A numerical model is developed to predict the combined effect of a weld toe undercut, residual stresses and mi~alignment on the fatigue strength and fatigue life of butt welded joints subjected to pulsating tensile loading. Linear Elastic Fracture Mechanics (LEFM), Finite Element Analysis (FEA) and
Residual stresses have in the past been introduced to manipulate growth rates and shapes of cracks under cyclic loads. Previously, the effectiveness of shot peening in retarding the rate of fatigue crack growth was experimentally studied. It was shown that the compressive residual stresses arising f
## Abstract Residual stresses due to the welding process in steel structures can significantly affect the fatigue behaviour. Usually, high tensile residual stresses up to the yield strength are conservatively assumed at the weld toes. This conservative assumption can result in misleading fatigue as
