The application of fracture mechanics to mechanical fasteners requires stress-intensity-factor solutions for cracks at fastener holes and in threaded, round bars. This bibliography lists references that present stress-intensity-factor solutions for cracks at circular holes and a wide range of cylindrical, solid and hollow, round bars, unnotched, and circumferentially notched, subjected to axial loads, bending. Notched cases include shoulder fillets, multiple thread-like circumferential projections, and thread-like single circumferential grooves in round bars. In these cases, the projections and grooves were not helical. Instead, the planes of the projections and grooves were perpendicular to the axis of the round bar. The geometries of cracks in round bars include circumferential cracks and cracks initiated at a point on the surface of the cylinder. The latter crack geometries include straight, curved, semicircular, semi-elliptical, and sickle-shaped crack fronts. A few references treat high-strength bolts.
