strain hardening rate

The higher initial strain hardening rate and higher strength of dual phase are attributed to rapid strain hardening in ferrite and the load transfer from the ferrite to martensite.

铁素体迅速应变硬化和铁素体到马氏体的载荷传递使双相钢具有较高的初始应变硬化速率和较高的强度。

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。
