Hi all,


How I can add rolling stiffness coefficient and plastic moment limit coefficient to frictional material property: it seams  "alphaKr" and "etaRoll"  just have been defined for CohFrictMat not FrictMat .

e.g. O.materials.append(CohFrictMat(alphaKr=1.7,young=30e6,poisson=0.4,density=2600,frictionAngle=radians(36.5),normalCohesion=1.3e6,shearCohesion=1e6,momentRotationLaw=True,etaRoll=.4,label='spheres'))

How I can see these parameters in frictional material since, to me are not just related to cohesive materials.

Thanks 
Seti
