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-

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 ...

Flutter of functionally graded open conical shell panels subjected to supersonic air flow

Proceedings of the Institution of Mechanical Engineers, Part G: Journal of Aerospace Engineering, 2012
In this article, analysis of supersonic flutter of functionally graded open conical shell panels with clamped and simply supported edges is presented. The aeroelastic stability problem is formulated based on first-order shear deformation theory as well as classical shell theory and solved using Galerkin method.

Higher order static analysis of truncated conical sandwich panels with flexible cores

Steel and Composite Structures, 2015
A higher order analytical solution for static analysis of a truncated conical composite sandwich panel subjected to different loading conditions was presented in this paper which was based on a new improved higher order sandwich panel theory. Bending analysis of sandwich structures with flexible cores subjected to concentrated load, uniform distributed

Improved Flat Frequency Response of Conical Shellular Metamaterial‐Enabled Flat Panel Loudspeaker

Advanced Materials Technologies
AbstractA piezoelectric flat panel loudspeaker operates by utilizing a piezoelectric film actuator to vibrate a diaphragm, offering advantages in miniaturization, embedding, and spatial efficiency. However, achieving high sound pressure levels (SPL) at low frequencies and maintaining a flat frequency response remains challenging.
