Molecular dynamic simulations of an atomic vacancy in FCC metal

Research output: Chapter in Book/Report/Conference proceedingConference contributionpeer-review

Abstract

Atomic lattice strain is an essential part of any vacancy generation, annihilation and atomic mass transport computation. In the literature, there is no consensus on what this value is or how it should be obtained. In this paper, atomic lattice strain due to a vacancy in an FCC metal lattice is obtained by two different methods and compared with other commonly used values reported in the literature. It is shown that using a continuum mechanics approach in conjunction with molecular dynamic simulations yields results similar to the ones obtained by purely based on molecular dynamics considerations.
