Extreme Specific Stiffness Through Interactive Cellular Networks in Bi‐Level Micro‐Topology Architected Metamaterials
Architected lattice materials, realized through artificial micro‐structuring, have drawn tremendous attention lately due to their enhanced mechanical performances in multifunctional applications. However, the research area on the design of artificial microstructures for the modulation of mechanical properties is increasingly becoming saturated due to extensive investigations considering different possibilities of lattice geometry and beam‐like network design. Thus, there exists a strong rationale for innovative design at a more elementary level. It can enhance and grow the microstructural space laterally for exploiting the potential of geometries and patterns in multiple length scales, and the mutual interactions thereof. A bi‐level design is proposed, where besides having the architected cellular networks at an upper scale, the constituting beam‐like members at a lower scale are further topology‐engineered for most optimum material utilization. The coupled interaction of beam‐level and lattice‐level architectures can enhance the specific elastic properties to an extreme extent (up to ≈25 and 20 times, depending on normal and shear modes, respectively), leading to ultra‐lightweight multifunctional materials for critical applications under static and dynamic environments.
