A　constitutive　model　is　developed　to　efficiently　capture　the　nonlinear　hysteretic　properties　of　a　new　type　of　high-damping　metal　wire　mesh　(HDMWM).　In　the　HDMWM,　the　metal　wire　mesh　is　woven　with　multi-strand　twisted　wires　in　a　certain　regularity.　In　the　quasi-static　test,　six　batches　of　metal　wire　mesh　(MWM)　and　HDMWM　specimens　with　different　densities　and　varying　number　of　strands　are　prepared　and　their　mechanical　properties　are　characterized　by　secant　stiffness,　energy　consumption　and　loss　factor.　Results　show　that　for　the　same　density,　the　energy　consumption　and　loss　factor　of　HDMWM　specimens　are　higher　than　MWM　specimens　by　10.69　~　22.83%　and　44.19　~　48.44%,　respectively.　Additionally,　HDMWM　is　found　to　have　a　higher　damping　level　than　MWM.　A　constitutive　model　is　proposed　that　comprises　a　cantilever　beam　as　the　force　analysis　element　where　the　change　of　the　arc　angle　of　the　element　mesh　is　similar　to　a　normal　distribution.　The　accuracy　of　the　model　is　verified　by　error　analysis,　which　shows　that　the　relative　percentage　error　between　model　results　and　test　results　is　0.97　~　12.13%.　Therefore,　the　constitutive　model　can　reflect　the　mechanical　properties　of　HDMWM　with　reasonable　accuracy.　©　2023,　ASM　International.
