ISO 16808:2014规定了在无明显摩擦影响的纯拉伸成形中,厚度小于3mm的金属板的双轴应力-应变曲线的测定方法。与拉伸试验结果相比,可以获得更高的应变值。
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.
