Twin mechanical metamaterials
WebMechanical metamaterials can be classified into two cate-gories: mono-stable and multi-stable. The mono-stable NS metamaterial can recover to the initial shape without external force after unloading, while the multi-stable NS metamaterial would remain deformed state after unloading. Their mechanical response under compression is described by the WebJan 5, 2024 · Abstract and Figures.
