Structural analyzes for welds

The assessment of welded structures can be made with both analytical and numerical methods. For standard weld details that are listed in catalogs notch case, the nominal stress concept is used often. However, if non-linear stress waveforms are to be assessed in complex welding details, then get local concepts used, e.g. to determine the stress concentration at the weld toe and the weld root. The following figure shows a finite element mesh for both sides welded butt weld to assess the notch stresses at the seam transitions.
