Vibration Analysis of Functionally Graded Nanocomposite Conical Shell Structures

Patel, Mrityunjay Prasad (2015) Vibration Analysis of Functionally Graded Nanocomposite Conical Shell Structures. MTech thesis.



The present work deals with the free vibration analysis and buckling behavior of functionally graded nanocomposite conical shell structures reinforced with carbon nanotubes. The effective material properties of the functionally graded nanocomposite shell structures are obtained using the extended rule of mixture by using UD and some functionally graded distribution of singlewalled carbon nanotubes (SWCNTs) in the thickness direction of the shell. In this study the nanocomposite is forming by mixing SWCNTs as reinforced phase with the polymer as matrix phase and makes a superior quality nanocomposite material at nanoscale level with some extraordinary material properties which provides advanced performance and service level. A suitable finite element model of functionally graded conical shell structure is developed using the ANSYS parametric design language (APDL) code in ANSYS environment. The model has been discretized using an eight noded shell element. The solution is obtained for fundamental natural frequencies and deformation of the composite shell. The effects of various geometric parameters, CNT volume fraction, boundary conditions and material properties are presented and discussed
