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 ...

Penetration and Perforation of Composite Sandwich Panels by Hemispherical and Conical Projectiles
Journal of Pressure Vessel Technology, 1998The results of penetration and perforation tests carried out on composite sandwich panels with GRP skins and PVC foam cores using hemispherical-ended and conical-nosed indenters/projectiles under quasi-static, drop-weight, and ballistic impact conditions, with impact velocities up to 305 m/s, are described. Load-displacement characteristics under quasi-

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 ...

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.

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 ...
