Hello,
I like to modify the material-parameters q of the porous metal plasticity (GURSON-model) as solution depended parameters ( = f(strain, etc.) ).
Thought that defining solution depended field variables with USDFLD would be the right way. Is there only the tabular way to connect the field variable solution with the material parameter, no possibility like field(1) = q1 , field(2) = q2?
With only one dependence (my first modification, only f(strain)) the tabular way is possible, I can prepare dependence in Excel. But with more dependences it´s impossible, so I have to calculate it direct.
general question:
It´s correct that there is only one “active” field-column in one material property option? If I already use Field 1 for Young Module I have to use Field 2 for q and Field 1 stays empty?
(informations from here: )
Thank you
Regards,
Philip
