Metallic materials - Sheet and strip - Determination of biaxial stress-strain curve by means of bulge test with optical measuring systems (ISO 16808:2022)
This document specifies a method for determination of the biaxial stress-strain curve of metallic
sheets having a thickness below 3 mm in pure stretch forming without significant friction influence. In
comparison with tensile test results, higher strain values can be achieved.
NOTE In this document, the term "biaxial stress-strain curve" is used for simplification. In principle, in the
test the "biaxial true stress-true strain curve" is determined
