TLDR
In this paper, the authors determined dimensionless stress-intensity factors for single-edge-cracks solid and hollow round bars loaded in bending, and calculated the factors from experimental compliance (inverse slope of load-displacement curve) measurements.Abstract:
Dimensionless stress-intensity factors were determined for single-edge-crack solid and hollow round bars loaded in bending These factors were calculated from experimental compliance (inverse slope of load-displacement curve) measurements made on round bars loaded in three-point bending The compliance specimens had span to diameter ratios of 667 and 333, and measurements were made over a range of dimensionless crack lengths from 0002 to 070 The tests were made using 3-in (76-mm) and 6-in (152-mm) solid and hollow round bars notched on one side; the hollow bars had an inner to outer diameter ratio of 033 A comparison was made with data in the literature for rectangular bars; for ana/D of 00001, the dimensionless stress-intensity factor for a solid round bar is 13 vs 20 for a rectangular barread more

Elliptical‐arc surface cracks in round bars
TL;DR: In this paper, the crack aspect ratio influence on the stress-intensity factor of elliptical-arc edge flaws in solid round bars under tension or bending loading is discussed. And the relative crack depth between the depth a of the crack's deepest point and the bar diameter D ranges from 0.1 to 0.6.

Fracture strength for a high strength steel bridge cable wire with a surface crack
TL;DR: In this article, the fracture strength of a cracked suspension bridge wire is determined based on linear elastic fracture mechanics (LEFM), and failure analysis is performed based on both the fracture toughness criterion and the net section theory.

Residual Stresses in Patch Welded Circular Plates : A Theoretical Study of Residual Welding Stresses and Deformations (Report 3)
TL;DR: In this article, the residual welding stresses in a patch welded circular plate are obtained as the inherent stresses caused by the inherent strain, and the results of axially symmetric inherent stresses presented in the first report can be applied in this case.
