“…2.2 are summarised in Table. The experimental methods are discussed in Ref. [7] and some preliminary results were given in Ref. [8].…”

Unraveling metamaterial properties in zigzag-base folded sheets

“…Consequently, availability of large design motifs can be advantageous, for instance, in dynamic architectural façades where the place of the holes in the patterns can be controlled by combining Miura-ori with BCHn to either allow light in the interior of the building or to promote shading when desirable. In Summary, the remarkable properties of the patterns (specifically BCH2), such as rigidfoldability, flat-foldability, and possessing single DOF, as well as numerous possible combinations of the patterns make them potentially suited for a broad range of applications including kinetic and deployable structures (e.g., solar sails [24]), light cellular foldcore sandwich panels [25,26], 3D tunable folded cellular metamaterials [1,4,34], energy absorbing devices [35], foldable robots [36] and auxetic materials [28,29]. In all these applications, scalability is a major feature of the BCHn or other combined patterns (due to their inherent geometric properties).…”

“…Moreover, it has been reported that self-organized wrinkling pattern for a planar stiff thin elastic film connected to a soft substrate subjected to biaxial compression is a herringbone pattern which is similar to the Miura-ori pattern [19,20,21]; and that the herringbone pattern corresponds to the minimum energy configuration [22]. Applications of the Miura-ori pattern range from folding of maps [23] to technologies such as deployable solar panels [24], foldcore sandwich panels [25,26], and metamaterials [1,3].…”
