saif, hi... strain what? Can you please clarify what your subject is? Does it have to do with physics or chemistry?

[saif]

Thanks for your asking

It is about physics

Stress-strain curve , steel hardning and machines used for that test.

Hi wrong subject wrong moment

I don't have any research paper on strain hardening, but I can give you the procedure how to find out the strain hardening exponent from your load-displacement data. If you are loking for one of the research papers, I think it should be from 50's or 60's. If you need the procedure, let me know.
Good luck
