Hi Luc,

The CohesiveFrictional contact law is very general, it includes normal, 
shear, bending, and torsion components (bending and torsion are purely 
elastic for now, it is no big deal to add a threshold for failure). You 
could start with this law and add missing features, or perhaps derive a 
new law from this one if you need much more sophistications.
