Is there an idea to open a part of forum regarding constitutive models and their implementation to GeoXPM?

Hi @vjagodnik
Thanks for the suggestion. I think it's a good idea. I have opened the 'Constitutive models' section.

Dear sirs,
I would like to have further details about the parameters governing the Drucker-Prager with softening. What the parameters "a" and "b" represent? In addition, which is the softening law implemented in the software?

Please find a description of the Drucker-Prager softening model in this paper:

Hello,
Do you have any template for user-defined constituive model?
Regards,
A

@alrm You can find the template on the Examples page for the User-defined Constitutive Model https://geoxpm.com/materials/
It's this one https://geoxpm.com/wp-content/uploads/2023/06/GeoXPM-User-defined-Constitutive-Model-Template.zip

I would like to have further details about the parameters governing the Drucker-Prager with softening.What is the relationship between parameters "a" and "b" and the softening coefficient?
