Abstract
Formally we have discussed the collapse easiness of two pairing structures: Nojima polyhedron (NP) and Tachi-Miura polyhedron (TMP), for the applicability of empty beer cans made of the aluminum material. This paper is focused on the investigation of the absorbing energy performance and the crushing modes. We consider the application of these pairing origami structures to expect to be used as the collision energy absorber of vehicles with the steel material. The impact analyses are performed by using dynamic explicit finite element program LS-DYNA. Moreover, we compare the collapse characteristics of the investigated structures with the conventional rectangular cross section structure and reversed spiral cylindrical origami structure (RSC).
