In this study, effects of aspect ratio and perforation on the buckling response of
graphene nanosheet (GNS)-embedded aluminum (Al) nanocomposite plate are studied using
molecular dynamics (MD) simulations. The periodic system of GS-Al nanocomposite plate is
built and simulated using molecular dynamics (MD) based software LAMMPS (Large-scale
Atomic/Molecular Massively Parallel Simulator). Embedded atom method (EAM) and
Adaptive Intermolecular Reactive Empirical Bond Order (AIREBO) potentials are employed
to model the interactions between the atoms of Al and carbon atoms, respectively. It is
observed that the buckling strength of square GNS-Al nanocomposite plate deteriorates
drastically due to perforation and the same is also true for plates of higher aspect ratio.
