[gmx-users] can gromacs investigate mechanical properties of a molecule?

dear gmx crew,
I'm working on a project which is aimed to study the mechanical features of alpha-actinin, a 100 kDa protein involved in the structure of cell's cytoskeleton.
This is what I'd like to do: after optimization of the .pdb file, perform some elongation simulation, by restraining the distance between the two terminal atoms (I've already done some testing like that with a software called "hyperchem", but every elongation step required almost ten hours...). So, I'll eventually get the relation between Energy and elongation.
Then it would be nice to reproduce the viscoelastic behaviour of the protein, performing some creep or stress relaxation test.
Do you guys think that gromacs can do that? Has anybody already done something similar?
