Web(PET) sheet with an average thickness of 0.127 mm. A 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 WebJan 26, 2024 · Kirigami, a traditional paper cutting art, offers a promising strategy for 2D-to-3D shape morphing through cut-guided deformation. Here, authors report a simple …

WebDec 12, 2024 · More specifically, they found that by carefully choosing the thickness of the sheets and the width of the hinges associated with each hierarchical level, the stress–strain response of the surface can be effectively programmed and a variety of different buckling-induced 3D deformation patterns be triggered. WebFeb 24, 2024 · This gives rise to the formation of kirigami sheets comprising periodic distribution of cuts and permanent folds. As such, the proposed buckling-induced pop-up strategy points to a simple route for manufacturing complex morphable structures out of flat perforated sheets. ...

WebApr 13, 2024 · The introduction of patterns such as serpentine [105] or kirigami [106] patterns can relieve stress and strain pressure induced by the tough conductive dopant. Son et al. demonstrated that an electronically inactive self-healing polymer with embedded AgNWs can achieve favorable electrical properties and excellent self-healing [24] . 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 … WebThe latter example can be advantageous because the stretch-induced deformation is uniformly distributed via facet bending rather than concentrated near the hinges, offering a potentially more resilient mechanical performance. ... Kirigami sheets can be developed into morphing surfaces by leveraging the programmable deformation kinematics ... the singularity by ray kurzweil
