✦ Synopsis

In this paper a design procedure for fatigue assessment of welded pipe penetrations in plated structures is presented. The background for the procedure is given. It applies to full penetrations welds, partial penetrations welds and fillet welds. Fatigue cracking from the weld toe and from the root of fillet welds is considered. The procedure is based on calculated stress concentration factors using finite element analyses for relevant geometries of penetrations through plated structures. Numerical examples using the procedure for calculation of number of cycles to failure are presented. These numbers are compared with fatigue test data from specimens that were fatigue tested at the Technical University of Trondheim and Kungliga Techniska HΓΈgskolan in Stockholm.

This paper is concerned with the design of complex welded structures subjected to fatigue loadings. In the last years it has been developed a new approach for predicting the high cycle fatigue behaviour of welded joints, based on the Notch-Stress Intensity Factors of the uncracked geometries, which
