摘要

研究了两种负泊松比(NPR)的消声蜂窝在轴向准静态载荷作用下的吸能特性。总质量和体积几乎保持相等。随着加载-扩展图的检查，它被观察到一个平滑过渡的峰值力在挤压期间第二个有更多的支柱。另一方面，前者具有更好的能量吸收能力。

Experimental investigation of auxetic structures subjected to quasi static axial load

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.
