Combinatorial design of textured mechanical metamaterials

Corentin Coulais, Eial Teomy, Koen de Reus, Yair Shokef, Martin van Hecke
2016 Nature  
Here we introduce a combinatorial strategy for the design of aperiodic yet frustration-free mechanical metamaterials, whom we show to exhibit spatially textured functionalities.  ...  The structural complexity of metamaterials is limitless, although in practice, most designs comprise periodic architectures which lead to materials with spatially homogeneous features.  ...  As spins at the surface of a metamaterial represent its texture of bumps and dents, this implies that textures at opposite faces of a metacube are directly linked.  ...
