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.

Acoustic radiation characteristics of un-baffled laminated composite conical shell panels
Materials Today: Proceedings, 2018Abstract This article presents a study on the vibro-acoustic behavior of laminated composite conical shell panels subjected to harmonic point excitation. The shell panel model is developed in the framework of the first order shear deformation theory using commercial software package ABAQUS.

Dynamic response of layered conical shell panel using integral equation technique
Computers & Structures, 1989In this paper, the application of integral equation technique to dynamic response problem has been illustrated by considering the layered conical shell panel. The method consists of using the integral equation technique in the space domain and direct integration using the Wilson-theta method in the time domain.

Effect of Bimodularity on Dynamic Response of Cross-ply Conical Panels
International Journal of Aerospace Innovations, 2010The 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

The variation of the stiffness coefficients for laminated open conical shell panels
Composite Structures, 1995Abstract 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 ...

Bending analysis of moderately thick laminated conical panels with various boundary conditions
Proceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science, 2011Bending analysis of moderately thick laminated conical panels with various boundary conditions is presented using the generalized differential quadrature (GDQ) method. Different combinations of clamped, simply supported, and free boundary conditions are considered.

Nonlinear Dynamics of FGM Conical Panel With Initial Imperfection in Thermal Environment
Volume 6: 13th International Conference on Multibody Systems, Nonlinear Dynamics, and Control, 2017In 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.

Thermal effect on free vibration of functionally graded truncated conical shell panels
Thin-Walled Structures, 2016Abstract The influences of thermal environment on the free vibration characteristics of functionally graded (FG) truncated conical panels are investigated based on the first-order shear deformation theory (FSDT). By taking into account both the temperature dependence of material properties, which are assumed to be graded in the thickness direction ...
