Flow-induced deformation of kirigami sheets

Webembedded array of cuts (i.e., a perforated sheet), by largely stretching it we form a system that comprises a periodic distribution of both cuts and folds (i.e., a kirigami sheet). In particular, we note that our kirigami sheets possess several deformation characteristics of the Miura-ori [2,3] and zigzag-base folded kirigami [12,13] (see movie ... WebWe investigate the deformation in a uniform water flow of thin sheets perforated with parallel cuts. Through combined experiments and theory, we show that deployment is governed by the competition between fluid forces and sheet stretchability, which is prescribed by the cut pattern. Importantly, fluid loading is modulated by the local three …
