In　the　present　work,　a　novel　entangled　metallic　wire　material　(EMWM)　with　good　mechanical　properties　and　electrical　conductivity　was　developed　by　using　beryllium　bronze　alloy　wire　as　raw　material.　A　series　of　thermal-mechanical-electrical　coupling　tests　were　carried　out　to　investigate　the　mechanical　properties　(average　stiffness,　loss　factor)　and　electrical　conductivity　of　beryllium　bronze　alloy　entangled　metallic　wire　material　(QBe2-EMWM)　and　austenitic　stainless　steel　entangled　metallic　wire　material　(304-EMWM).　The　effect　of　the　density　and　ambient　temperature　on　mechanical　performances　and　resistance　properties　of　EMWM　were　analyzed　in　detail.　It　is　found　that　the　mechanical　properties　of　QBe2-EMWM　are　similar　to　those　of　austenitic　stainless　steel　entangled　metallic　wire　material　(304-EMWM).　The　electrical　resistance　of　EMWM　decreases　with　the　increase　of　density.　Moreover,　the　electrical　resistance　of　QBe2-EMWM　is　significantly　lower　than　304-EMWM　and　is　only　5　%　of　304-EMWM.　In　the　aspect　of　theoretical　modeling,　based　on　a　cube　unit-cell　approach,　a　simplified　electrical　resistor　network　was　derived　from　modeling　low-frequency　current　flow　through　the　EMWM.　Considering　the　influence　of　ambient　temperature,　the　simplified　resistor　network　model　was　modified　by　referring　to　the　temperature　term　of　the　Johnson-Cook　model,　and　then　the　conductivity　model　considering　temperature　effect　for　EMWM　was　established.　The　accuracy　of　the　theoretical　electrical　model　of　EMWM　was　verified　by　comparing　the　calculated　results　with　the　experimental　data.　The　results　show　that　the　proposed　model　can　adequately　predict　the　electrical　conductivity　characteristics　of　EMWM　under　different　temperatures.　©　2024
