Hi all,
I am checking the contact model used in the software. But I find the contact model in the EDEM help file, where the damping coefficient is different from all the references listed. I can not understand what is the constant item at the begining of the expression of Hertz-Mindlin (no slip) model. Can anyone explain or give me a reference about this?
Thanks!

Hi Stephen,
Thank you for the reply.
I checked those references, but I didn't find this expression used by EDEM software in those papers. Can you please give a specific reference where the damping coefficient that I attached in the previous question comes from? We need it when we are writing papers about the simulation by EDEM.

Hi,
You can check:

or

This is helpful. Thank you very much, Stephen.
