strain-rate hardening

Further more, a damage softening constitutive model is set up in which the effect of fiber reinforcing and strain-rate hardening are considered.

并建立了一种包含纤维增强效应和应变率增强效应在内的损伤本构模型。

Test results show that for the stress-strain curves with no obvious peak strain, it is a available to use work hardening rate method to determine peak strain and stable strain.

实验结果表明，对于无明显峰值应变的应力-应变曲线，采用加工硬化率方法确定峰值应变和稳态应变是一种有效的方法。

The model includes the effect of strain rate sensitivity, strain softening and strain hardening.

该模型包括了应变率敏感性效应，应变软化效应和应变硬化效应。
