The key objectives of this experiment are to obtain residual stress to provide an understanding of the evolution of residual stress as a result of quenching and machining. Furthermore to understand the variation of residual stress along the length of the components whilst also comparing residual stress states in the forged and machined geometries to deduce the effects of machining on residual stress redistribution. Geometry effects will also be investigated, such as the tapering of sections and residual stress relaxation along the length of a beam. Additionally validation of previous measurements using other techniques will also be facilitated, ultimately providing invaluable data for future design and implementation of such components in the aerospace industry.
