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

Thank you very much
Martin

Hi Martin,

I think Dr. Dinesh has an implementation of this but I am not sure where his repository is. Dinesh, can you help?

Regards,
Prabhu

Hi Martin,

Yes, there is a code repository with an implementation of the Johnson–Cook criterion. However, it is not a fully working implementation yet — there are some issues, including particle leakage.

I am sharing the repository for reference if that helps, but it will likely need fixes before it can be used reliably. Link to the repository https://github.com/dineshadepu/sph_granular_flows/


Regards,

Dinesh

Hi Dinesh,

Thank you very much for sharing the repository and for the clarification about the current status of the implementation.

Even as a reference, this is very helpful. I will take a look at the code and see if I can identify the source of the issues.

Thanks again for making it available.

Best regards,
Martin
