[Question #699705]: Empirical value of rolling stiffness (Krot)


New question #699705 on Yade:

Since Ip2_CohFrictMat_CohFrictMat_CohFrictPhys is a linear model, and Hertz-Mindlin contact law is a non-linear model that is often used, so I choose to use Ip2_FrictMat_FrictMat_MindlinPhys. 
However, in many documents, only the value of the rolling friction coefficient is given, and the value of the rolling stiffness is not given. In the  Ip2_FrictMat_FrictMat_MindlinPhys, the rolling friction coefficient is given by eta, and the rolling stiffness is given by Krot, so what is the appropriate setting for the rolling stiffness? Is there any related literature?
