Bending behavior of corrugated-core sandwich plates

Composite Structures, 2005
Abstract In this paper, the comprehensive analysis for the linear behavior of a corrugated-core sandwich plate is presented. A closed-form solution based on the Mindlin–Reissner plate theory is presented to describe the behavior of corrugated-core sandwich plate bending with various boundary conditions.

Buckling and vibrations of metal sandwich beams with trapezoidal corrugated cores – the lengthwise corrugated main core

Thin-Walled Structures, 2017
Abstract The paper is devoted to the stability of an orthotropic multi-layered beam. This beam is an untypical sandwich structure the faces of which consist of three layers. The original mathematical model of the beam is formulated taking into account different properties of each layer.

Crashworthiness of hierarchical truncated conical shells with corrugated cores

International Journal of Mechanical Sciences, 2021
Abstract Novel corrugated hierarchical truncated conical shells (HTCS) with corrugated cores were designed for energy absorption under quasi-static axial compression. The crashworthiness of the HTCS were studied by experimental and numerical methods.

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.

Shear correction factors for corrugated core structures

Composite Structures, 2007
Because of the high computational cost involved when modeling a corrugated panel (in e.g., finite element analyses) the corrugated core sandwich is in this investigation homogenized and the panel is transformed to an equivalent continuous homogenous layer with effective equal properties.

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

Impact of carbon fibre/epoxy corrugated cores

Composite Structures, 2012
Abstract The dynamic compressive response of corrugated carbon-fibre reinforced epoxy sandwich cores has been investigated using a Kolsky-bar set-up. Compression at quasi-static rates up to v0 = 200 ms−1 have been tested on three different slenderness ratios of strut.

Shear buckling in the core of a corrugated board structure

Composite Structures, 2009
In some situations, a corrugated board package can experience loading of such a kind so that the corrugated core, or as it is most often referred to, the fluting, is loaded in transverse shear. This might cause the fluting to collapse and through this, cause a decrease in the bending stiffness.

Hierarchical Corrugated Core Sandwich Panel Concepts

Journal of Applied Mechanics, 2005
The transverse compression and shear collapse mechanisms of a second order, hierarchical corrugated truss structure have been analyzed. The two competing collapse modes of a first order corrugated truss are elastic buckling or plastic yielding of the truss members. In second order trusses, elastic buckling and yielding of the larger and smaller struts,
