  • ABSTRACT: The mechanism of the tensile deformation of face centered cubic platinum nanowires was investigated by molecular dynamics simulation in which the interactions are expressed by the embedded atom method potential. The two different thicknesses (1.9 nm and 9.8 nm) of nanowires were used to understand the role of surface effects on the mechanical properties of platinum nanowires. The yield stress and strain values were determined by the elastic recovery test which was performed for both nanowires. For 9.8 nm platinum nanowire, the average stress has been governed by core atoms while the surface atoms are more effective to define the mechanical properties of the 1.9 nm platinum nanowire
