Resumo
The Small Punch Test (SPT) method is an “almost non-destructive”[1] method by uses
miniaturized samples to obtain mechanical properties of materials. It was development by
nuclear industry to analyses mechanical behavior of irradiated materials principally by small
volume of the samples, which facilitates their storage and handling. Its applications are
spreading across several areas of materials engineering, for use in situations where
conventional methods do not apply. SPT consists of pressing a sphere, with a diameter equal
to 2.5 mm, in a miniaturized sample of circular geometry (diameter d = 8 mm and thickness
about 0.5 mm)[2], which has fixed edges, tested in conventional mechanical testing
machines with the aid of a device developed for their achievement.
In this work, mechanical properties of stainless steel (316 L) were abstained by two
different methods: conventional tensile test and the small punch test (SPT), for comparing
the results and allow the evaluation of the method. The SPT results depends on graph
interpretations and discussions take place at now. Correlations of results guide us in
choosing the most appropriated method for interpreting the force x displacement graph
from SPT.
