Entangled　metallic　wire　material　(EMWM)　is　a　kind　of　porous　damping　material.　To　promote　the　engineering　application　of　EMWM,　it　is　necessary　to　establish　the　constitutive　model　of　EMWM　to　estimate　its　mechanical　properties.　In　this　paper,　a　series　of　quasi-static　compression　experiments　for　plate-like　EMWM　specimens　made　of　austenitic　stainless　steel　wire　(06Cr19Ni10)　with　different　densities　were　carried　out　in　the　temperature　range　of　20-500　degrees　C.　It　was　found　that　the　stiffness　of　the　plate-like　EMWM　would　increase　with　the　increases　in　the　ambient　temperature.　The　non-linear　characteristics　of　the　force-displacement　curve　of　the　plate-like　EMWM　would　be　weakened.　Taking　the　spatial　structural　characteristics　of　the　plate-like　EMWM　and　the　influence　of　the　thermal　expansion　of　the　structure　into　account,　a　new　constitutive　model　for　plate-like　EMWM　was　presented　by　the　combination　of　the　Johnson-Cook　model　and　the　Sherwood-Frost　constitutive　framework　model.　The　accuracy　of　the　model　was　verified　by　the　experimental　data　under　different　temperatures.　The　results　show　that　the　calculated　results　of　the　model　are　consistent　with　the　experimental　results.　This　model　can　provide　an　effective　theoretical　basis　for　predicting　the　mechanical　properties　of　plate-like　EMWM　and　guiding　its　design.
