Finite Element Modelling and Analysis of Carbon Nanotobe Based Nano Composite Structures

Abstract

The objective of the present work is to finite element (FE) modelling and analysis of different nanocomposite structures such as airfoil and parabolic antenna for free vibration analysis (to find the different modal natural frequencies and mode shapes) as well as forced vibration analysis (to obtain the equivalent von Mises stresses and maximum transverse displacements). The analysis is done for Carbon Nanotube reinforced Composites with varying percentage of carbon nanotube content. First the mathematical model on Carbon Nanotube reinforced Composite was used to find out the different properties; i.e. Young's Modulus, Bulk modulus and so on with different volume fraction of Carbon Nanotube content present. Next step is to model the structures; i.e. airfoil and parabolic antenna by solid modelling and then covert it into Finite Element model by giving the proper meshing, conditions and input data. The FE model was then analysed with the help of ANSYS and the different mode shapes and fundamental vibration frequencies were found. The some important results were then presented into a table for comparison and discussion.
