Researchers at the University of Sheffield Advanced Manufacturing Research Centre with Boeing have matured their capability for measuring residual stresses in high-value manufactured aerospace components.

Residual stresses can be produced and affected by a range of manufacturing processes, including heat treatment, machining, and surface treatments such as shot peening. The fatigue life of a component has a direct correlation to the residual stresses that it inherits during the entire manufacturing process, therefore understanding the evolution and interaction of residual stresses during the whole manufacturing chain is of utmost importance.
