Mechanical Performance of a Ring‐Arc Auxetic Honeycomb Structure with Double‐Plateau Stress Response

Ring–Arc Honeycomb Metamaterial Structures Metamaterial structures have attracted significant attention owing to their superior energy absorption capabilities. The cover image showcases a novel ring–arc honeycomb (RAH) metamaterial structure, characterized by its distinctive double-plateau stress response. In comparison to the conventional re-entrant hexagonal (RE) honeycomb, the RAH structure exhibits a 282% enhancement in plateau stress and a 191% improvement in specific energy absorption, thereby demonstrating markedly improved energy dissipation capacity.
