Yade

Cohesive and viscous-elastic contact law

Asked by Luis Barbosa

Hi,

It is common in YADE model of spring-dashpot in parallel, for normal compression and tangential. However, is there any contact law that include cohesion to that model?

I think that would be some thing like:
Law2_ScGeom_MindlinPhys_Mindlin + Law2_ScGeom6D_CohFrictPhys_CohesionMoment

Thanks,
Luis

Hi,
No, as far as I know. There is no law functor combining adhesion with this type of viscous damping.

Hi Luis,
did you check the includeAdhesion option in the Hertz-Mindlin law? The description is not very detailed, but you can check the code to see, if that is what you want.
Regards,
Bettina
