Resilient 3D hierarchical architected metamaterials
Lucas R. Meza,Alex J. Zelhofer,Nigel J. Clarke,Arturo J. Mateos,Dennis M. Kochmann,Julia R. Greer +5 more
TL;DR: It is shown, through a combination of experiments and computations, that introducing hierarchy into the architecture of 3D structural metamaterials enables the attainment of a unique combination of properties: ultralightweight, recoverability, and a near-linear scaling of stiffness and strength with density.
