Abstract: This talk is about the applications of origami structures as energy absorption devices. For example, I will introduce a novel thin-walled energy absorptiondevice known as the origami crash box whose surface is prefolded according to a developable origami pattern. The prefoldedsurface serves both as a type of geometric imperfection to lower the initial bucklingforce and as a mode inducer to trigger a collapse mode that is more efficient in terms ofenergy absorption. It has been found out from quasi-static numerical simulation that a newcollapse mode referred to as the completed diamond mode, which features doubled travelingplastic hinge lines compared with those in conventional square tubes, can be triggered,leading to higher energy absorption and lower peak force than those of conventional onesof identical weight.
