Change Material property during iteration step

Change Material property during iteration step

Change Material property during iteration step

(OP)
Hello,

I'm fairly new to Abaqus so bear with me:

I'd like to change material properties during a jobs iteration frames e.g. at the second iteration step id like to change my young's module to e.g. 10^9.
How do i do this?
My final goal is to evaluate each mesh element after an iteration and change its material properties depending on the stress level.
Thank you for any help :)

Abaqus feature you are looking for is called field variable.
Check Abaqus documentation: Abaqus Analysis User's Manual, 33.6.1 Predefined fields

To do it you need to use field variable in combination with FORTRAN subroutine USDFLD/VUSDLF and GETVRM/VGETVRM routine.

Use "field" and "usdfld" as keywords to search posts on the forum.
You can find many with detail information how to do it.

Regards,
Bartosz
