Average mechanics enjoyer is on a distinguished road

I am interested in the finite strain analysis of representative volume elements (RVE) in Abaqus but am having trouble implementing mixed boundary conditions. I realise that periodicity could be handled through multi-point constraints and some "dummy" reference node to represent macroscopic parts of the deformation. I am completely lost however when it comes to incorporating boundary conditions on the macroscopic stress, say to achieve a uniaxial stress state. Does anyone know of a plugin that allows for traction/avg stress constraints or how one could go about implementing this?

All the best
