Abstract

In recent years, inorganic nanostructures, such as fullerene-like MoS 2 and WS2 nanoparticles, have been shown to be promising candidates for friction and wear reduction in tribological applications. However, it has been demonstrated experimentally that the mechanical response of any given inorganic nanostructure varies depending on its individual structural characteristics such as size, shape, and crystallinity. Here, classical molecular dynamics simulations are performed that investigate the mechanical responses of different types of MoS2 nanostructures during uniaxial compression. The results illustrate the dependence of mechanical behavior on nanoparticle structure and, in particular, indicate that the mechanical properties of MoS2 nanostructures vary significantly with changes in the orientation of the MoS2 walls at the interface.
