WebFeb 22, 2024 · FIG. 3: The buckling-induced Miura kirigami sheet (a) is at-foldable, (b) forms a saddle shape with a negative Gaussian curvature upon non-planar bending, (c) twists under anti-symmetric out-of-plane deformation (d) has much higher bending rigidity than the corresponding at perforated sheet (inset). Note that the 127 m thick Miura … WebKirigami technique, which is the Japanese art of paper cutting, turns inextensible sheets into ultra-stretchable structures through the opening up of the material [1] enabled by slits (figure1a). In a flow, kirigami sheets thus act as a poro-elastic surfaces : the structure deforms, opening pores which in turns affect fluid loading.
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 … Webior. Moreover, the sheet thickness significantly affects the transition from in-plane deformation to out-of-plane deforma-tion, and a thin sheet is prone to trigger mechanical instabil-ities with induced buckling, forming a variety of three dimensional (3D) architectures.19–22 The Kirigami approach
