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。
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.
并且给出用与切线模量相关的标准确定加工硬化型应力——应变关系曲线的破坏点的方法，提供了利用任意固结度下的应力路径求解不排水抗剪强度的计算式。
The method to ascertain the damage point of process harden type stress-strain curve was shown, and the calculate expression of shear strength used by stress path under random consolidation degree.
当应变量大于5%时，应力随着应变的增加而缓慢增加，加工硬化速率降低。
The stress increased slowly with strain increased when strain was above 5%, and work hardening rate decreased.
