Nonlinear thermoelastic response of laminated composite conical panels

Structural Engineering and Mechanics, 2010
Nonlinear thermoelastic static response characteristics of laminated composite conical panels are studied employing finite element approach based on first-order shear deformation theory and field consistency principle. The nonlinear governing equations, considering moderately large deformation, are solved using Newton-Raphson iterative technique ...

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

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 ...

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.

Effect of Bimodularity on Dynamic Response of Cross-ply Conical Panels

International Journal of Aerospace Innovations, 2010
The effect of bimodularity ratio on free vibration characteristics of cross-ply conical panels of various geometry and lamination scheme is studied. Forced vibration response is also studied for a typical case. The formulation is based on first order shear deformation theory and Bert’s constitutive model. An iterative eigenvalue approach is employed to

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 ...
