真应力 [zhēn yìng lì]
[高分子][力] true stress
- 随著流动拉应力的降低，颈缩区域中部的真应力持续增加。
True stress and contraction ratio of the minimum section increases as flow tensile stress decreases. - 结果表明：在实验变形条件下，合金的真应力—真应变曲线为动态再结晶型；
The results show that the true stress—strain curves of the alloy have dynamic recrystallization character under the present deformation conditions. - 随着应变的增大，合金的真应力一真应变曲线在经历了明显的加工硬化阶段后达到最大值，然后渐渐出现流变“软化”现象。
With the increase of true strain, for process hardening of the alloy, the true stress attains the peak, and then flow softening occurred.
