Meaning of program variable

Thank you for contributing this code. I'd like to ask about the specific meaning of 27 variables?
The input parameter 27 (tol = props(27)) corresponds to the tolerance of the Gurson potential (phi) assigned for the iteration. This can be varied considering the accuracy and the processing time.
I mean, all variables

In ABAQUS, the volume fraction of nucleation cavity fn, nucleation strain en, standard deviation sn. In your code, I found fndev, fnamp, fnmean and fsdev, fsamp, fsmean. I want to understand the meaning of all your variables
I have uploaded the documentation of the numerical implementation. I hope it'll clear things up. Thank you.
I have seen the PDF file you uploaded. Thank you very much for your contribution. I'm sorry to disturb you for the second time. I checked the two literatures you cited and the original document "analysis of the cup cone structure in a round tensile bar, Acta metallurgica".
I found that the expression of void volume fraction f in the code was something wrong, it should be ‘f = fc + (1.d0/q1 - fc)(fs - fc)/(ff - fc)’instead of ‘f = fc + 1.d0/(q1 - fc)(fs - fc)/(ff - fc)’.
If I disturb you, you can refuse to respond to me. But I still hope to have your reply.
Sincerely！
You are absolutely right. That's an error by me and I'll modify it in the code. Thank you for pointing out.
