Chareyre proposed the following answer:
Actually, the strain tensor is simply not defined (only the diagonal term is).
Had it to be defined, then we would have to choose between various large strain formalisms, but why would we do that?
The only thing you have is the transformation matrix, and I think that most authors are using it to define the shear amplitude.
If you shear along (x,y), then O.cell.tsrf(x,y) will give you the displacement/height value.
