Fabio proposed the following answer:
Jacopo,
please, open a new question with a different subject and try to be more specific on what is your goal: the crash test of an aircraft is too general and too vague... on a soil? on a concrete wall? Do you want to simulate the entire aircraft ? (it seems hard to do!) 
What is the deformable/crushable object? the impacting wall or the aircraft or both? in the second and third case I think it is hard to simulate with a discrete element code... you have to choose simpler objects and simpler shapes (like a bullet for example).
If the impacting wall is low-strength and/or highly deformable, maybe the aircraft could be represented as a rigid object... but again, what is the model that you are representing? Open a new question.
Regards 
Fabio
