Special Issue Information

Dear Colleagues,

The design of mechanical metamaterials often makes use of cellular and lattice patterns. The right tuning of these architectures via geometric and dimensional parameter adjustment allows the designer to produce topologies with tailored mechanical properties. Hence, architected mechanical metamaterials appear as a promising option for various applications, e.g., lightweight structures, energy storage, biomedical, and vibration and noise control, among others.

Mechanical metamaterials, also known as architected cellular materials, are not new. They can be found in nature as integral parts of honeycombs, wood, and bone. However, the advent of additive manufacturing technologies has indeed enabled growth in the design and understanding of such porous media. This is attributed to the design freedom enabled by additive fabrication processes. Additive manufacturing facilitates the fabrication of complex geometries which are often demanded by mechanical metamaterials. A wide range of geometrical and structural elements could be used to build up cellular structures, prompting them to be additively manufactured. This Special Issue aims to collect recent developments in the areas related to mechanical metamaterials fabricated with additive manufacturing.

Submissions are welcome that cover, but are not limited to, the aspects of:

  • Design of mechanical metamaterials.
  • Design for additive manufacturing.
  • Mechanical properties of cellular and lattice materials.
  • Additive manufacturing of architected materials.
  • Experimental characterization of the mechanical properties of cellular materials.
  • Computational approaches to characterize structure–property relation.
  • Other cutting-edge research on understanding the structure/manufacturing–property relation of this architected media.
  • Other applications of metamaterials, e.g., vibration and damping control and noise attenuation.

In order to meet the higher requirements of energy-absorbing structures in the lightweight automobile design, the mechanical design and impact energy absorption of porous TPMS structures are studied. Eight kinds of porous TPMS structure elements, Gyroid, Diamond, I-WP, Neovius, Primitive, Fischer-Koch S, F-RD, and PMY, are designed based on Matlab, and the porous structure samples composed of eight elements are printed and molded using SLM. The deformation mechanism, mechanical response, and energy absorption characteristics of different porous TPMS structures are investigated. Gyroid and Primitive elements are selected to fill the internal structure of the energy-absorbing automobile boxes. Traditional thin-walled energy-absorbing boxes served as a control group and were subjected to low-speed impact testing. The results show that the peak load of the energy-absorbing box filled with TPMS porous structures is almost equal to the average load under a 4.4 m/s impact, and the SEA of the energy-absorbing box filled with TPMS porous structures is higher than the traditional thin-walled energy-absorbing box. The problems of excessive peak load and inconsistent load fluctuation of traditional thin-walled energy-absorbing structures are effectively solved by porous TPMS structures with the assurance that the lightweight and energy-absorbing requirements are still met.
