Abstract

A closed-form model is proposed to evaluate the elastic constants of fee crystal nanofilms as a function of film thickness. Unlike the classical continuum theory, the current model directly takes the discrete nature in the thickness direction into consideration. This semi-continuum model was then applied to derive the Young's modulus and Poisson's ratios of nanofilms. It is found that the values of these elastic constants depend on the film thickness and approach the respective bulk values asymptotically.
