Webtessellated kirigami cuts (green) shows markedly di˙erent tensile behaviour.Theinitialelasticityat<5%strain(Fig.2,purplesection) closely follows the deformation curve of the pristine sheet. As the applied tensile force exceeds a critical buckling force, the initially planar sheet starts to deform as the thin struts formed by the cuts Webat sheets with an embedded array of cuts can result in out-of-plane deformation [19{26]. However, while a wide range of 3D architectures have been realized by triggering …
