Luc Scholtès proposed the following answer:
Hi,
You may already figured out a solution for your problem but here is nonetheless
a suggestion. You could create a simulation where a (bi)periodic packing is
sandwiched between two horizontal plates. The packing would thus have periodic
boundaries along the 2 horizontal directions while the upper and bottom
(infinite) plates will allow you to apply a given normal stress on it and to
shear it. Once the desired normal stress achieved, move the plates to produce
shear. All this can be achieve, e.g., by fixing the bottom plate and by
servo-controlling the upper plate (vertical displacement to control the normal
stress and horizontal displacement to shear the sample). Depending on your
need, you may increase friction between the plates and the sample by fixing the
contacting particles to the plates.
I can provide a script if you think that's appropriate.
