The structure consists of panel parts and pillar parts. However, the previous manufacturing method is to make them separately and join them by welding. If this can build a structure from a single panel, the number of processes lots will be greatly reduced，and the manufacturing cost will be significantly reduced. To achieve this, it is necessary to bend the panel. The conventional method is a method that reduces the thickness of the folded line, which leads to a decrease in strength. Whether the plate can be bent without lowering the thickness by the origami method developed so far will be studied.
ABE et al. (Wed,) studied this question.
