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,

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.

Energy absorption of foam-filled corrugated core sandwich panels under quasi-static loading

Proceedings of the Institution of Mechanical Engineers, Part L: Journal of Materials: Design and Applications, 2022
The present paper tries to introduce the effect of foam-filled on a type of trapezoidal corrugated core and their structures derived from the related previous studies. The main purpose of this work is to present a novel geometry of trapezoidal cores, and

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.

Inertial amplification induced band gaps in corrugated-core sandwich panels

Composite structures, 2021
Corrugated-core sandwich panels (CSPs) have numerous applications but suffer from poor vibration performance in low-frequency range. To address this issue, a type of four-bar inertial amplification (IA) mechanism, whose inertia is increased by amplifying

Crush Behavior of Corrugated Cores Sandwich Panels

Advanced Materials Research, 2011
The out-of-plane quasi-static compressive behavior of four types of corrugated cores (V-type, U-type, X-type and Y-type core) has been investigated by experiment and FE simulations. By transient dynamic finite element analysis code MSC.Dytran numerical simulations were performed for calculating crushing forces, deformation mode and energy absorption ...

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.

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.

An analytical study of the effects of a circumferentially corrugated core on sound transmission through double-walled cylindrical shells

Journal of Vibration and Control, 2022
Corrugated structures are widely being used in industrial applications, which raises the demand for careful analysis of their behavior. To fill the gap for vibroacoustic characteristics, this paper focuses on proposing a model to investigate sound ...
