Calculate the residual stress on a beam after bending

[QUOTE="onatirec, post: 6530575, member: 686233"] the negative stress appears to be the residual stress after relaxation. Seems you are plotting not the middle of the bar (which would be right along the neutral axis) but perhaps the middle of the the lower surface; it's put in tension during the bending, would be in slight compression after unloading. I'm curious as to how we are defining "residual stress on a beam" - peak?. I would suspect that the total residual stress state would be geometrically distributed and would want to find an equilibrium (obviously this isn't mathematically precise); there would be contributions from both tension and compression as seen above.
