Nonsinusoidal Buckling Modes of Sandwich Plates

Journal of the Aeronautical Sciences, 1954
Both wrinkling and "quasi-Euler" buckling modes of sandwich plates have hitherto been taken as sinusoidal. In this report the possibility of nonsinusoidal modes is investigated. The core slab material considered is the special orthotropic one which does not resist deformation in its own plane, but only extension and shear­ ing perpendicular to its ...

Axisymmetric Vibration of Circular Sandwich Plates

AIAA Journal, 1974
Nomenclature p, pc = mass density of the face and core materials, respectively G, Gc = modulus of rigidity of the face sheet and core, respectively E, v = modulus of elasticity and Poisson's ratio of the face sheet h, 2c = thickness of face sheet and core, respectively u = radial displacement of midsurface of face sheet w = displacement in transverse ...

Higher-Order Finite Element for Sandwich Plates

AIAA Journal, 1998
A finite element model for the analysis of sandwich plates with laminated composites face-sheets is developed. In the model, the face-sheets are represented as ReissnerMindlin plates and therefore include shear deformation effects. The core is modelled as a three-dimensional continuum in which the through-thickness representation of the displacement ...

Deflection of Orthotropic Sandwich Plates

AIAA Journal, 1972
T paper presents a portion of the results of analytical and experimental studies on the deflection of simply-supported, transversely loaded, Orthotropic sandwich plates. Various core depths, face sheet thicknesses, and aspect ratios of the plate are treated in the investigation.

Comparison of elasticity and sandwich theories for a rectangular sandwich plate

The Aeronautical Journal, 1984
An elasticity solution is presented for the three layered all round simply supported rectangular plate subjected to a uniformly distributed normal load. Numerical results have been obtained by selecting parameters such that they are applicable for sandwich plates.

Note on Bending of Thick Sandwich Plates

Journal of the Aeronautical Sciences, 1951
BENDING THEORIES for homogeneous plates are of three types, which essentially depend upon the thickness of the plate, h, relative to either the deflection, 8, or a characteristic length, I: (a) Linear bending theory for thin plates is used when the deflections and thickness are small—i.e., 8/h

Vibration Control of Sandwich Plates

Applied Mechanics and Materials, 2014
This paper presents the active control of vibrations of sandwich plates using piezoelectric composites (PZC). The top surface of the plate is integrated with the patches of active constrained layer damping treatment. Active fiber composite, one of the commercially available PZCs, is used as the material of the constraining layer of the patches and the ...

Theory of Sandwich Plates

1999
The object of this chapter is to establish the equations for the mechanical behavior of sandwich plates. A sandwich material (Chapter 3) is made from a material of low density (the core) having face sheets (the skins), made of plates or laminates bonded to each of the surfaces. The essential function of the core is to transfer, by transverse shear, the

Acoustic behavior of sandwich plates

Journal of Sandwich Structures & Materials, 2014
Sandwich structures of honeycomb cores and carbon laminate face sheets are ideal to meet low-weight and high-stiffness specifications. However, these structures are susceptible to noise problems. They tend to radiate structure-borne sound very efficiently or be transparent for air-borne sound.

The Effect of a Slow Impact on Sandwich Plates

Journal of Composite Materials, 2002
The purpose of this paper is to study the relation between the impact force and the corresponding elastic indentation produced by a rigid sphere falling on a sandwich plate. The analysis of the problem is articulated in three steps. Firstly, an explicit elastic solution for a sandwich panel, statically loaded by a distribution of surface pressures ...
