A snapping mechanical metamaterial is designed, which exhibits a sequential snap-through behavior under tension. The tensile response of this mechanical metamaterial can be altered by tuning the architecture of the snapping segments to achieve a range of nonlinear mechanical responses, including monotonic, S-shaped, plateau, and non-monotonic snap-through behavior.
设计了一种能产生连续跃变的折曲机械超材料，其在拉伸下表现出顺序跃变行为。通过调整折曲段的结构，可以改变这种机械超材料的拉伸响应，实现一系列非线性机械响应，包括单调、S 形、平台和非单调跃变行为。
