Recent Progress in Active Mechanical Metamaterials and Construction Principles

Advanced Science, Journal Year: 2021, Volume and Issue: 9(1)

Published: Oct. 29, 2021

Abstract Active mechanical metamaterials (AMMs) (or smart metamaterials) that combine the configurations of and active control stimuli‐responsive materials have been widely investigated in recent decades. The elaborate artificial microstructures stimulus response characteristics both contribute to AMMs, making them achieve excellent properties beyond conventional metamaterials. micro macro structures AMMs are designed based on structural construction principles such as, phase transition, strain mismatch, instability. Considering controllability efficiency materials, physical fields temperature, chemicals, light, electric current, magnetic field, pressure adopted as external stimuli practice. In this paper, frontier works latest progress from aspects mechanics reviewed. functions engineering applications also discussed. Finally, existing issues future perspectives field briefly described. This review is expected provide basis inspiration for follow‐up research AMMs.

Mechanostructures: Rational mechanical design, fabrication, performance evaluation, and industrial application of advanced structures

Progress in Materials Science, Journal Year: 2022, Volume and Issue: 131, P. 101021 - 101021

Published: Sept. 21, 2022

The rapid progress of advanced manufacturing, multidisciplinary integration and artificial intelligence has ushered in a new era technological development the design lightweight, well-integrated, multifunctional, intelligent, flexible biomimetic materials structures. traditional approach structural research poses several intrinsic limitations on practical performance devices instruments harsh industrial environments, due to factors such as disconnection between low efficiency manufacture complex structures, reduced actual mechanical integrity reliability manufactured structures compared theoretical values obtained from design, insufficient level multifunctional integration, excessive economic cost. In addition, incorporated equipment often need withstand extreme service it is increasingly important further integrate manufacture, function, evaluation application provide technical bases for optimizing their fabrication. view above, authors propose paradigm "mechanostructures," which aims achieve target responses environments by integrating manufacturing evaluation. By designing novel based desired static dynamic considering behavior throughout whole deformation process, field "mechanostructures" pursues an application-oriented approach. As typical example mechanostructures, lightweight lattice with high stiffness, strength, impact resistance, energy absorption capacity, shock wave attenuation noise reduction show great potential applications aerospace, transportation, defense, biomedical, energy, machinery, other fields. this respect, metastructures inspired polycrystalline microstructures presented, starting discussion properties conflicts, demonstrating scientific merits innovative manipulation properties, elaboration underlying physical mechanisms.

Elastic mechanical property hybridization of configuration-varying TPMS with geometric continuity

Materials & Design, Journal Year: 2022, Volume and Issue: 221, P. 110995 - 110995

Published: July 30, 2022

Hybrid design is an effective approach to construct functional mechanical metamaterials. In this study, a periodic hybrid method for the TPMS (triply minimal surface) structures proposed, maintaining original surface connectivity and structural strength. It implemented by combination of implicit function Ψ(x,y,z) transition ηx,y,z governing equation. Furthermore, three classical TPMS, i.e., P (Schwarz Primitive), IWP (Schoen I-WP) FRD F-RD), are represented study elastic properties hybridizations using FE (Finite Element) computational experiments. Through RVE-based (Representative Volume homogenization method, it demonstrated how hybridization expands designable range modulus. addition, hybridizations, such as axial modulus, diagonal modulus anisotropy, etc., can be quantificationally tailored turning formal parameters TPMS.
