Low velocity impact of combination Kevlar/carbon fiber sandwich composites
TL;DR: In this article, the impact, compression after impact, and tensile stiffness properties of carbon fiber and Kevlar combination sandwich composites were investigated, and the experimental data in its entirety helps define the benefits and disadvantages of replacing carbon fiber layers with Kevlar or hybrid.
Journal ArticleDOI
Low velocity impact behavior of composite sandwich panels
TL;DR: In this article, the low velocity impact behavior of composite sandwich panels consisting of woven carbon/epoxy facesheets and a PVC foam core was studied experimentally and a straightforward peak impact load estimation method gave good agreement with experimental results.
Journal ArticleDOI
Failure Modes of Composite Sandwich Beams
TL;DR: In this article, a thorough stress analysis and applying appropriate failure criteria in critical regions of the beam is performed to predict tensile or compressive failure of the facesheets, debonding at the core/facesheet interface, indentation failure under localized loading, core failure, wrinkling of the compression facesheet, and global buckling.
Journal ArticleDOI
Flexural behaviour of structural fibre composite sandwich beams in flatwise and edgewise positions
TL;DR: In this article, the flexural behavior of composite sandwich beams made of glass fibre-reinforced polymer skins and modified phenolic core material was investigated and the results of the analytical predictions and numerical simulations are in good agreement with the experimental results.
Failure Modes in Composite Sandwich Beams
TL;DR: A thorough investigation of failure behavior of composite sandwich beams under three-and four-point bending was undertaken in this paper, where the beams were made of unidirectional carbon/epoxy facings and a PVC closed-cell foam core.

Finite Deflections of Sandwich Plates
TL;DR: In this article, the authors derived a system of differential equations for the small finite deflections of sandwich plates, which can be used to obtain plate-buckling equations that include the effect of transverse shear stress deformation on buckling loads.

Measurement of stress distribution in sandwich beams under four-point bending: Photoelastic investigation was made to study stress distribution in sandwich beams composed of various face and core under four-point bending, and multi-layer-builtup theory was applied to obtain the experimental results

TL;DR: The bending-stress distribution through thickness in sandwich-composite beams is different from those obtained by conventional composite-beam theory because of the shear effect of the core, especially when the ratio of elastic moduli of face to core (k=Ef/Ec) is large as discussed by the authors.

Large Deflections of Sandwich Plates: An experimental Investigation
TL;DR: In this article, a finite element analysis of the large deflection of clamped sandwich plates was performed and it was found that the non-linear behavior was more pronounced for strain than for deflection.
