Shear Punch

A shear punch test is a very useful small specimen test method for evaluating the mechanical properties of in-service components, in view of the requirements of small size sample material. Typically disks of nominal size 10 mm diameter, having a thickness of 0.5 mm or less is used to extract the tensile properties through measurement of load-displacement responses. This paper presents the results of shear punch tests on pressure vessel steels and its correlation with yield stress and ultimate tensile stress obtained using ASTM standard specimens. Small punch test is similar to shear punch test, except that the indenter is spherical in shape, and as a consequence the material under the punch will be subjected to biaxial state of stress. The tensile response of materials derived by small punch test is correlated with standard tensile tests.

By monitoring the irradiation-induced embrittlement of materials, the Pressure Vessel Surveillance Program (PVSP) contributes to the RPV integrity and lifetime assessments. This program is implemented on each PWR Unit in France; it is mainly based on Charpy tests, which are widely used in the nuclear industry to characterize the mechanical properties of the materials. Moreover, toughness tests are also carried out to check the conservatism of the PVSP methodology. This paper first describes the procedure followed for the Pressure Vessel Surveillance Program. It presents the irradiation capsules: the samples materials (low alloy Mn, Ni, Mo vessel steel including base metals, heat affected zones, welds and a reference material) and the mechanical tests performed. Then it draws up a synthesis of the analysis of about 180 capsules removed from the reactors at fluence levels up to 7.1019 n/cm2 (E > 1 MeV). This database gathers the results of more than 10,000 Charpy tests and 250 toughness tests. The experimental results confirm the conservatism of the Code-based methodology applied to the toughness assessment.

Spectrum Effect

The large scatter emerging from KIc measurements for heavy walled pressure vessel steels is examined in view of new data for A533B. Extensive plastic flow data at −220 deg F and 80 deg F has revealed a marked, and apparently harmonic, flow strength variation repeated at strain rate intervals in ratio of about 20. The tension skewed path over these ridges is related to the KIc behavior, for which a corresponding variational pattern with loading rate K˙ is observed. The variational pattern, or rate spectrum effect, is large compared to the average speed sensitivity of KIc, suggesting that transition temperatures values could be measured at a more moderate, though rapid, loading rate to avoid the inertial ringing effects of impact.
