多稳态力学超构材料研究进展
Research progress of multi-stable mechanical metamaterials
摘要
Abstract
Mechanical metamaterials can achieve extraordinary mechanical properties that natural materials do not have through artificially designed microstructures,such as negative Poisson's ratio,negative thermal expansion,multistability,tunable stiffness,etc.Among them,multi-stable mechanical metamaterials have attracted researchers'interest due to their excellent properties such as reusability,energy storage and absorption,rapid deformation and amplification of output force.Multi-stable mechanical metamaterials are usually realized by series and/or parallel connection of bistable structural units.They exhibit multiple stable configurations under external loads and can be switched inversely,which has broad application prospects.This paper reviews the main design strategies and the latest research progress of multi-stable mechanical metamaterials.And then,the concept of bistability,the energy barrier of steady-state conversion and the mechanical response characteristics are further elaborated.The research progress of bistable units and their multi-stable metamaterials is analyzed according to the different research objects.In addition,the prospects of multi-stable mechanical metamaterials for applications in energy absorption,soft driving,mechanical computing and wave control are discussed.Finally,the research on multi-stable mechanical metamaterials is summarized,and the potential challenges and opportunities in the future are prospected.关键词
