Re: How is the cohesion treated in YADE?

 


is the cohesion property of some kind of material (like rock) treated in YADE?
if so, how it is modeled? bonded model?
   Hello. It depends on the contact law you use...
For example you could have cohesion in CohesiveFrictionalContactLaw (see the files in pkg/dem/Engine/StandAloneEngine/). For each interaction a value of cohesion "c" named in fact "shearAdhesion" is computed depending on a caracteristic "shearCohesion" (member of the class "CohesiveFrictionalRelationships) and on the radii of the bodies in contact. This value of cohesion will then be used for computing a maximum value of tangential contact force : Ftmax = c + Fn * tan(phi).
