This　work　presents　the　experimental　characterization　and　improved　model　of　multi-strand　entangled　metallic　wire　materials　(MS-EMWMs).　MS-EMWM　is　a　novel　damping　material　made　of　several　strands　of　entangled　wires　using　a　modified　manufacturing　process.　Six　batches　of　specimens　were　fabricated　and　tested　under　quasi-static　loading.　Secant　stiffness　and　loss　factor　were　calculated　to　indicate　the　mechanical　properties.　The　results　showed　that　MS-EMWM　has　the　characteristics　of　high　damping　energy　dissipation　compared　to　EMWM.　A　micro-multi-strand　spiral　spring　model　was　proposed　to　predict　the　mechanical　properties　of　MS-EMWM.　The　probability　distribution　of　micro-spring　pairs　between　wires　was　used　to　characterize　the　random　combination　of　materials.　According　to　the　results,　the　improved　model　can　effectively　reflect　the　mechanical　behavior　of　MS-EMWM.　The　mechanical　properties　of　MS-EMWM　were　predicted　by　the　coefficient　matrix　obtained　by　particle　swarm　optimization.　Through　the　prediction　and　test　results,　the　predicted　results　are　acceptable.　©　The　Author(s)　2023.
