Researchers in the US have broken the world record for the lightest structural material. The metal-based microlattice structures are significantly less dense than the rarest aerogels and other ultralight foams, while exhibiting high strength and an unexpectedly high ability to absorb energy and recover ...

[ 2 ] Absorption of large impact energies in car bumpers or light-weight bicycle hel-mets is based on destructive modif i cations of foams or metal structures, i.e., the required function can be obtained only once. [ 3 ] For example, commercially available aluminum foams (honeycomb ...
Plasticity of formable all-metal sandwich sheets: Virtual experiments and constitutive modeling[J]. International Journal of Solids and Structures, 2012, 49(19/20): 19−20. [28] BESSE C C, MOHR D. Optimization of the effective shear properties of a bidirectionally corrugated sandwich core ...
the electrical conductivity was measured by a two-electrode method and two metal wires were used as the current collectors. To optimize the electrical contact between conductive copper face sheets and aerogel, each end of the aerogel was carefully affixed to copper sheet with a thin layer of silv...
3D printed metal lattice structures such as these have so many exciting applications and this work allows us to better understand their properties and design lattices that can be used in real world applications with confidence in their failure modes, mechanical properties and reliability in general"...
