通过利用弹穿不稳定性，D. Pasini 及其同事设计了一种耐损伤机械超材料，该超材料在张力作用下会连续折断，从而可承受高达 150% 的巨大变形。在第 5931 页，他们描述了如何通过调整其晶胞的架构来稳健地编程超材料的非线性机械响应。
By exploiting snap-through instabilities, D. Pasini and co-workers design a damage-tolerant mechanical metamaterial that snaps sequentially under tension, thereby accommodating a very large deformation up to 150%. On page 5931, they describe how the nonlinear mechanical response of the metamaterial can be robustly programmed by tuning the architecture of its unit cell.
