Buckling of multi-annular plates

Computers & Structures, 1986
Buckling of multi-annular plates is considered. The plate is loaded by axisymmetric radial in-plane forces, either at the outer edge or at one of the circumferential joints or a combination of the two. The plate is simply supported or clamped at the outer boundary or at one of the common joints.

FREE VIBRATIONS OF ANNULAR PLATES COUPLED WITH FLUIDS

Journal of Sound and Vibration, 1996
Summary: The natural frequencies of annular plates on an aperture of an infinite rigid wall and in contact with a fluid on one side are theoretically obtained by using the added mass approach. The fluid is assumed to be incompressible and inviscid and the velocity potential describes its irrotational motion. The Hankel transform is applied to solve the

Transverse Vibration of Thick Annular Sector Plates

Journal of Engineering Mechanics, 1993
This paper investigates the free vibration of thick sector plates with different supporting edge conditions. The Rayleigh-Ritz procedure is used in the energy functional, which includes the effect of shear deformation and rotatory inertia in deriving the governing eigenvalue equation.

Vibration of Annular Mindlin Plates with Small Cores

Journal of Engineering Mechanics, 2007
In most publications on vibration of annular plates, the natural frequencies are only presented for inner radius as small as one-tenth of its outer radius, but there are hardly any results presented for cores smaller than this inner radius value. This is attributed to severe scaling problems upon using numerical techniques to obtain the fundamental ...

Axisymmetric Buckling of an Annular Plate

1973
The problem of the stability of annular plates is common, especially in aeronautical engineering where there is a need to create circular holes in compressed plates. The purpose of such holes may be to minimize the weight of the vehicle or to provide access, to pass cables and pipes and so on.

Hydroelastic Vibration of Free-Edge Annular Plates

Journal of Vibration and Acoustics, 1997
This paper is concerned with the virtual mass effect due to the presence of water on the natural frequencies of free-edge annular plates resting on free surface or completely submerged, which has never been studied theoretically. Experiments were carried out for free-edge annular plates to find the so-called nondimensionalized added virtual mass ...

On the Vibration of Thick Annular Plates

1987
The vibrations of thick annular plates with various boundary conditions on the inner and outer boundaries are treated by several methods. One method is the well known Mindlin Plate Theory in which the effects of shear and rotary inertia are included.

Numerical and Asymptotic Modeling of Annular Plate Vibrations

2013
Free axisymmetric flexural vibrations of an annular elastic thin plate are studied. Numerical solutions of eigenvalue problem for various boundary conditions are obtained. The plate can be used as a model of the supporting frame of a shell. In this connection the boundary conditions corresponding the attaching of the plate to a cylindrical shell are ...

VIBRATION OF THE CIRCULAR ANNULAR PLATE WITH

2014
Circular annual plate hinged fixed on an internal circuit which is jammed and free. For the decision of task the Bessel function of different sort of a zero and first order are used . For every form of vibrations, n  0 , 1, 2 worked out frequency equations and equalization for determination of position of nodal circumferences.
