The bumper beam of a transport vehicle conventionally is commonly made from thin-walled materials with a shallow curved profile, with either opened or closed cross sections. Upon lateral crushing, it fails in a bending collapse mode characteristic of formation of a limited number of plastic hinges along the beam. This paper presents a novel structure known as the origami beam.
