Overview

Randomized trial demonstrates tunable mechanical performance in metamaterials, indicating advancements for adaptive structures.

Key Points

  • This research aims to develop a 3D metamaterial with tunable mechanical properties under multi-axial loading conditions.
  • Proposed a local stiffening-sensitivity mechanism with selective stiffening points.
  • Utilized finite element analysis paired with a convolutional neural network for performance evaluation.
  • Employed a genetic algorithm for the sequential inverse design of mechanical behavior.
  • Achieved a 0.9 times increase in uniaxial modulus for each additional stiffening point applied.
  • Tuned anisotropy degree ranged from 1 to 35.5.
  • Provided an effective method for adjusting multiaxial mechanical behaviors.
