TL;DR: In this paper, the positive support reaction is studied by means of analytical models, numerical analyses and experimental results, and the analyses result in recommendations for the design at the serviceability state.
Abstract: Interaction between the bending moment and support reaction introduces new failure modes at intermediate supports of continuous sandwich panels. Two different loading cases have to be separated in the design. Positive support reaction causes a compressive contact pressure between the supporting structure and sandwich panel, and negative support reaction tensile forces in the fasteners of the panels. In the paper, the loading case named the positive support reaction is studied by means of analytical models, numerical analyses and experimental results. The analyses result in recommendations for the design at the serviceability state.

TL;DR: In this article, the out-of-plane quasi-static compressive behavior of four types of corrugated cores (V-type, U-type and X-type) has been investigated by experiment and FE simulations.
Abstract: 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. The FE simulations predict the crush behavior of cores with reasonable accuracy and provide the whole progressive buckling process and deformation modes. Experiment and simulation indicate that the U-type core, V-type core and X-type core structures show excellent crushing resistance performance and energy absorption characteristic. The crush performance of the Y-type core structures is relatively poor because of bending mode.
