Websmaller scale test procedures. One particular test methodology is the small punch (SP) test, an experimental approach derived in the 1980s to assess in-service degradation of nuclear reactor com-ponents exposed to irradiation damage [1] and to provide an indi-cation of the residual lifetime of the material for further safe operation. WebIt was found that the 2024-T3 and 7075-T651 aluminum alloys were shown to have the highest maximum small punch force before failure. The relationship between the SPT parameters and the yield strength, tensile strength, elastic modulus, and hardness is shown to be linear. The empirical equation developed here is suitable for aluminum alloys.
WebDec 20, 2024 · In a small punch creep (SPC) test, a miniature disc specimen with typical dimensions of 8–9.5 mm in diameter and 500 μm in thickness is subjected to a constant load that is applied to the material through a punch indenter. As the load is applied to the disc, the material undergoes a biaxial form of deformation prior to the onset of final rupture.
