Flow-induced deformation of kirigami sheets
WebFeb 24, 2024 · Abstract: We investigate the mechanical response of thin sheets perforated with a square array of mutually orthogonal cuts, which leaves a network of squares … WebJan 26, 2024 · Compared to continuous thin sheets, the kirigami sheet enables more freedom and flexibility in shape shifting through local or global deformation between cut units 17. Starting from a thin sheet with patterned cuts, it can morph into varieties of 2D and pop-up 3D structures via rigid rotation mechanism 20 and/or out-of-plane buckling 21.

(E) WebContext: The work will be mostly experimental, characterizing the flow-induced deformation of kirigami sheets with generic slit patterns (involving imaging techniques, …
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 … 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 …
