摘要
通过对比 σp0 .2 与 σr0 .2 间的关系、σp0 .2 与 σr0 .2 的测定步骤、力学性能试验技术的发展和 GB/T30 77- 1 999标准中力学性能指标的用途 ,指出在 GB/T30 77- 1 999标准中用σr0 .2 代替σs是不合适的。
By comparing the definitions and test procedures of σ p0.2 and σ r0.2 , considering development of mechanical testing technology as well as purpose of mechanical test indexes in GB/T 3077-1999, it was pointed out that it is was unsuitable to substitute σ s with σ r0.2 in the new version of GB/T 3077-1999.
