Hi everyone, has anyone implemented the Drucker-Prager criterion in PySPH?
If so, could you please share an example or reference to the implementation?

Thank you very much
Martin

Hi Martin,

Unfortunately, I am not aware of a well tested Drucker-Prager implementation in PySPH. One of the graduated students in my lab may have an implementation and I have reached out to him.

Regards,
Prabhu

Hi Martin,

  Sorry for the late reply. I have DP implemented and would be happy to share it with you. This version I implemented works as far as I know, but you would probably like to validate it in any case. Is there a preferred way to share the file with you?
