Modeling of nanoplastic by asymptotic homogenization method

Abstract

The so-called nanoplastic is a new simple name for the polymer/layered silicate nanocomposite, which possesses excellent properties. The asymptotic homogenization method (AHM) was applied to determine numerically the effective elastic modulus of a two-phase nanoplastic with different particle aspect ratios, different ratios of elastic modulus of the effective particle to that of the matrix and different volume fractions. A simple representative volume element was proposed, which is assumed that the effective particles are uniform well-aligned and perfectly bonded in an isotropic matrix and have periodic structure. Some different theoretical models and the experimental results were compared. The numerical results are good in agreement with the experimental results.
