The　modified　Gurson-Tvergaard-Needleman　(GTN)　model　is　employed　to　predict　the　ductile　fracture　of　7A62　high-strength　aluminum　alloy　under　a　wide　range　of　stress　states.　Mechanical　tests　were　conducted　on　specimens　with　different　stress　states　within　the　range　of　−0.33　to　1.35　stress　triaxiality,　including　tension,　notched　tension,　compression,　and　shear.　The　results　indicate　that　at　high　stress　triaxialities　(0.8　∼　1.35),　the　fracture　mechanism　is　intergranular　ductile　fracture.　Under　moderate　stress　triaxialities　(0.33　∼　0.8),　the　fracture　mechanism　involves　a　combination　of　intergranular　ductile　fracture,　void　growth,　and　shear　fracture.　At　low　and　negative　stress　triaxialities　(−0.33　∼　0.33),　plastic　instability　occurs　due　to　uneven　stress　distribution,　leading　to　shear　fracture.　Fractography　analysis　reveals　that　the　fractures　occurring　under　tensile　stress　are　associated　with　enriched　Mn　particles　of　approximately　200　nm.　The　modified　GTN　model　accurately　predicts　the　load-displacement　response,　and　the　fracture　paths　under　various　stress　states　exhibit　good　consistency　with　experimental　results.　This　study　provides　reference　for　failure　prediction　in　the　engineering　application　of　high-strength　aluminum　alloys.　©　2024　IOP　Publishing　Ltd.
