摘 要:Negative Poisson’s ratio(NPR),also known as“auxetic,is a highly desired property in a wide range of future industry *** employing molecular dynamics(MD)simulation,metal matrix nanocomposites reinforced by graphene sheets are studied in this *** the simulation,single crystal copper with crystal orientation絵110is selected as the matrix and an embeddedatom method(EAM)potential is used to describe the interaction of copper *** aligned graphene sheet is selected as reinforcement,and a hybrid potential,namely,the Erhart-Albe potential,is used for the interaction between a pair of carbon *** interaction between the carbon atom and copper atom is approximated by the Lennard-Jones(L-J)*** simulation results showed that both graphene and copper matrix possess in-plane *** temperature-dependent mechanical properties of graphene/copper nanocomposites with in-plane NPRs are obtained for the first time.
