WebIn this study, the ability to imbue honeycombs with a graded mechanical behaviour using origami techniques is investigated under dynamic loading. Grading is applied to the … WebJul 4, 2024 · A lower bound estimate of quasi-static strength and energy absorption was obtained using an analytical method by only considering the deformation mechanism of the rigid origami motion. Graded origami metamaterials were achieved by applying either a variation of the initial folding angle or a variation of the thicknesses of cell walls in the ...
Quasi-static and impact behaviour of foam-filled graded auxetic …
WebApr 10, 2024 · This paper aims to experimentally and numerically examine the behaviour of a novel re-entrant graded aluminium panel filled with PU foam in an auxetic pattern. The performance is assessed based on quasi-static and dynamic drop tower experiments supported by advanced non-linear finite element modelling. 2. WebDec 23, 2024 · With the increasing number of automobiles on the road, passive safety has become a particularly important issue. In this paper, an energy-absorbing material, origami aluminum honeycomb, was manufactured by a welding process for use as an automobile energy absorbing box.
