Abstract：

Tensile　properties　play　a　critical　role　in　characterizing　the　mechanical　behavior　of　cladding　tubes.　In　this　study,　a　modified　small　punch　test　(SPT)　called　single　stress　small　punch　test　(SS-SPT)　was　proposed　to　investigate　the　axial　tensile　properties　of　cladding　tubes.　Semi-cylindrical　SS-SPT　specimens,　directly　prepared　from　cladding　tubes,　were　subjected　to　a　single　stress　state　under　an　applied　punch　force.　Finite　element　simulation　results　demonstrated　that　determining　both　yield　stress　and　ultimate　tensile　stress　using　the　SS-SPT　was　not　only　feasible　but　also　accurate.　Moreover,　the　axial　tensile　properties　of　a　FeCrAl　cladding　tube　were　investigated　using　the　SS-SPT.　It　was　observed　that　the　determined　axial　yield　stress　and　ultimate　tensile　stress　of　the　FeCrAl　cladding　tube　exhibited　a　reduction　of　7　%,　compared　to　those　obtained　from　axial　uniaxial　tensile　tests.　©　2025　Elsevier　Ltd
