On the Elastic Stiffnesses of Corrugated Core Sandwich

Journal of Sandwich Structures & Materials, 2001
The objective of this paper is to review and recast previous analytical approaches to the analysis of the elastic stiffnesses of corrugated core sandwich panels into the framework of first-order shear deformation laminated plate theory. Extensional, shear and bending stiffnesses will be determined and compared to measured data. It is shown that the in-

Corrugated skin in a foam core sandwich panel

Composite Structures, 2009
Abstract Sandwich plates with one corrugated and one flat skin were studied with the goal to find configurations with higher strength and/or stiffness and reduced weight. A procedure for calculating homogenized orthotropic plate stiffnesses of the sandwich was developed and applied to a number of different profiles. The corrugations lead to increased

The shear response of lightweight corrugated core structures

Journal of Composite Materials, 2013
A combination of experimental, analytical and numerical techniques is used to characterise the shear response of lightweight corrugations based on glass fibre and carbon fibre reinforced epoxy resins. The corrugations were manufactured via a compression moulding procedure in which composite prepregs are cured between two serrated mould halves.

The mechanical behaviour of corrugated-core sandwich panels

Composites Part B: Engineering, 2013
A series of experimental investigations and numerical analyses is presented into the compression response, and subsequent failure modes in corrugated-core sandwich panels based on an aluminium alloy, a glass fibre reinforced plastic (GFRP) and a carbon fibre reinforced plastic (CFRP).

Precise bending stress analysis of corrugated-core, honeycomb-core and X-core sandwich panels

Composite Structures, 2012
Abstract A semi-analytical method for bending analysis of corrugated-core, honeycomb-core and X-core sandwich panels is presented. The real displacement of sandwich panels is divided into the global displacement field and local displacement field. The discrete geometric nature of the core is taken into account by treating the core sheets as beams and

Sound Transmission Across Sandwich Structures with Corrugated Cores

2014
An analytic study of sound transmission through all-metallic, two-dimensional, periodic sandwich structures having corrugated core is presented. The space-harmonic method is employed, and an equivalent structure containing one translational spring and one rotational spring per unit cell is proposed to simplify the analysis of the vibroacoustic problem.

Elastic constants for adhesively bonded corrugated core sandwich panels

Composite Structures, 2017
Abstract In this paper, the adhesively bonded corrugated core sandwich panel is introduced and its elastic properties are discussed. Due to the relative displacement and rotation between face and core plates in adhesive joints caused by adhesive layer distortion, traditional elastic constants with considering both face and core plates to be fastened ...

Strength optimization of ultralight corrugated-channel-core sandwich panels

Science China Technological Sciences, 2018
Novel ultralight sandwich panels, which are comprised of corrugated channel cores and are faced with two identical solid sheets, subjected to generalized bending are optimally designed for minimum mass. A combined analytical and numerical (finite element) investigation is carried out.

An equivalent plate model for corrugated-core sandwich panels

Journal of Mechanical Science and Technology, 2015
This paper suggests an equivalent plate model to analyze the mechanical behavior of corrugated-core sandwich panels under tensile and bending loads. A homogenization-based theory based on the equivalent energy method is used to obtain the stiffness matrices of corrugated cores of a sandwich panel.

Hybrid modes of the passive-core corrugated-waveguide laser

Canadian Journal of Physics, 1976
Coupled-mode theory is employed to obtain the threshold gains for oscillation on hybrid modes of a passive-core corrugated-waveguide laser pumped in a central portion of its length. Methods are developed for calculating intermode coupling coefficients and loss coefficients resulting from diffraction into any order of waveguide corrugations of ...
