Bending analysis of moderately thick functionally graded conical panels

Composite Structures, 2011
Abstract Considering the application of functionally graded (FG) materials in various industries, the present study aims to investigate bending of moderately thick clamped FG conical panels subjected to uniform and non-uniform distributed loadings. Effective mechanical properties which are vary from one surface of the panel to the other assumed to be

Free Vibration of Bimodulus Laminated Cross-Ply Conical Panels

Volume 2: Automotive Systems; Bioengineering and Biomedical Technology; Computational Mechanics; Controls; Dynamical Systems, 2008
The problem is formulated employing first order shear deformation theory. The governing equations, obtained using Lagrange’s equation of motion, are solved by finite element method. A detailed parametric study is carried out to study the influences of thickness ratio, aspect ratio, semicone angle, and number of layers on the free vibration natural ...

Frequency Analysis of Rotating Conical Panels: A Generalized Differential Quadrature Approach

Journal of Applied Mechanics, 2003
Based on the generalized differential quadrature (GDQ) method, this paper presents, for the first instance, the free-vibration behavior of a rotating thin truncated open conical shell panel. The present governing equations of free vibration include the effects of initial hoop tension and the centrifugal and Coriolis accelerations due to rotation ...

AN h–p FINITE ELEMENT VIBRATION ANALYSIS OF OPEN CONICAL SANDWICH PANELS AND CONICAL SANDWICH FRUSTA

Journal of Sound and Vibration, 1999
The vibration study of a general three-layer conical sandwich panel based on the h-p version of the finite element method is presented in this paper. No restriction is placed on the degree of curvature of the shell, thereby relaxing the strictures associated with shallow shell theory. The methodology incorporates a new set of trigonometric functions to

On the free vibration characteristics of multiscale hybrid conical panels utilizing Chebyshev–Ritz route

Mechanics based design of structures and machines
This study investigates the vibrational behavior of three-phase polymer-glass fiber (FG)-carbon nanotubes (CNT) nanocomposites conical panels. Effects of the wavy shape of CNTs and the viscoelastic nature of the polymer matrix are considered.

Vibration Characteristics of Conical Shell Panels With Three-Dimensional Flexibility

Journal of Applied Mechanics, 1999
A first known investigation on the three-dimensional vibration characteristics of conical shell panels is reported. A linear frequency equation is derived based on an exact three-dimensional, small-strain, linearly elastic theory. Sets of one and two-dimensional polynomial series are employed to approximate the spatial displacements of the conical ...

GENERALIZED DIFFERENTIAL QUADRATURE METHOD FOR THE FREE VIBRATION OF TRUNCATED CONICAL PANELS

Journal of Sound and Vibration, 2002
Summary: We present an improved generalized differential quadrature (GDQ) method for the investigation of the effects of boundary conditions on the free vibration characteristics of truncated conical panels. The truncated conical panel is an important geometrical shape in the fields of aerospace, marine and structural engineering. However, despite this
