“…However, in the special cases of a plane the surface consists entirely of umbilic points, and there is no orthogonal net of principal curvature directions. Therefore, for a flat mode I crack there is no geometric constraint on permissible crack front families, and a wide range of crack front families is possible and, indeed, observed [69,84,85].…”

“…Surface flaws in flat plates tend to follow preferred fatigue propagation paths, i.e. the flaw aspect ratio is a function of the relative crack depth for both axial and bending cyclic loading [7,19], and an analogous conclusion has also been drawn for edge flaws in round bars [3,5] and pipes [14]. Such analyses have generally considered a bending moment acting about a principal axis of the beam cross-section.…”

The propagation of a surface flaw in a cylindrical shaft subjected to rotary bending is analysed using a two‐parameter theoretical model. The stress‐intensity factor distribution along the crack front is numerically determined for any position of the flaw with respect to the bending moment axis. The crack front is assumed to present an elliptical‐arc shape with aspect ratio α = a/b (a, b = ellipse semi‐axes), whereas the relative depth ξ of the deepest point on the front is equal to the ratio between the maximum crack depth, a, and the bar diameter, D. The results for rotary bending are compared to those for reversed cyclic bending.

“…The theoretical and experimental analyses on simple semi-elliptical surface cracks in plates and bars (see e.g. Görner et al 1983, Caspers et al 1990, Mahmoud 1990) were extended to more complicated crack problems as for instance almond-and sickle-shaped cracks in rods (Görner et al 1983) and corner cracks (Varfolomeyev et al 1991).…”

A Residual Stress Intensity Factor Solution for Knoop Indentation Cracks

The residual stress intensity factors at the surface and at the deepest point of the semi-elliptical Knoop indentation crack is determined from the stresses in the damaged zone below the indenter. For this purpose, the weight function approach by Cruse and Besuner was used and wide-range expressions of the geometric function are given. The solution is then applied to a commercial silicon nitride for which all relevant geometrical data are available.
