Energy absorption of re‐entrant auxetic structures: a parametric study

The present research is focusing on the better understanding of the behaviour of the re‐entrant auxetic structures subjected to impact loads. Various results like the energy absorption capacity, impact force and force‐displacement curves are predicted by performing numerical simulations in ABAQUS. Furthermore, some comparative studies have been performed on different parameters associated with the geometry and the impactor mass to gain a better understanding of re‐entrant auxetic structures on its performance under the impact, mainly focusing on energy absorption characteristics.
