Personnaly, I don't know how to scale the model adequately for debris transport problems, and I suspect nobody knows...

Then all you need is to set the tensile strength value using Python interface. Be carefull about "links" if you think "permanent links". The "link" concept is being removed from Yade slowly, we only have "interactions" now.
