Determination　of　tensile　properties　is　essential　for　the　design　and　strength　assessment　of　structures.　In　this　study,　a　modified　small　punch　test　(SPT),　known　as　the　single-stress　small　punch　test　(SS-SPT),　was　proposed　to　investigate　the　tensile　properties　of　five　ductile　homogeneous　materials,　namely　P91,　Q245R,　316SS,　1045　steel,　and　2024Al.　The　SS-SPT　specimen　was　subjected　to　a　single　stress　state　when　subjected　to　a　punch　force,　similar　to　that　of　a　uniaxial　tensile　test　(UTT)　specimen.　Additionally,　UTT　and　standard　SPT　were　carried　out　to　investigate　the　tensile　properties　of　these　materials.　The　thickness　of　failed　standard　SPT　and　SS-SPT　specimens　was　measured　using　a　scanning　electron　microscope　(SEM)　and　the　equivalent　fracture　strain　was　calculated.　Correlation　relationships　between　each　type　of　SPT　and　UTT　results　were　established.　Experimental　results　indicated　that　both　the　SS-SPT　and　standard　SPT　demonstrated　comparable　accuracy　in　determining　yield　stress,　ultimate　tensile　stress,　and　tensile　elongation.　However,　the　SS-SPT　exhibited　greater　accuracy　than　the　standard　SPT　in　determining　fracture　strain　due　to　direct　measurement　of　the　thinnest　thickness　from　the　fracture　in　failed　SS-SPT　specimens.　©　2025
