Free vibration of FGM Lévy conical panels

Composite Structures, 2014
Abstract 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.

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.

The Dynamic Response of Cylindrical and Conical Panels

Journal of Applied Mechanics, 1969
The dynamic response of cylindrical and conical panels subjected to arbitrary time-varying load distributions is studied and appropriate equations are presented. Convenient trigonometric series are used, in conjunction with finite-difference methods, to reduce the governing equations to sets of matrix equations.

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

On the Response of Graphene Platelet Reinforced Composite Conical Panels Subjected to Mechanical Shock

SSRN Electronic Journal, 2022
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

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 ...

On the nonlinear dynamics of bimodular laminated composite conical panels

Nonlinear Dynamics, 2014
The 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 ...
