Extended Data Fig. 8: Multiple impacts.
From: Harnessing plasticity in sequential metamaterials for ideal shock absorption
a,b, Snapshot comparisons at each impact of the sequential metamaterial and the crash can with the same stiffness and strength. Each impact has a speed of 3.2 m s−1 and a weight of 5.5 kg. c,d, The impact speed V versus impact time at each impact of the metamaterial (c) and the crash can (d). e,f, The deceleration (Dec.) versus compressive stroke under six impacts of the metamaterial (e) and the crash can (f).
