On the performance of truss panels with Kagomé cores (2003, background): “Recent assessment of ultra-light metallic systems has revealed that periodic truss core panels exhibit superior thermo-structural characteristics (Wicks and Hutchinson, 2001; Wallach and Gibson, 2001; Deshpande et al., 2001; Evans et al., 2001; Deshpande and Fleck, 2001; Chiras et al., 2002).”
Lattice truss structures from expanded metal sheet (2007, methodology): “For lattices with more slender trusses, the peak compressive strength is controlled by buckling of the lattice truss members [4].”
Compressive behavior of age hardenable tetrahedral lattice truss structures made from aluminium (2004, background): “…the density of the core to the density of the solid from which it is made) for a core occupying 50% of the available tetrahedral sites is given by [6] q ¼ 2 ffiffi ffi 3 p 1 cos 2 x Á sin x t l 2 ; ð1Þ where x is the angle between the truss members and the base tetrahedron and t and l are the…”
