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.

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.

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.

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.

Elasto-Plastic Analysis of Corrugated-Core Sandwich Plates

Mechanics of Advanced Materials and Structures, 2006
In this paper, the elasto-plastic analysis of corrugated-core sandwich panels is developed. The developed study is based on the incremental theory of plasticity with the initial incremental plastic moments calculated by the iterative procedure. The yield criterion is proposed for the structurally orthotropic 2D sandwich plates.

Buckling Tests for Laser-Welded Single Corrugated Core

Key Engineering Materials, 2018
This study was employed to investigate the buckling effect for a single Vf corrugated core. Brief and simple designing method is developed for UHS sandwich structure. This method is based on simplified calculation of slenderness ratio integrated with FEM simulation.

Impact resistance of composite circular corrugated core sandwich structures

Journal of Composite Materials, 2022
In this study, we used HyperMesh and LS-DYNA software, based on the MAT54 model and Chang-Chang failure criterion, to establish a finite element model of composite corrugated sandwich structures, and introduced a progressive damage model. The impact resistance of the corrugated sandwich structure was studied by analysing the residual velocity of the ...
