| 摘 要： | 通过拉伸试验研究了在"缺口效应"影响下塑性金属材料试样不同截面处的塑性变形规律及其它常规力学性能指标,结果表明所试验金属材料缺口拉伸塑性变形主要集中发生在缺口附近局部区域,同时探讨了增加"缺口塑性"这一新的性能指标及建立相关试验标准的必要性。

| Abstract: | Under the influence of notch effect,plastic deformation and other mechanical behavior parameters on different section of specimen about plastically metallic material were studied by means of tensile testing.The results show that plastic deformation of tensile specimen is mainly concentrated in the local zone of adjacent notch.Meantime,the necessity about establishment of notch plasticity parameter and related testing standard was also discussed. |
