Quasi-Static Compressive Behavior of Tetrahedral Lattice Truss Structures Made from Aluminium

Compressive behavior of age hardenable tetrahedral lattice truss structures made from aluminium

Open cell, lattice truss structures have been made by folding perforated 6061 aluminium alloy sheets. Simple air brazing is used to construct sandwich panels with cellular core relative densities between 0.02 and 0.08. Some panels were quenched and aged while others were tested in an annealed condition. The measured peak compressive strengths varied from 0.7 to 20 MPa, increasing with core rela...

Lattice truss structures from expanded metal sheet

Metallic lattice truss structures are usually made by perforating a metal sheet with a periodic diamond pattern followed by folding at node rows to create a plate of 3D interconnected trusses. For low relative density lattices, the initial sheet material is inefficiently utilized, and the node area is small raising concerns about node bond robustness under shear or tensile loading. Here, we exp...

The Investigation of Modelling Material Behavior in Autofrettaged Tubes Made from Aluminium Alloys

Normal 0 false false false EN-US X-NONE AR-SA The ratio of compression yield strength to the initial tensile yield strength is called Bauschinger effect factor, BEF. A nonlinear strain hardening mathematical model is proposed for 7075 aluminium alloy (A7075). Uniaxial tension-compression experimental data are used to figure out a suitable model to study the BEF. Hence, uniaxial tension-co...

The Effect of Viscous Dampers on Improvement of the Behavior of Tall Belt Truss Structures

Using energy absorption systems in the structures with malfunctioning components is of paramount importance. By absorbing the seismic energy, these systems help the components of the structure to remain resilient during earthquake. In the present study, viscous dampers were applied in order to enhance the reactions of tall building with belt truss. To assess the response of a structure un...
