Hammering task problem being a softbody problem or not?

[twanschik]

Sorry for posting this question here but i do not know where to post it otherwise. So here is my problem:
I want to simulate a hammering task, where an arm tries to hit a nail with a hammer in order to put the nail into a board. The nail should be deformable, the hammer obviously not. But i am not sure if the deformation of the nail has to be simulated via softbody dynamics or not?

I am new to bullet but not to physics because i study physics about four years now.

So maybe someone can help me.

Another question: Do you think that this task is rather complicated or not (taking the constraints of the board to the nail into account).

Thanks,
Thomas
