折畳缶の検討

抄録

In recent years, ecology, sustainable, ethical, etc. have been paid attentions. From this aspect, the developing 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 origami structure. In the case of aluminum, processing the folding lines deeper affects the durability. And so, the folding lines for 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. First, it is confirmed here how much load is required to crush the current diamond cut can and the usual one in the axial direction by both experiments and FEM simulations.
