102 台形平面化した円筒の圧潰特性に関する研究  [in Japanese] A Study on Crushing Characteristic of Trapezoidally Planed Cylinders  [in Japanese]

This paper has tried to develop crushable beverage cans for recycling. Trapezoidally planed cylinders based on origami model are studied by the experiment of PP-sheet and by the numerical simulation of implicit finite element analysis. It is found that the axial crushing load can be reduced by adjusting the trapezoidal parameters such as the number and sizes of trapezoid and the spiral angle.
