A Study on Axial Compression of Aluminium Can with Origami Structure

Abstract

In recent years, ecology, sustainable, ethical, etc. have been paid attentions. From this aspect, the existence of foldable aluminum beer cans is expected, however it has not been realized yet so far. Here, it is conceivable to use folding characteristics of origami structures such as a reversed spiral structure. A diamond-cut can with the Yoshimura pattern is similar to this structure. In the case of aluminum, making the folding lines deeper affects the durability. And so, the folding lines showing the Yoshimura pattern is very shallow and cannot be folded as it is. To fold actually, the lines of diamond cut should be thinned with nails etc. and folded. First, how much load is required to crush the current diamond cut can in the axial direction is confirmed together with the usual can by both of experiments and FEM simulations.
