Hello,

       Infact, abaqus user manual is not the only source to learn how to write user subroutines. But, one should be familiar with the abaqus conventions initially. I suggest you to look at  this book (http://www.amazon.com/Introduction-Computational-Plasticity-Fionn-Dunne…) and download the codes given in the appendix of the book, (http://www.eng.ox.ac.uk/NP/ICP/). I hope this will help you to code your own UMAT.

Thanks and Regards,

Rohith
