It should work.
This law is relatively general. You have to tune it to choose between 
fragile or perfectly plastic behaviour (the first would be better for 
rocks, the second seems more realistic for soft soils), and also decide 
if contacts created during the deformation will be cohesive or not.
It can include bending/torsional effects too, but those components will 
be only elastic for now. It is no big deal to add a plasticity  threshold.
If you need a cohesive law, I recommend using this law as a basis and 
adapt it to your specific needs instead of starting a new class.
