- Abstract
Inspired by origami shape, two origami tubes are obtained through the arrangement of single-origami-cell structures (SOSs). Under quasi-static compression load, the specific energy absorption (SEA) value of same direction origami tube (SOT) is 13.46% higher than that of reverse origami tube (ROT). ROT shows the deformation mode of compression rotation, and SOT is layer by layer crushing. Various two-, three-, and four-layer origami structures are proposed through the combination of origami tubes and connecting plates, and their energy absorption efficiency is significantly higher than that of origami tubes. These origami structures exhibit stable deformation modes, mainly axial compression, torsion, and mixed deformation modes. The deformation mode of origami structures with four ROTs (4R) is similar to Fried Dough Twists. Regarding two-layer structures, origami structures consisting of reverse SOTs (RSOTs) and SOTs have significantly higher SEA values than those composed of ROTs and SOTs as well as ROTs and RSOTs. In addition, the compression performance of two-layer origami structures is significantly better than that of three- and four-layer origami structures. The SEA value of two-layer origami structure with two RSOTs and two SOTs (2RS2S) is higher than that of three-layer origami structure with four A cells (4A) and four-layer origami structure with one C cell and three D cells (1C3D) 68.05% and 64.48%, respectively. In summary, the origami structures show excellent mechanical properties and have broad application potential as energy absorbing structures. [ABSTRACT FROM AUTHOR]
