Abstract

A semi-continuum model is constructed for the analysis of fee crystal nanofilms to study the size dependence of the elastic properties. Unlike the classical continuum theory, the current model directly takes the discrete nature in the thickness direction into consideration. In-plane Young's modulus, and in-plane and out-plane Poisson's ratios are investigated with this model and it is found that the values of the elastic moduli (Young's modulus and Poisson's ratios) depend on the film thickness and approach the bulk value asymptotically.
