标准摘要
[中文适用范围]： 本文件规定了使用由金属板材样品制成的十字形测试件测量受到双轴拉伸的金属板材的应力-应变曲线的方法。 适用的板材厚度为十字形试件臂宽的 0.1 毫米以上且 0.08 倍以下（见图 1）。 测试温度范围为10°C至35°C。 适用于十字形试件标距面积的塑性应变量取决于力比、臂的狭缝宽度、加工硬化指数（n 值）（参见附录 B）和测试材料的各向异性。 [外文原描述]： This document specifies the method for measuring the stress-strain curves of sheet metals subject to biaxial tension using a cruciform test piece fabricated from a sheet metal sample. The applicable thickness of the sheet is 0,1 mm or more and 0,08 times or less of the arm width of the cruciform test piece (see Figure 1). The test temperature ranges from 10 °C to 35 °C. The amount of plastic strain applicable to the gauge area of the cruciform test piece depends on the force ratio, slit width of the arms, work hardening exponent (n-value) (see Annex B) and anisotropy of a test material.
