How can I explain that the residual stress can shift some xrd peaks in one direction, and other peaks in the opposite direction for the same sample?

This is may be due to the need to balance stress at grain boundaries, and satisfy constraints on the strain tensor (for example a tensile stress along one direction must be balanced by a...
