“…3,4 Fatigue properties of S355 steel under bending loading were analyzed in Pawliczek and Prazmowski. 7 They studied the samples of S355 steel under bending, with various mean stress values. 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 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.

“…In both cases, however, the stress conditions during the fatigue test differ from the initial stress conditions due to cyclic changes in the specimen such as softening, hardening, or cracking. An increase in the ultimate strength after cyclic loading prior to crack nucleation is reported in [9].…”

A method for estimating the crack growth rate in steel during rotating‒bending fatigue testing is presented. Constant deflection tests were conducted in which the initial load remained constant prior to crack nucleation, when it decreased as the crack grew. In the proposed approach, steel samples were sharp-notched to produce a characteristic circular fracture upon loading and the final fracture area was correlated with a ratio of the load prior to fracture and the initial load. In this method, the deflection imposed is a function of a material’s elastic modulus rather than its yield strength and the correlation obtained to estimate the average crack length as a function of the instantaneous load is independent of the applied stress or steel grade.
