Entangled　porous　metallic　pseudo-rubber　(EPMPR)　is　formed　by　interlaced　helical　metal　wires,　and　its　unique　structure　can　convert　mechanical　vibration　energy　into　heat,　providing　significant　damping　effects.　This　study　innovatively　proposes　a　method　for　constructing　the　elastic　hysteresis　curve　of　EDMMR　at　the　physical　level,　and　decomposes　and　extracts　the　hysteresis　curve　using　virtual　manufacturing　technology　(VMT).　Based　on　finite　element　numerical　calculation　nodes,　this　study　constructs　the　stiffness　curve　of　EPMPR＇s　series-parallel　structure,　and　considers　the　contact　behavior　of　EPMPR,　especially　under　high-temperature　conditions,　through　dynamic　evolution　analysis　of　discretized　numerical　models　of　spatial　contact　behavior,　further　studying　its　damping　hysteresis　behavior.　Specifically,　this　study　also　proposes　for　the　first　time　and　comprehensively　analyzes　the　dynamic　and　static　parameters　of　EPMPR　under　different　temperatures　and　loads,　providing　in-depth　insights　into　its　mechanical　behavior　and　energy　dissipation　mechanisms.　Experimental　results　demonstrate　that　under　the　complex　topology　structure　and　thermomechanical　coupling,　the　elastic　hysteresis　curve　of　EPMPR　can　accurately　predict　its　damping　characteristics　under　different　high-temperature　environments,　providing　a　theoretical　foundation　for　EPMPR＇s　application　in　advanced　equipment　and　structural　extreme　environments.　©　2025　Elsevier　Masson　SAS
