Overview

Finite element analysis reveals directional auxeticity in mechanical metamaterials, suggesting optimal designs for biomedical scaffolds.

Key Points

  • Mechanical metamaterials exhibit distinct auxetic behaviors driven by geometry and material properties.
  • Analysis achieved extreme negative Poisson’s ratios in specified lattices, enhancing material understanding.
  • Finite element analysis and sensitivity testing ensured robust numerical reliability across various geometries.
  • Insights guide the selection of metamaterial topologies for applications in biomedical scaffolds and safety gear.
