Need Help regarding UMAT subrouitne
It's been 2 weeks, I strated to use abaqus and user subrouitnes. To understand the how user subroutine work I thought to run some UMAT which I got it from http://imechanica.org/files/Writing%20User%20Subroutines%20with%20ABAQUS.pdf (page no- L6.73) to analysis a 3d steel plate with the material property which is given below.
I don't know where went wrong the plastic strain (PE,PEEQ)result is not showing or I don't have the knowledge of understanding as beginer of abaqus user, Please any suggestion will be helpful.
If I'm not able to run this code I will be in big trouble , any suggestion will be helpful for me . Thanx in advance....

subroutine
Hello
ABAQUS is unable to interpret your subroutine as an implementation of plasticity. You get PE and PEEQ only if you use the standard command *PLASTIC.
In the future:
