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.
