Superhard materials have many technological applications.[1,2] Recently it has been reported that osmium diboride has a large bulk modulus combined with high hardness,and consequently is a most intere
We developed a hybrid approach to quantitatively characterize phonon quasiparticles by combing first-principles molecular dynamics and lattice dynamics [1].
The dynamic fragmentation of shock-melted metal is a topic of increasing interest in shock physics.However,high-quality experimental studies of the phenomenon are limited,experimental data that are es
With molecular dynamics simulations,we investigate the effects of porosity and specific surface area on shock response of open-cell nanoporous Cu foams,including compression,shock velocity-particle ve
