Overview

This review highlights energy absorption efficiencies in auxetic structures, suggesting additive manufacturing for enhanced mechanical properties.

Key Points

  • Auxetic structures improve energy absorption capacity, reducing peak stress by 20%–40% and enhancing durability.
  • Key performance metrics include superior mechanical properties under quasi-static loading conditions.
  • Optimization methods such as surrogate-assisted machine learning facilitate advanced designs for energy absorption.
  • Integrating specific geometries and materials may support the development of effective auxetic energy absorbers.],
