WebIn Fig. 1 C and D, we show snapshots of the kirigami sheet and kirigami shell at different levels of applied deformation. We find that the responses of the two structures are remarkably dif-ferent (Movie S3). In the kirigami sheet at a critical strain, all triangular features simultaneously pop up, forming a uniform 3D Significance WebA particular kirigami two-dimensional (2D) precursor was then patterned onto the PET sheet via laser cutting. Then, the kirigami sheet was mounted onto a stainless steel cylinder with a radius of r 0 and heated in oven for 1 hour to form a kirigami cylindrical shell with a single principal curvature of κ 0 = 1/r 0 . This cylindrical curvature ... 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.
