Metallic materials - Sheet and strip - Determination of biaxial stress-strain curve by means of bulge test with optical measuring systems (ISO 16808:2014)
This International Standard 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.
