Bruno Chareyre proposed the following answer:
> What if [...] trsfNew = trsfOld+dt*velGrad

It would introduce severe inconsistency for large deformations.
Just like using the cross product for computing a large rotation.

You say you want to control strain rate. Strain rate _is_ velGrad
(actually its symmetric part). I don't get your point.
