Abstract
Butt welds are one of the most common structural details in wind turbine steel towers. In this paper, results from fatigue tests on butt welds in the as-welded and grit-blasted conditions are presented. In addition, finite element analyses were performed using the effective notch stress and the crack propagation approaches. By using macroscopic measurements and three-dimensional scan, the notch effect of the weld seam was considered. These results were compared with results from fatigue tests. On the basis of a successful alignment between simulation and experiment, the possibility to discuss the fatigue resistance influencing variables from the seam geometry is presented.
