In　this　paper,　the　dynamic　compressive　mechanical　properties　of　entangled　metallic　wire　material　(EMWM)　under　low-velocity　impact　were　investigated　and　the　constitutive　model　for　EMWM　under　low-velocity　impact　was　established.　The　research　in　this　paper　is　based　on　a　series　of　drop-hammer　tests.　The　results　show　that　the　energy　absorption　rate　of　EMWM　is　in　the　range　from　50%　to　85%.　Moreover,　the　EMWM　with　a　higher　relative　density　would　not　plastically　deform　macroscopically　and　has　excellent　characteristics　of　repetitive　energy　absorption.　With　the　increase　in　relative　density,　the　maximum　deformation　of　EMWM　decreases　gradually,　and　the　impact　force　of　EMWM　increases　gradually.　With　the　increase　in　impact-velocity,　the　phenomenon　of　stiffness　softening　before　reaching　the　maximum　deformation　of　EMWM　becomes　more　significant.　A　constitutive　model　for　EMWM　based　on　the　Sherwood-Frost　model　was　established　to　predict　the　dynamic　compressive　mechanical　properties　of　EMWM.　The　accuracy　of　the　model　was　verified　by　comparing　the　calculated　results　with　the　experimental　data　of　the　EMWM　with　different　relative　densities　under　different　impact-velocities.　The　comparison　results　show　that　the　established　model　can　properly　predict　the　dynamic　compressive　mechanical　characteristics　of　EMWM　under　low-velocity　impact　loading.
