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.
