GB/T 31930-2015 in English

《GB/T 31930-2015金属材料 延性试验 多孔状和蜂窝状金属压缩试验方法》由TC183（全国钢标准化技术委员会）归口，TC183SC4（全国钢标准化技术委员会力学及工艺性能试验方法分会）执行，主管部门为中国钢铁工业协会。
本标准适用于具有50%或更高孔隙度的多孔状和蜂窝状金属,利用压缩试验方法测定压缩强度第一峰值、平台应力、平台结束点、吸收能量、吸收能量效率、准弹性梯度、弹性梯度、规定压缩应力及规定抗压强度等特征值。压缩试验是在室温下进行的准静态应变试验。

Scope

This standard applies to porous and honeycomb metals with a porosity of 50% or more, using the compression test method to determine the first peak value of compressive strength, plateau stress, plateau end point, absorbed energy, absorbed energy efficiency, quasi-elastic gradient, elasticity Characteristic values such as gradient, specified compressive stress, and specified compressive strength. Compression tests are quasi-static strain tests performed at room temperature.
