From: Mechanical metamaterials made of freestanding quasi-BCC nanolattices of gold and copper with ultra-high energy absorption capacity

Fig. 3

a SEM snapshots of the deformation process of the sample Au-69. b Stress–strain curves of the gold and copper quasi-BCC nanolattices of the samples Au-117, Au-86, Au-69, Au-34, Cu-34, respectively. c Compressive stiffness versus relative density and d Compressive strength versus relative density of gold and copper quasi-BCC nanolattices. Scale bar 2 μm. The error bars denote the standard deviations of the mean values measured from at least three micropillars. Source data are provided as a Source Data file.
