Additional information
This paper reports the main findings from an EPSRC/MOD funded project, on which an impact case study UOP12FOD is also based. For the first time 3D residual stresses from foreign object damage (FOD) and laser shock peening (LSP) were evaluated and used to obtain an effective stress intensity factor, which was then used to rationalise the fatigue crack growth under simulated service conditions. The results have provided increased confidence in using LSP in FOD susceptible components (UOP12FOD). The generic method developed is also applicable to crack growth in a residual stress field, for example, in welded structures.
