I think you need to provide more details for clarity. What type of structure are you analyzing? What type of stress/component of stress are you observing? Are you observing this stress at a point/on a surface or for the whole structure? What type of displacement/its component are you referring to? Etc.
So il work in the software Ansys apdl. I work on a minaret of 30 m high and I put 4 then 6 sma and I compare the result of the seismic response. I observe the stress in a node. and the displacement it's a displacement in a point
