Abstract
Graphene (Gr) has extraordinary properties such as excellent mechanical,
electrical, and thermal strength. Adding Gr into the metal matrix enhances the overall
properties of the nanocomposite (NC). The advantages and disadvantages of any kind
of NC depend on various defects such as vacancy, holes, cracks, etc. and these defects
depend on the type of application. This review article presents an extended finite
element method (X-FEM) to model and analyze the mechanical properties of graphene
nanocomposites (GNC). X-FEM is an excellent tool to analyze crack growth in
graphene sheets (GS) and GNC. This FEM analysis is performed using different
properties such as Young’s modulus, Poisson’s ratio, and mass density. It has been
observed from the review that aligning and distributing GS randomly enhances the
mechanical properties but if crack formation occurs in the NC or on the GS then
properties start degrading.
Keywords: Crack growth, Graphene, Poisson’s ratio, Simulation.
