dc.description.abstractThe objective of this work was to investigate the effect of ultrasonic peening on the fatigue propagation life for a semi-elliptical flaw at a T-butt weld toe. A number of T-butt joints have been fabricated from 10 mm thick A350 grade black mild steel plate. Through-thickness residual stresses at the weld toe have been measured using neutron diffraction for both as-welded and ultrasonically peened joints. Ultrasonic peening is relatively cheap, can be applied in-situ and offers significant improvements in the lifespan of welded components when applied correctly. Numerical analyses were conducted using BDKH stress intensity and HBC stress distribution parametric equations in conjunction with the Paris Law and Forman Equation fatigue crack growth models.en_AU
