RR938 – Residual stress measurements and modelling

Residual stresses are unavoidably generated in components after welding. Tensile residual stress in engineering structures generally has an adverse effect on structural integrity. It can cause detrimental effects on brittle fracture, corrosion properties and fatigue performance. There is strong interest in the offshore industry to better understand the magnitude and the distribution of through-wall thickness residual stresses. This report describes the work carried out and the results obtained.
