The variation of the stiffness coefficients for laminated open conical shell panels

Composite Structures, 1995
Abstract To date, all analyses of laminated conical shells have been undertaken using constant stiffness coefficients in the laminate constitutive equations. In this paper, it is shown that the geometry of a conical surface actually renders the stiffness coefficients a function of circumferential location; they are not strictly constant, as has ...

A numerical study on the free vibrations of nanocomposite conical panels with variously shaped cutout

The European Physical Journal Plus, 2021
Presented herein is a novel numerical approach for the vibrational analysis of conical panels with arbitrary-shaped holes made of functionally graded graphene platelet-reinforced composite (FG-GPLRC) within the framework of higher-order shear deformation theory (HSDT).

EFFECTS OF SUBTENDED AND VERTEX ANGLES ON THE FREE VIBRATION OF OPEN CONICAL SHELL PANELS: A CONICAL CO-ORDINATE APPROACH

Journal of Sound and Vibration, 1999
This paper presents a computational investigation on the effects of subtended and vertex angles on the free vibration characteristics of open conical shell panels. Unlike the conventional approximation using a rectangular or cylindrical co-ordinate system, this analysis adopts a natural conical co-ordinate system so that any approximation in geometry ...

An element‐free analysis of mechanical and thermal buckling of functionally graded conical shell panels

International Journal for Numerical Methods in Engineering, 2010
AbstractThis paper presents a mechanical and thermal buckling analysis of metal and ceramic functionally graded conical shell panels using the element‐free kp‐Ritz method. The formulation is based on the first‐order shear deformation shell theory, which accounts for the transverse shear strains and rotary inertia, and mesh‐free kernel particle ...

Nonlinear Dynamics of FGM Conical Panel With Initial Imperfection in Thermal Environment

Volume 6: 13th International Conference on Multibody Systems, Nonlinear Dynamics, and Control, 2017
In this paper, the nonlinear dynamics of a simply supported functionally graded materials (FGM) conical panel with different forms of initial imperfections is investigated. The conical panel is subjected to the simple harmonic excitation along the radial direction and the parametric excitation in the meridian direction.

Hygro-thermo-mechanical analysis of fiber-steered composite conical panels

Composite Structures, 2017
Abstract 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.

Buckling analysis of cross-ply laminated conical panels using GDQ method

Composites Part B: Engineering, 2013
Abstract The buckling analysis of cross-ply laminated conical shell panels with simply supported boundary conditions at all edges and subjected to axial compression is studied. The conical shell panel is a very interesting problem as it can be considered as the general case for conical shells when the subtended angle is set to 2π and also cylindrical

Determination of critical buckling loads of isotropic, FGM and laminated truncated conical panel

Composites Part B: Engineering, 2016
Abstract The present study deals with buckling analysis of simply supported conical panels based on the Donnell's shell theory. Different material properties have been considered such as isotropic, composite laminated and functionally graded (FG). The governing differential equation for buckling of laminated conical panel is derived.

Vibration analysis of conical panels using the method of discrete singular convolution

Communications in Numerical Methods in Engineering, 2006
AbstractA discrete singular convolution (DSC) free vibration analysis of conical panels is presented. Regularized Shannon's delta kernel (RSK) is selected as singular convolution to illustrate the present algorithm. In the proposed approach, the derivatives in both the governing equations and the boundary conditions are discretized by the method of DSC.
