Abstract

There has been great interest inP recent years on Carbon Nanotube (CNT) based nanocomposites because of their superior mechanical properties, where stiffness, strength and resilience exceed any currently known material. In this paper, the effective elastic constants of long CNT-based nanocomposites are evaluated using a new 3D nanoscale hexagonal representative volume element (RVE). This study is based on continuum mechanics approach and uses FEM. Based on the theory of elasticity, formulae to determine the elastic constants for the RVE are derived for two loading cases. The effective Young's modulus in the axial direction of the RVE is calculated adopting the rule of mixtures which is applied for comparison with Finite Element Method (FEM) solutions.
