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 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.
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. 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. ... This is because the S-shaped pores introduce a soft mode of ...
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 ...
