“…Fig. 7 shows that the dimensionless SIFs F A and F B for the case of a semi‐circular crack b/a = 1 at the point A and B obtained by different authors 9,11,18–20 are in quite good agreement. In addition, it can be seen that F A is always larger than F B .…”

“…Some authors 4,10,16,18–21 analysed surface cracked shafts using several mathematical techniques including finite element analysis, and considered the correction factor F to be a function of relative crack depth b / D . For example, Carpinteri calculated the SIF of a straight‐fronted edge crack in a round bar for different relative crack depths b / D 10 .…”

A B S T R A C T In this paper, the surface fatigue crack growth shape for an initial straight-fronted edge crack in an elastic bar of circular cross-section is determined through experiments under pure fatigue axial loading. Three different initial notch depths are discussed. The relations of the aspect ratio (b/c) and relative crack depth (b/D) are obtained, and it is shown that there is a great difference in the growth of cracks with different initial front shapes and crack depths. Further, using the three-dimensional finite element method, the stress intensity factors (SIFs) are determined under remote uniform tension loading. Since the relationship of b/c and b/D changes during the fatigue crack growth, the SIFs are determined for different surface crack configurations.

“…are commonly used, and failure may occur under cyclic loading. The fatigue failure of round bars often develops from surface defects, and thus several analyses have been carried out to determine the surface crack shape, crack growth rules and stress‐intensity factor (SIF) along the front of an edge flaw 1–9 …”

A B S T R A C T In this paper, the fatigue life, surface crack extension direction and crack growth rate in an elastic bar with a circular cross section are determined through experiments under cyclic torsion with axial static and cyclic tension/compression loading. The effects of the loading type, loading value and stress ratio on the crack growth behaviour are discussed.The results show that, under pure fatigue torsion loading, the crack extension direction is almost the same whatever the value of torsion loading. Under fatigue torsion with cyclic tension loading, it is found that the crack extension direction is mainly determined by the alternating parts of the stresses and is almost independent of the average parts of the stresses, whereas the fatigue life is obviously dependent on the average stress.
