   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).
