塑性应变比 [
sù xìng yìng biàn bǐ]
[力] plastic strain ratio
- 基面织构减弱和塑性应变比的降低是板材室温成形性能提高的根本原因。
The weakened (0002) basal texture intensity and lower plastic strain ratio are thought to be mainly responsible for the enhancement of room temperature formability. - 实验结果验证了花岗岩的塑性应变主要与偏斜应力产生的形状改变比能有关,而与体积改变比能的关系不大。
The experimental data show that the plastic strain of granite mainly depends on the strain energy of distortion due to deviatoric stress, but not on the strain energy of volume change. - 研究结果表明,FVS0812板材具有较小的延伸率和塑性应变比,较大的屈强比,FVS0812板材的冲压成形性能不佳。
The results showed that elongation and the coefficient of normal anisotropy of FVS0812 sheet were low and yield ratio was high, which means the stamping formability of FVS0812 sheet was low.
