“…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

et al. 2012

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.
