Zhicheng Gao is still having a problem:
Dear Karol,
I have read the papers you recommended. In my opinion, the second paper
analyzes the parameters of the Ip2_CohFrictMat_CohFrictMat_CohFrictPhys
where the rolling stiffness is determined by ks*αr *R1*R2, so we specify
the rolling stiffness by setting the dimensionless rolling stiffness
'alphaKr' which refers to αr.
My question is whether Ip2_FrictMat_FrictMat_MindlinPhys and
Ip2_CohFrictMat_CohFrictMat_CohFrictPhys use the same rolling resistance
model. In Ip2_FrictMat_FrictMat_MindlinPhys, there is no dimensionless
rolling stiffness parameter 'alphaKr' but only rotational stiffness for
moment contact law 'krot'. Is 'krot' equal to ks*αr *R1*R2 ?
Cheers,
Zhicheng
