Determination of mechanical properties of FCC nano-beams based on molecular dynamics simulations

Abstract

In this research, we have modeled nano-Beams using molecular dynamics. The scope of our study is FCC metals, therefore an appropriate inter-atomic potential for this kind of materials must be chosen. A multi-body long-range potential proposed by Sutton-Chen, which has been used in many physical investigations of FCC metals is applied in our study. Using conducted simulations, the different mechanical properties of material such as elastic modulus, shear modulus and poisonpsilas ratio are calculated. The results show that the elastic properties decrease with increase in nano cantilever size.
