Metal　rubber　materials,　formed　by　entangling　single　metal　wires　and　also　known　as　ESW-MR,　have　attracted　widespread　attention　due　to　their　unique　non-linear　load　curves　and　excellent　environmental　adaptability.　The　mechanical　behavior　of　these　materials,　which　are　created　through　the　weaving　or　winding　of　pure　metal　wires,　is　influenced　by　the　structural　characteristics　of　semi-flexible　fiber　cross-linked　fibers.　This　study　delves　deeply　into　the　microstructure　of　ESW-MR,　with　the　aim　of　establishing　a　numerical　model　that　can　accurately　simulate　and　characterize　its　structure.　A　method　based　on　arbitrarily　defined　baselines　parametric　equations　in　the　global　space　was　adopted,　leading　to　the　creation　of　a　parametric　model　for　a　continuously　wound　wire　with　multiple　spiral　mechanisms.　Finite　element　simulations　based　on　explicit　dynamics　were　conducted　using　LS-DYNA　and　could　successfully　simulate　the　cold　stamping　forming　process　of　ESW-MR　blanks.　The　model　was　validated　through　stamping　and　quasi-static　tests,　as　well　as　computed　tomography　(CT)　scan　tests.　The　results　demonstrate　the　model　accuracy　in　describing　the　macroscopic　and　microscopic　characteristics　of　the　material,　showing　excellent　agreement　with　the　actual　material.　Furthermore,　the　study　successfully　extracted　the　micro-topological　features　of　the　material,　providing　additional　quantitative　information　on　the　topological　characteristics　of　ESW-MR.　This　work　offers　a　valuable　tool　for　the　study　and　application　of　ESW-MR　and　presents　a　novel　perspective　for　the　numerical　simulation　of　a　wide　range　of　entangled　materials.　It　paves　the　way　for　gaining　a　deeper　understanding　of　the　microstructure　and　mechanical　behavior　of　such　materials.　©　2023　Elsevier　B.V.
