Atomistic simulations of the mechanical behavior of graphene
Abstract
Graphene is an extremely important topic of research because of its extraordinary physical and electrical properties. In this study, molecular dynamics simulation was used to predict various mechanical properties of graphene such as its Young's modulus, Shear modulus, Poisson's ratio etc. The research done to determine the shear modulus, gave us clues to the origin of experimentally observed ridge defects on the graphene surface. Finally we performed a detailed study of the frictional behavior of multi-layered graphene. We propose a model which explains experimental observations and identities dominant phenomena resulting in the low frictional properties of solid lubricants.
