The residual stress that I am talking about is mostly tensile and thermally induced. The stress is observed on the surface only upto a very small depth in the thickness direction. Is this kind of stress significantly damaging from a fatigue perspective?

Also, what would be effect of the residual on the strength?

Is it possible that some sort stress relaxation could occur and the residual gets dissipated?

What is the significance of these stresses from strength and fatigue perspective. Are these stresses still relevant for results interpretation? Is there a possibility of misinterpretation when using these in gas turbine assesments (or complex designs with thermal and mechanical loading)?
