ABSTRACT

This chapter discusses the finite model analysis is used to model graphene sheet using truss elements. Right from their discovery in 1991 by Iijima, carbon nanotubes (CNTs) have spurred considerable interest among scientists and engineers because of their atypical physical properties. The use of CNTs as reinforcing materials in nano-composites has made it necessary to predict their mechanical properties and assess their deformation under loading. Mazahery and Shabani conducted a finite element (FE) investigation on the effects of the increase in the contents of nano-silicon carbides in an aluminum alloy on its hardness, porosity, elongation, yield strength, and ultimate tensile strength. A CNT is a cylinder of graphitic carbon atoms bonded on the surface in a hexagonal array consistent with a space-frame structure. Continuum representation of the molecules is used in the FE modeling to simulate the molecular behavior of the carbon atoms in the graphene sheet.
