A mechanical property evaluation of graded density Al-Si10-Mg lattice structures manufactured by selective laser melting (2016, background): “20 The manufacturing route for metal cellular solids has traditionally been to produce a foam and machine it to the required shape[8], or to stack and bond laminar sheets of periodic structures[9, 10].”
Impact response of additively manufactured metallic hybrid lattice materials (2017, methodology): “Investment casting methods enable complex lattice geometries to be produced (refer to [17] for a description 27 of this route).”
Structural performance of near-optimal sandwich panels with corrugated cores (2006, background): “An experimental and computational study of the bending response of steel sandwich panels with corrugated cores in both transverse and longitudinal loading orientations has been performed.”
Dynamic failure of metallic pyramidal truss core materials - Experiments and modeling (2006, methodology): “…were also performed on the tetragonal and pyramidal truss cores as well as truss-cored sandwich panels by Deshpande and Fleck (2001), Sypeck and Wadley (2002), Chiras et al. (2002), Wadley et al. (2003), Rabczuk et al. (2004), Xue and Hutchinson (2004), Rathbun et al. (2004), and Zok et al. (2004).”
The response of clamped sandwich plates with lattice cores subjected to shock loading (2006, methodology): “These cores were manufactured from 0.9 mm thick AL-6XN stainless steel sheets by first laser cutting square-cells to obtain a perforated sheet and then folding this perforated sheet node row by node row to obtain regular pyramids, see Wadley et al. (2003) for details of the manufacturing route.”
Additive manufacturing of metallic cellular materials via three-dimensional printing (2011, background): “[1, 3]) or an ordered repetition of a unit cell (e.g., joining crimped sheet metal into a corrugated form [ 8 ], bonding metal textile screen meshes [9], sand/investment casting trussed lattices [10], etc.[11]).”
