Özet

The purpose of this study is to examine the energy absorption characteristics of two different auxetic honeycombs that have negative Poisson's ratio (NPR) subjected to an axial quasi-static load. The total mass and volume are kept nearly equal. As the load-extension graphs are examined, it is observed a smooth transition of the peak forces during the crush for the second one which has more strut. On the other hand, first one has better energy absorption capability.
