Vibration and Mode Shape Analysis of Functionally Graded Nanocomposite Plates Reinforced by Aggregated Carbon Nanotube

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.
