Review and synthesis of stress intensity factor (SIF) solutions for elliptical surface cracks in round bars under tension loading: A Tribute to Leonardo Torres-Quevedo

In this paper different stress intensity factor (SIF) solutions numerically obtained by previous research on transversely cracked cylinders (round bars) subjected to tension loading are analyzed. Surface cracks or flaws are assumed to be semi-elliptical, and solutions are compared in the matter of SIF values at the center of the crack front and at the external surface of the cylinder, so that a wide range of crack aspect ratios and relative crack depths are studied, in order to provide the engineer with solutions applicable to different real situations in fracture mechanics or damage tolerance analyses such as static or cyclic (fatigue) loading, environmentally assisted cracking or corrosion-fatigue.

Automated summary

This paper analyzes the different stress intensity factor (SIF) solutions obtained from previous research on transversely cracked cylinders (round bars) subjected to tension loading. The solutions assume semi-elliptical surface cracks or flaws, and compare SIF values at the crack front center and the external surface of the cylinder. The study covers a wide range of crack aspect ratios and relative crack depths to provide applicable solutions to various real situations in fracture mechanics or damage tolerance analyses, such as static or cyclic (fatigue) loading, environmentally-assisted cracking, or corrosion-fatigue.
