Adjustable Ultra‐Light Mechanical Negative Poisson's Ratio Metamaterials with Multi‐Level Dynamic Crushing Effects (Small 43/2024)

Mechanical Metamaterials In article number 2403082, Xin Wang, Zhen Li, Pengfei Wang, and co-workers designed mechanical metamaterials with multi-level dynamic crushing effects (MM-MLs) through coordinate transformation and mirror arrays. MM-MLs exhibit significant parameter controllability and are capable of achieving various platform stress regions, ranges of Poisson's ratios, and energy absorption requirements, tailored to the specific application scenario. The proposed design scheme can offer insights into adaptive crushing protection requirements.
