Compression behavior of a novel sandwich structure with bi-directional corrugated core

, 2021
A novel sandwich structure with bi-directional corrugated core is designed and manufactured by 3D-printing. Initial attention focuses on the compression response and failure modes of this new structure.

Experimental crashworthiness analysis of corrugated-core sandwich panels under impact loading

Ships and Offshore Structures
This research scrutinizes and contrasts the crashworthiness of single-core and two-core corrugated sandwich panels with varying configurations, influenced by crucial parameters like thickness, core angle, and foam filling.

On the nonlinear buckling and postbuckling responses of sandwich FG‐GRC toroidal shell segments with corrugated core under axial tension and compression in the thermal environment

Polymer Composites
This paper presents an analytical approach for buckling and postbuckling analysis for functionally graded graphene‐reinforced composite (FG‐GRC) toroidal shell segments with the trapezoidal or round corrugated core under the axial tension and compression.

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 ...

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-

Dynamic response of clamped sandwich beams with foam-filled sinusoidal corrugated core subjected to low-velocity impact

Mechanics of Advanced Materials and Structures
Sandwich structure is a lightweight structure with high specific strength and specific stiffness, as well as excellent energy absorption and load-carrying capacity. Sandwich structures are widely used in aerospace, high-speed rail and marine applications.

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
