Hi liucheng83,

Due to rolling resistance, there are 2 bending DOFs and 1 twisting DOF.
The normal (relative to contact plane) component of (omega_1-omega_2)
contributes to bending DOFs.

==>And is etaRoll or alphaKr in class yade.wrapper.CohFrictMat()
correspond to rolling resistance, while alphaKtw correspond to rolling
resistance twist resistance.

You are right.
