Abstract An experimental–numerical methodology for the investigation of three point bending test (TPBT) on sandwich panels with Al skins and Nomex™ Honeycomb core is presented. A dedicated focus on numerical models is presented. Using data obtained from flatwise compressive tests, a highly detailed FE model (micromechanical level), has been built. It has, therefore, been possible to reproduce, with an elevated grade of similarity, the real behavior of sandwich panels in TPBT. Particular attentio...

This article deals with theoretical modeling of the local buckling in foam–core sandwich panels. This phenomenon is considered mainly in the periodic (unbounded wrinkle wave) and linearly elastic formulation. The analytical solutions are in agreement with results of finite element analysis and can be applied with a good precision for many finite-size panels, as well as for many sandwiches having honeycomb cores.

This paper describes a method to predict failure loads accurately in undamaged sandwich panels subject to bending. The current method of predicting failure loads using linear wrinkling models is limited. A general lack of correlation exists between experimental and analytical/numerical wrinkling models. In some cases, the linear wrinkling models over-estimate wrinkling failure loads in undamaged panels by 100%. Various authors have tried to account for this discrepancy by modifying their linear ...

Abstract This paper discusses the theoretical and quantitative design and analysis of a honeycomb panel sandwich structure. The initial design is based on specific requirements that the panel must achieve prior to failure under load. Materials to be used for the facing and core are selected based on the given requirements. With the materials chosen, the facing sheets and core are analyzed for failure. Failure occurs when the stresses in the panel exceed the properties of the materials by any mod...

The buckling behavior of a disbond in a sandwich beam is analyzed by modeling the sandwich as a beam on a Winkler foundation. The foundation stiffness is derived through a stress function approach, modeling the core as a two-dimensional, orthotropic material in plane strain. When the resulting stiffness term is used in the Winkler foundation model, the predicted buckling loads vary from the specimen test results by only 1.7% (with a standard deviation of 2.3%). This is the most accurate publishe...

Nonlinear mechanical behaviors of unidirectional composites were evaluated under compressive loading up to high-strain ranges using a sandwich beam specimen with the emphasis on the elastic material nonlinearity in the fiber direction. Specimen configuration and evaluation method, including material nonlinear effects, were proposed, and the compressive nonlinear behavior and strength of unidirectional carbon fiber reinforced composites were experimentally obtained. The measured compressive behav...

The overall performance of sandwich structures depends in general on the properties of the facesheets, the core, the adhesive bonding the core to the skins, as well as geometrical dimensions. Sandwich beams under general bending, shear and in-plane loading display various failure modes. Their initiation, propagation and interaction depend on the constituent material properties, geometry, and type of loading. Failure modes and their initiation can be predicted by conducting a thorough stress anal...

Abstract The objective of this study is to establish a bending strength prediction method for a thin CFRP face sheet / Nomex honeycomb sandwich panel, for which the failure mode is face-sheet / core debonding derived from local buckling of the face sheet. Stress and buckling eigenvalue analyses were conducted using a detailed core model reproducing honeycomb structure and a solid core model in which the core was homogenized as solid elements. In both the detailed model and the solid core model, ...

For high-speed trains (HSTs), interface failures often occur in their aluminum-PVC foam sandwich floor, the service life of which can affect the maintenance economy significantly. In this study, a floor model considering crushable foam layer and cohesive element was implemented to validate its bending behavior, with which the load-bearing capacity of actual floor structures under different loading conditions was analyzed. Accordingly, two strategies were presented for improving the load-bearing ...
