Simulated properties of Kagom e and tetragonal truss core panels
نویسندگان
چکیده
The finite element method has been used to simulate the properties of panels with Kagom e and tetragonal cores under compressive and shear loading. The simulation has been performed for two different materials: a Cu-alloy with extensive strain hardening and an Al-alloy with minimal hardening. It is shown that the Kagom e core is more resistant to plastic buckling than the tetragonal core under both compression and shear. One consequence is that the Kagom e structure has the greater load capacity and a deferred susceptibility to softening. Another is that the Kagom e core is isotropic in shear: contrasting with the soft orientations exhibited by the tetragonal core. 2003 Elsevier Ltd. All rights reserved.

On the performance of truss panels with Kagom e cores
The performance characteristics of a truss core sandwich panel design based on the 3D Kagom e has been measured and compared with earlier simulations. Panels have been fabricated by investment casting and tested in compression, shear and bending. The isotropic nature of this core design has been confirmed. The superior performance relative to truss designs based on the tetrahedron has been demo...

In this paper, a new roofing system is introduced, which is constructued using the precast composite sandwich panels. This roofing sandwich panels system consists of three kinds of precast concrete sandwich panels including capital panels, beam or between columns panels, and slab or middle panels. The panels are composed of three layers; A high strength reinforced concrete top layer. A thick la...
متن کاملThe structural performance of near-optimized truss core panels
Theoretical studies have indicated that truss core panels with a tetragonal topology support bending and compression loads at lower weight than competing concepts. The goal of this study is to validate this prediction by implementing an experimental protocol that probes the key mechanical characteristics while addressing node eccentricity and structural robustness. For this purpose, panels have...
متن کاملA protocol for characterizing the structural performance of metallic sandwich panels: application to pyramidal truss cores
All-metallic sandwich panels with truss and prismatic cores have impending application as ultra-light load bearing panels amenable to simultaneous active cooling and blast resistance. To facilitate application, a protocol for characterizing the structural performance of such panels is needed that can be used for design calculations. An approach capable of realizing this objective is presented a...
متن کاملShear and bending performance of carbon fiber composite sandwich panels with pyramidal truss cores
Structural performance in direct (pure) shear and three-point bending was investigated for sandwich panels with a carbon fiber pyramidal truss core. Analytical estimates for sandwich panel strength for each loading condition were presented for possible competing failure modes. In the experimental part of the study, pyramidal truss cores were made using the hot press molding technique and then a...
