Thanks for helping.  The constitutive law is relevant but not entirely.  An example of a problem that I would like to look at is wedge stability of slopes.  E.g., create two joint planes intersecting the corner of a box, and the wedge will slide.  

I'm not looking at brittle fracture of bonded material, but would like to know how to insert a joint plane before simulation.  So far, I've only stumbled across particle generation in YADE.

 

 

Yours sincerely,

 

Boon

I don't think anything like this is implemented yet. It is difficult for me to give advices without a precise explanation of the modeling you want. If you need the list of interactions intersecting a plane, it should not be too hard.
Something like :

FOREACH (interaction)
{
  if (interaction->body1 on one side && interaction->body2 on the other side)
   intersected_list.push_back(interaction)
  //or simply
   modify_properties(interaction)
}

I guess you don't need that at each iteration, so performance is not an issue.

I am planning to use YADE for rock engineering.  The joint i was refering to is a joint plane.  I would initially like to have a block of rock mass.  And by specifiying the dip direction and dip angle of the joint planes, the block of rock mass will be cut/intersected.  Then I will have to identify the polyhedral blocks formed from the joint planes.    Does anyone know how to do this? Or has done it?
  Yours sincerely,
 Boon
