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).
