【 摘 要 】

In the present work, by considering the agglomeration effect of single-walled carbon nanotubes, free vibration characteristics of functionally graded (FG) nanocomposite plates is presented. The volume fractions of randomly oriented agglomerated single-walled carbon nanotubes (SWCNTs) are assumed to be graded in the thickness direction. To determine the effect of CNT agglomeration on the elastic properties of CNT-reinforced composites, a two-parameter micromechanical model of agglomeration is employed. The effects of geometrical and material parameters on the frequency parameters of the FG nanocomposite plates are investigated. For an overall comprehension on 3-D vibration of rectangular plates, some mode shape contour plots are reported in this research work.
