Kirigami is a traditional Japanese technique for deforming a two-dimensional incised sheet to form a three-dimensional structure. In this study, this process is reproduced with non-linear finite element analysis, in which (1) a tensil force is applied to the initial incised sheet, (2) the sheet is streched rotating in the out-of-plane direction, (3) the 3D structure is formed. After fixing the final 3D form, its basic mechanical properties are evaluated by linear finite element analysis. This process was repeated by changing the length and position of the incisions to create a response surface. The design parameters (i.e. number and length of incisions) that satisfy the desired mechanical properties are determined with sequential quadratic programming.
