No, dwood is saying that a spoke does not go beyond yield once it is tensioned in a wheel. There is elastic stretching. This is true and nothing will cause a plastic deformation. A plastic deformation will only happened if something hits the spokes, like your derailer or if the rim fails and tacos.
A suggestion for T-Turtle: don't believe everything you read that has been written by 'bicycle experts' even if they claim to be engineers. I suggest you do some independent study in the Mechanical Engineering field. |

There is some. Have you ever taken out a spoke and it has a bend in it? That is a plastic deformation. But I was saying that stress relieving does cause some plastic deformation (disputed by dwood). Once the wheel is built and tensioned, there should be no more plastic deformation.
I also meant that there is no normal force that will cause a plastic deformation. Once a wheel is built, the spoke will only plastically deform from some outside force, like a stick in the spokes. |
