The tensile stress across a persistent slip band in a fatigued specimen is considered. It is demonstrated that the stress concentration produced by a fatigue crack promotes the circulation of screw dislocations around the crack and that the direction of circulation is such as to punch the crack deeper into the material prismatically. It is suggested that extrusions, intrusions and cracks are produced by the Mott mechanism, driven by stress concentrations.

This paper reports on an investigation into the effect of notches and other stress concentration features on the high-cycle fatigue strength of polymethylmethacrylate. The material was used in a porous form, as is found in bone cement and other medical applications. Sharp notches and circular holes
A theoretical solution for centrally notched fixed-pinned ended column loaded concentrically or eccentrically in compression has been presented. The solution is based on the stress intensity concept and on methods of limit analysis. The experimental and theoretical results have been found to agree t
