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