Standard tensile test compared to the small punch test of aluminium alloy

Abstract

The paper deals with certain similarities in results of standard tensile testing and small punch tests. The study is conducted using wrought aluminium alloy 2024-T351, which is solution heat treated, stressrelieved stretched and then cold worked. This aerospace alloy has been rarely used in small punch testing, but it is well documented by standard testing techniques. Basic mechanical properties obtained by two distinct methods are compared and main consequences of the empirical estimations from the small punch testing are concluded.
