Abstract: In order to produce the origami-based foldable structures, designers have to determine the industrial material type, the geometry of structures and dimensions etc. These structures may be deformed in proportion to the load at the first step, and show the property of spring. Next step, the deformation will become non-linear conduct. However, deformation mechanism in these structures cannot be estimated yet well. So, appropriate design for shock absorbers cannot be done easily. In this paper, by experiments and FEM analysis, we present the theory of deformation mechanism on origami based foldable structures, which are made of resin or metal, have many types of dimensions and geometry. This theory shows not only the relationship between dimensions of structures and spring constant but also the relationship between material constant and the load to fold structures.
