In this contribution, the behaviour of Ti6Al4V auxetic structures and bulk cylinders under impact loading is studied experimentally and numerically
and results are compared among them. Using a destructive test approach (DT), these structures are impacted by a loader launched at a given height. The response of the structure on different impactors with different impact energy is monitored by a high-speed camera and radial displacement history is measured by a high speed vibrometer. The corresponding energy absorption in elastoplastic regime is analysed. Besides, this experiment will allow to access the dynamic deformation
