Parametric study of CNT waviness effect in CNT/polymer nanocomposites using multiscale finite element modeling
Surendra Kumar
Abstract
The effect of CNT waviness on the elastic properties of CNT-reinforced polymer nanocomposites is investigated using multiscale finite element modeling. CNT and the interphase are modeled at the nanoscale as discrete structures of beams and trusses, and the polymer matrix is treated as a microscale continuum medium. Using the model, a parametric study of the effect of CNT waviness is carried out. The effect of CNT waviness is also calculated using a three-phase Mori-Tanaka micromechanical model, and the results are compared. The model is validated with molecular dynamics simulation results and experimental data available in the literature.
