FREE VIBRATION OF THIN, ISOTROPIC, OPEN, CONICAL PANELS

Journal of Sound and Vibration, 1998
This paper describes a general analysis of the vibration characteristics of thin, open, conical isotropic panels using theh-pversion of the finite element method in conjunction with Love's thin shell equations. The convergence properties of this element have been established for particular geometries, thereby endorsing its suitability for use in ...

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 ...

Buckling of functionally graded conical panels under mechanical loads

Composite Structures, 2012
Abstract This paper presents an analytical approach to investigate the linear buckling of truncated conical panels made of functionally graded materials and subjected to axial compression, external pressure and the combination of these loads. Material properties are assumed to be temperature-independent, and graded in the thickness direction ...

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 ...
