Influence of Unit‐Cell Geometry on 3D‐Printed Chiral‐Inspired Tubular Metamaterials: Auxeticity and Energy Absorption in Athletic Footwear Applications

Lightweight architected metamaterials capable of simultaneously achieving high energy absorption, tailored stiffness, and superior auxetic behavior are increasingly required for advanced engineering applications. However, chiral metamaterials have been studied mainly in planar architectures or relatively simple three‐d...

Soft materials in aerospace: from discrete functional elements to integrated system enablers

Soft materials are attracting increasing attention in aerospace engineering because they provide combinations of compliance, multifunctionality, and environmental adaptability that are difficult to achieve simultaneously with conventional rigid materials. This review summarizes recent progress in the use of elastomers,...
