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

Influence of buckling temperature on free vibration behavior of the conical panel
Materials Today: Proceedings, 2021Abstract The present work addresses the changes occurring in buckling strength and natural frequency of a conical panel with thermal loads using finite element methods. First, the critical temperature of the conical panel at which the buckling occurs is computed, followed with pre-stressed modal analysis.

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.

Supersonic flutter analysis of FGM shallow conical panel accounting for thermal effects
Meccanica, 2017Supersonic flutter behaviors of functionally graded material (FGM) shallow conical panel with steady thermal stress are investigated. It is assumed that temperature dependent material properties are graded along the radial direction following power law form.

Determination of critical buckling loads of isotropic, FGM and laminated truncated conical panel
Composites Part B: Engineering, 2016Abstract 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.

Free vibration of FGM Lévy conical panels
Composite Structures, 2014Abstract Free vibration analysis of open conical panels made of through-the-thickness functionally graded materials (FGMs) is analyzed in this research. Mechanical properties of the shell are distributed across the thickness based on the power law function.

Dynamic analysis of stiffened conical shell panels
Computers & Structures, 1989The present paper deals with the dynamic response analysis of stiffened conical shell panels using an integral equation method in the space domain. The smearing technique is used for closely spaced stiffeners. The time domain analysis has been done using the mode superposition method. The effect of eccentricity of stiffeners has been studied.

Current investigation deals with the dynamic response of composite conical panels which are subjected to mechanical shock. It is assumed that composite laminated conical panel is reinforced with graphene platelets (GPLs) where the amount of GPLs may be different in the layers. As a result, a piecewise functionally graded media may be achieved. To model
