Design and additive manufacturing of 3D auxetic octahedron structure for enhanced specific energy absorption

|
By Jeongho Yang, Seung Chul Han, Jeonghyeon Bae, Joontae Ji, Cheolwoo Ha
| Nature Verified
Abstract The 3D auxetic structures are increasingly recognized for their potential to enhance specific energy absorption (SEA). Conventional auxetic structures are typically limited to 2D or 2.5D configurations and inherent gaps are generated between the unit cells due to the length of the connecting nodes. There is a need for research focused on improving the specific energy absorption through effective 3D deformation behaviors.
