✦ Synopsis

Abstract

In the present paper a method is described for the fatigue assessment of multi‐axial loaded welded joints in structures made from thin steel sheets. The focus is on seam welds under non‐proportional loading, assuming a constant angular phase shift between cycles leading to stress components acting at the seam welds. Fatigue analyses are using a local stress approach based on stresses derived by Theory of Elasticity. Furthermore, potentials of considering statistical size effects in order to analyse weld start and end points are outlined.

## Abstract The numerical fatigue assessment of seam welded joints is of significant importance in automotive industry. In order to use the fatigue concepts, which are available in the literature, in series calculations, they usually have to be implemented into commercial software programmes. In th
