On a Novel Micromechanical Modeling of the Elastic Behavior of Nanocomposites

This work aims to the introduction of a new micromechanical modeling of the elastic behavior of nanocomposite materials with coated nanoparticles. The model is developed taking into account the interphase and particle clustering effects. The model is used to explain the relationship between mechanical properties of nanocomposites and their complex microstructure. Here we consider that the micromechanical modeling of the complex microstructure of nanocomposites requires the combination of the four-phase model and the three-phase model and we assume that all phases are elastic, isotropic and perfectly bonded. In this way, the effective elastic properties are derived using the integral equation and interfacial operators. In the micromechanical study, it was observed that the elastic modulus increases with the increasing in the volume fraction of nanoparticles. The effect of interphase zone is studied and the performance of the present model is showing by comparing with numerical and experiment results and show a good agreement.
