FREE VIBRATION OF THIN, ISOTROPIC, OPEN, CONICAL PANELS
Journal of Sound and Vibration, 1998This 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 ...

Nonlinear thermoelastic response of laminated composite conical panels
Structural Engineering and Mechanics, 2010Nonlinear 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 ...

Free Vibration of Bimodulus Laminated Cross-Ply Conical Panels
Volume 2: Automotive Systems; Bioengineering and Biomedical Technology; Computational Mechanics; Controls; Dynamical Systems, 2008The 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, 2003Based 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, 1999The 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

Vibration Characteristics of Conical Shell Panels With Three-Dimensional Flexibility
Journal of Applied Mechanics, 1999A 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 ...

Hygro-thermo-mechanical analysis of fiber-steered composite conical panels
Composite Structures, 2017Abstract Automated fiber placement (AFP) is one of the recently developed robot-assisted composite manufacturing techniques. Steering fibers along optimal curvilinear paths enables tailoring the multifunctional properties of laminated composites to fully exploit all potentials of composite materials.

On the nonlinear dynamics of bimodular laminated composite conical panels
Nonlinear Dynamics, 2014The nonlinear dynamics of bimodular laminated composite conical panels subjected to harmonic excitation is investigated using Bert’s constitutive model and first-order shear deformation theory based finite element. The governing equations of motion are solved to obtain the state vector representing the periodic response by employing shooting technique ...
