Residual Stress

 

the stress that remains in a solid body once all external forces have been removed. A residual stress develops in a solid when the external forces elicit both elastic strain and plastic flow.

residual stress

A stress that remains in an unloaded member after it has been formed into a finished product, such as that induced in steel shapes by cold bending, cooling after rolling, or welding.
