Structural performance of metallic sandwich beams with hollow truss cores
The article focuses on the structural performance of sandwich beams with hollow truss lattice cores made from a ductile stainless steel. The trusses are arranged in an orthogonal (cross-ply) configuration, in either ±45 (diamond) or 0 /90 (square) orientations with respect to the face sheets. The responses in shear, tension and compression, as well as simply supported and fully clamped bending,...
متن کاملOn 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...
متن کاملFem Analysis of Truss Hollow Section Joint
Truss structures are widely used in construction of large-scale buildings. Design of steel structures is standardised in detail through set of European standards called EUROCODE. One of these standards, ENV 1993-1-8 deals with design of joints, but it does not cover the design of conical element for reduction of circular hollow section to the joint. Finite element method was used in this paper ...
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...
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...
