Variable Elasticity (Young) Modulus
Fri, 2011-01-28 15:02 - chibalx
I need to simulate a sheet forming but I must consider the variation of Young modulus with plastic strain.
Has anybody tried this? How can I implement a function for this? I have never worked with UMAT / VUMAT.
Thank you.

I've tried this but not
I've tried this but not with a UMAT. I write a USDFLD / VUSDFLD and it works well.
There's a good example in Abaqus User Subroutines Reference Manual. For version 6.8, it's at §1.1.43. You can modify this example by calling variable "PE" and then define field(1)=array(7) which is variable "PEEQ".
Thank you. I will try.
