| description | Uniform dispersion of carbon nanotubes (CNTs) is a key issue for utilization of their reinforcement
potential in CNT-reinforced metal matrix nanocomposites (MMNCs). It was reported that CNT clusters often
exist in MMNCs prepared by various techniques, which reduces the load transfer efficiency between the matrix
and reinforcement. In this paper, a new micromechanical constitutive model of CNT-reinforced MMNCs is
developed, which takes into account of the influences of CNT clusters and misorientations. The strength values
of a CNT/Al nanocomposite predicted by the new model are compared first with experimental data for
validation. Then, the developed model is applied to predict the size effect, temperature effect and strain rate
effect of the nanocomposite in its overall elastoplastic response. |
