请问什么是强化模量（strain hardening modulus ）？谢谢！

If you have a stress-strain curve from a uniaixal tension test, you will see that you will have the elastic moulus when the material is elastic. Then after the material yield, you can see that the slope of the curve is not zero and that slope is called plastic modulus caused by strain hardening.

谢谢您的回复！跟后屈曲模量一样，
