed lasers to probe the response of materials at pressures of
hundreds of GPa up to several TPa, time durations of nanoseconds, and strain rates of 10 6 …

An ultra-strong and ductile Mg-8.2 Gd-3.8 Y-1Zn-0.4 Zr (wt pct) alloy was developed by
using hot extrusion to modify the microstructure via forced-air cooling and an artificial aging …

We examine the effect of grain size on the dynamic failure of tantalum during laser-shock
compression and release and identify a significant effect of grain size on spall strength …

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 …

Abstract We present Non-Equilibrium Molecular Dynamics (NEMD) simulations of shock
wave compression along the [001] direction in monocrystalline Tantalum, including pre …

Strain rate, temperature, and microstructure play a significant role in the mechanical
response of materials. Using non-equilibrium molecular dynamics simulations, we …

The ability of amorphous intergranular films to mitigate damage formation at grain
boundaries is studied with molecular dynamics simulations. We find that such films can alter …

The graphene (Gr) can effectively confine the dislocation propagation, allowing for the
pronounced strengthening effect. However, due to the technical limitations of atomic …

Nanoindentation simulations are a helpful complement to experiments. There is a dearth of
nanoindentation simulations for bcc metals, partly due to the lack of computationally efficient …
