Objetivo Although there is a wealth of information on the fatigue performance of welded carbon-manganese structural steels, welded stainless steels have been neglected. Consequently, there is little data available upon which to provide design guidance, particularly in the case of duplex steels. Therefore, it is proposed to carry out a thorough study of the fatigue behaviour of welded austenitic and duplex steels, to investigate any differences between them and structural steels and to provide design guidance. The research project includes the following: - fatigue endurance tests of typical welded joints in plates and tubes; - fatigue crack growth and threshold tests;- metallurgical and fractographic examinations to establish the influence of microstructure;- residual stress measurements;- fatigue life modelling using local strain and fracture mechanics concepts.
