标准摘要
[中文适用范围]： 本文件规定了在没有显着摩擦影响的纯拉伸成型中测定厚度小于3mm的金属板双轴应力-应变曲线的方法。 与拉伸试验结果相比，可以获得更高的应变值。 注：在本文件中，术语“双轴应力-应变曲线”用于简化。 原则上，在试验中确定“双轴真应力-真应变曲线”。 [外文原描述]： 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.
