Oct 01, 2016 V. Auxetic Effect As listed in Table 1, the dynamic crushing strength, which is of great importance to energy absorption, is higher for re-entrant honeycomb than for conventional hexagon topology. The underlying physical explanation is that with the same cell wall aspect ratio, the re-entrant honeycomb has higher relative density.
