Abstract:

Metamaterials or Architected Materials are structural configurations of repeating patterns that have material properties not found in natural materials.  The shape, the geometry, the topology, the size, and the combination of conventional material give metamaterials their tunable properties.  Metamaterials can be designed to have negative Poisson’s ratio, that are great for ballistic protection and radar avoidance, or zero coefficient of thermal expansion, that are great for stress reduction on environments with high thermal gradients. Other applications of tunable metamaterials can be found in optical filters, high-frequency battlefield communication devices, medical devices, sensors, energy absorption devices, radomes with negative permittivity and permeability characteristics, etc.

The advances in additive manufacturing, lattice generation tools and the multi-material metallic printers enable the manufacturing of metamaterials. The challenge is to conceive, design and validate metamaterial concepts. In this presentation the recent progress in lattice generation tools coupled with optimization techniques will be outlined.  A practical metamaterial discovery process that generates a near zero coefficient of thermal expansion material will be demonstrated using CREO.
