I am trying to simulate indentation process on stressed material. Problem is whenever I try to introduce initial stresses from SIGINI subroutine in axisymmetric model, to balance stresses, original stress field changes. When I do this in 3D model it works fine but for axisymmetric model as I cant introduce displacement control constraint at edge of axisymmetric, stresses relax towards the side of axisymmetric constraint.
Any idea or example of maintaining resdiual stresses in axisymmetric model thorugh SIGINI?

Sorry if I cannot answer to your problem but I'm really interested in apply residual stress in a model with subroutine SIGINI, can you help me with some example o just sending me the subroutine file? thank you
