“…In comparison to the literature data, a larger slope of the quantile curves, as well as a larger scatter band under seawater conditions, is visible. At approximately 2 · 10 6 load cycles, a transition to the fatigue data of Milovanović et al 33 and the FKM guideline can be observed. According to Klusák et al, 34 the structural steel in distilled water shows a significantly higher fatigue strength and a very flat slope of the quantile curves.…”

“…Figure 7 illustrates the SN curve received with the structural steel S355J2C + N under the influence of artificial seawater. For comparison reasons, the data series of Milovanović et al 33 under air conditions, the recommendations according to the FKM guideline, 32 and the SN data by Klusák et al 34 are also plotted in Figure 7. Klusák et al 34 used a closed circuit of flowing distilled water for effective cooling of their specimen during the ultrasonic fatigue tests.…”

The fatigue properties of a high-strength steel, a structural steel, and a duplex stainless steel in artificial seawater were investigated. Consequently, a test chamber for the existing ultrasonic test stand was implemented. The experiments were performed with smooth specimens at a loading with R = À1 up to 2 Á 10 9 cycles. The specimens were fully submerged in artificial seawater. The fatigue data were statistically evaluated using the pearl string method and compared to different SN curves from the literature in air. The results show continuously decreasing SN curves under seawater conditions for all materials, with no detectable fatigue limit. Fracture surface investigations reveal large corrosion areas for the structural steel with, generally, no clear crack initiation location. The duplex stainless steel shows less corrosion pits but a high degree of scatter of the SN data. For the high-strength steel, multiple crack initiation locations were observed from the surface.

“…Due to good mechanical properties, easy processing, forming, good weldability, and crack resistance as well as low price, structural steels are widely used in industry. S355J2+N steel is most often used for the production of load-bearing parts of structures exposed to dynamic loads and low temperatures [29,30]. AA1050 in the H24 temper was used as an intermediate layer between the AA5083 alloy and the S355J2+N steel to join them in the explosive welding process.…”

The study presents an analysis of S355J2+N steel and AA5083 aluminum alloy welded structural joints using explosion welded transition joints of reduced thickness. The transition joint thickness reduction significantly hinders the welding of the joints due to the risk of damage to the Al/steel interface as a result of the high temperatures during welding. In the previous article, the strength of the transition joint was analyzed but ship structures, apart from static loads, are subjected to many different cyclical loads. Welded structural joints are analyzed to determine the welding influence on the fatigue life and fracture type of the transition joints. The results of the fatigue tests show that the fatigue damage in the specimens occurs in the aluminum welded joint, and not in the explosively welded joint. The damage obtained was characteristic of cruciform welded joint specimens and both types of root and toe damage occurred. Based on the obtained results, fatigue curves for the joint were determined and compared to the fatigue curves for the AA5083 base material. The experimental fatigue curve was also compared with the design curve for welded aluminum structures from Eurocode. The conducted analysis showed the possibility of using Al/steel explosion welded transition joints of reduced thickness to transfer cyclical loads.
