Description

Multifunctional and multiphysics cellular solids are introduced in this paper as load-bearing structural components. Cellular solids offer a robust low-mass alternative for applications requiring lightweight and stiff components. The unique properties of cellular solids are achieved through cell geometry, connectivity, relative density, and properties of constituent materials. Inspired by biological systems, smart cellular solids can integrate low-mass, sensing/actuating, and self-healing properties into structural components. Discrete fabrication, by integrating patches of smart/active materials onto cellular solids, and continuous fabrication, using additive manufacturing, are two fabrication techniques for the manufacturing of multifunctional cellular solids. We propose a multiscale methodology for the analysis and design of smart cellular structures on the basis of homogenization, structural hierarchy, multiphysics simulation, and multi-objective optimization. It is shown that relative density, cell microarchitechture, cell topology, and volume fraction play a considerable role on the characteristics of multifunctional materials. At last, the potential application of smart cellular solids in civil and building construction industry are reviewed. The paper sheds lights on the emergence of multifunctional and multiphysics materials in industrial sectors and introduces the effect of tailoring the architecture of smart cellular solids in multiple scales on tuning and optimizing the structural functionality.
