Deformation behaviour of aluminium nanocrystals under shock-wave loading

Abstract

Nonequilibrium process of shock-wave loading of aluminum nanocrystals were investigated numerically under uniaxial stress conditions using molecular dynamics simulations (MD). Deformation curves, time dependence of strain rate and the change in potential energy were constructed. Calculated properties of aluminium using embedded atom interatomic potential are compared with each other. Relationship between the calculated characteristics are discussed. The behaviour of deformation curves for two different aluminium nanosrystals is explained. The problems of modeling the deformation hardening of aluminum nanocrystals are considered. © 2019 Published under licence by IOP Publishing Ltd.
