Another way to create automatically the user subroutine UMAT is by automatic UMAT code generation procedure for pseudoelastic materials using the symbolic mathematics package Mathematica, described in the article "Automatic Generation of User Material Subroutines for Biomechanical Growth Analysis", here, and also here.
We found the PhD thesis where many interesting details of the Mathematica implementation for FORTRAN UMAT subroutine generation and examples of the subroutines itself are available.
In this thesis the author claim that they have published the Mathematica notebooks in the Journal of Biomechanical Engineering ASME as supplemental material, where it is free to access and download. Unfortunately, we failed to find these notebooks on WEB. If you know how to get it - please comment it.

On the website of University of Rochester the document is free and fully available! :)
Thanks for your comment :-). The thesis itself is indeed is fully available on website of University of Rochester as I marked above in the topic (https://urresearch.rochester.edu/fileDownloadForInstitutionalItem.action;jsessionid=720B5B0128DD77BDF712A9903A5E74C7?itemId=12504&itemFileId=28720) and contains the Mathematica Code on page 133. Perhaps Young.zip with a restricted access is the Mathematica notebook. But we are naturally lazy men and we have tried to arrange it so that nothing should make us move. Therefore I point out on the non-availability of the code itself.
