Abstract Molecular dynamics method incorporating with parallel computing technique was employed to study the mechanical properties of textured polycrystalline nanofilms with fixed out-of-plane normal direction. The grain size and film
thickness effects on both the elastic and plastic properties of the copper nanofilm were examined. It is shown from the simulation that the elastic and plastic properties (i.e., Young’s modulus, Poisson’s ratio, biaxial yield stress, etc) of textured polycrystalline nanofilms depend on the grain size and the film thickness. As the grain size of the nanofilm become larger, the Young’s modulus and biaxial yield stress increase but the Poisson’s ratio decreases.… More >
