“…The crack growth conditions for mixed modes I + II and I + III (realized by combinations of tension, bending, and torsion) were shown in Rozumek et al 8 Seitl et al 9 provided experimental comparison of long fatigue crack growth rates for two subgrades of structural steels (S355J0 and S355J2) and the study of the influence of chemical composition and structure texture of the steels on the long fatigue crack behavior. The experimental results ascertained for S355J0 steel grade and for the stress ratio R = 0.1 were analyzed and evaluated by Seitl et al 10 by using advanced ProFatigue and ProPagation software. The experimental results were discussed in relation to the results presented by de Jesus et al 2 and Adedipe et al 11 .…”

The paper brings results of high-cycle fatigue and very-high-cycle fatigue tests of the steel S355 tested during low-and high-frequency loading. Two grades of structural steel (S355J0 and S355J2) were tested to gain fatigue properties that serve as inputs to reliable finite element calculations of cyclically loaded structures. Experimental measurements of both steel grades were performed on low-frequency hydraulic and high-frequency ultrasonic fatigue testing systems. Both low-and high-frequency loading showed higher lifetime for the grade S355J2. The difference between the two studied steel grades was more apparent during low-frequency loading. The significant difference between the results of low-and high-frequency loading tests can be explained by the fact that the resistance to plastic deformation increases with an increasing rate of deformation. Fracture surfaces were studied by electron microscopy, where they exhibited both surface and internal crack initiation.
