This is a video by Ahmad Rafsanjani showing buckling-Induced Kirigami Physical Review. Kirigami is a variation of origami that includes cutting of the paper, rather than solely folding the paper as is the case with origami, but typically does not use glue.Typically, kirigami starts with a folded base, which is then unfolded; cuts are then opened and flattened to make the finished kirigami.

Combined analytical, experimental and numerical results indicate that under uniaxial tension the ligaments buckle out of plane, inducing the formation of 3D patterns whose morphology is controlled by the load direction. By largely stretching the buckled perforated sheets, plastic strains develop in the ligaments. 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. 2b1af7f3a8
