Anomalous size effects with fixed criticality in bistable flexible mechanical metamaterials
Zehuan Tang, Tingfeng Ma, Boyue Su +3
When the structure deformation is dominated by the low-energy deformation mode, the structure hardens with the increase in the size (number of units) at small sizes. This anomalous…
