Change Material property during iteration step

[MyNameIsUser]

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

Hi,

change material properties during a jobs iteration

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

goal is to evaluate each mesh element after an iteration and change its material properties depending on the stress level.

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.
