Experimental investigation of auxetic structures subjected to quasi static axial load

摘要

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.
