Abstract
A numerical approach based on the Embedded Finite Element Method (E-FEM) has been elaborated in order to model size effect in nanocomposites. For this purpose, the E-FEM standard Statically and Kinematically Optimal Nonsymmetric formulation is enhanced to incorporate a surface elasticity at the interface between the matrix and the inclusions. The results obtained with the proposed approach for a couple of problems have been compared to analytical solutions and other numerical approaches. This study has been carried out considering both linear and nonlinear behaviors of the materials. The developed approach is shown to be an efficient tool for the evaluation and prediction of the mechanical behavior of nanocomposite materials.
