The　ballistic　impact　of　two　7XXX　aluminum　alloys,　7A52-T6　and　7A62-T6,　as　well　as　their　combination　in　a　7B52　laminate　plate,　was　simulated　and　experimentally　tested.　Three　types　of　projectiles　were　utilized　hard　ogival　nosed,　hard　blunt　nosed,　and　304　steel　core　projectiles　to　investigate　the　ballistic　resistance　and　failure　mechanisms　of　the　aluminum　alloy　targets.　Additionally,　an　existing　modified　Gurson-Tvergaard-Needleman　(GTN)　model　incorporating　shear,　void　growth,　and　spalling　failure　mechanisms,　was　employed　to　simulate　the　ballistic　impact　process,　utilized　to　analyze　energy　dissipation　during　impact.　The　results　reveal　that　the　7A52　alloy　only　experiences　ductile　hole　expansion　failure,　whereas　the　7A62　high-strength　aluminum　alloy　undergoes　spalling　and　fragmentation　subsequent　to　penetration,　leading　to　potential　impact　hazards.　Due　to　its　backing　layer　being　the　highly　ductile　7A52　alloy,　the　laminate　plate　will　not　produce　fragments　after　penetration.　The　improved　GTN　model　provided　better　predictions　of　the　impact　failure　modes　of　the　aluminum　alloys.　Concerning　impact　performance,　when　subjected　to　hard　ogival　projectiles,　the　laminate　alloy　did　not　enhance　material　impact　resistance.　However,　when　impacted　by　blunt-nosed　projectiles,　the　laminate　alloy　exhibited　a　27　%　improvement　over　the　7A52　plate　and　an　11.9　%　increase　over　the　7A62　plate.　Furthermore,　when　impacted　by　304　steel　core　ogival　projectiles,　the　laminate　alloy　demonstrated　over　a　41.3　%　improvement　compared　to　the　7A52　plate　and　over　a　15.5　%　increase　compared　to　the　7A62　plate.　The　laminate　plate＇s　high　ballistic　performance　was　attributed　to　the　increased　plastic　deformation　energy　after　spalling　failure,　while　ensuring　high　energy　absorption　during　ductile　hole　expansion　penetration.
