Abstract

In the LSED approach, the fatigue strength of welded joints is quantified by the value of the strain energy density averaged over a control volume of radius Rc near the sin- gularity-dominated zone. Unfortunately, the characterization of such parameter is far from being fast and simple since it requires different fatigue tests on notched and un- notched specimens. For this reason, a complete database of Rc values corresponding to different materials is still lacking in literature. This work is aimed to quantify the Rc value of a 2205 (UNS S32205) duplex stainless steels by means of fatigue tests and metallurgical analyses.
