Penetration and Perforation of Composite Sandwich Panels by Hemispherical and Conical Projectiles

Journal of Pressure Vessel Technology, 1998
The 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, 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 ...

Bending analysis of moderately thick functionally graded conical panels

Composite Structures, 2011
Abstract Considering the application of functionally graded (FG) materials in various industries, the present study aims to investigate bending of moderately thick clamped FG conical panels subjected to uniform and non-uniform distributed loadings. Effective mechanical properties which are vary from one surface of the panel to the other assumed to be

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 ...

Free vibration study of composite conical panels reinforced with FG-CNTs

Engineering Structures, 2018
Abstract This work analyses the natural frequencies of composite conical panels made of a polymeric matrix reinforced with uniform or functionally graded carbon nanotubes (FG-CNTs). The mechanical properties of the composite conical panels rely on a refined rule of mixtures, including some efficiency parameters, whereas the kinematics of the problem ...

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
