In this article, the mechanical properties of the boron-nitride nano- sheet (BNNS)-reinforced aluminium (Al) nanocomposite are estimated by using molecular dynamics (MD) models. Different nanoscale representative volume elements (NRVEs) have been considered to predict the stiffness and strength properties of BNNS-Al NRVE under tensile and shear loading conditions. A comparison is also made between the stress-strain behaviour of graphene sheet (GS)-Al and BNNS-Al nanocomposites. BNNS-Al nanocomposites are found to be more ductile and less stiff than GS-Al nanocomposite. Effect of layering of BNNS on the stress-strain response is observed and found that, in contrast to the layering of graphene sheets, the stiffness properties of BNNS-reinforced Al nanocomposite are not sensitive to the layering of BNNS. It is established that the layering of BNNS marginally enhance the mechanical properties of the nanocomposite. It is also found that the chirality of BNNS marginally affects the stress-strain response of the nanocomposite irrespective of the loading condition i.e. tensile/shear loading.
