Investigation of fracture behaviour of asymmetric spur gear
TL;DR: In this article, a parametric analysis was carried out for asymmetric spur gears to examine the fracture behavior under mixed-mode fracture condition and explore the significance of each gear parameters.
Journal ArticleDOI
Constant-amplitude fatigue behavior of M24 high-strength bolt of end-plate flange connection
TL;DR: In this article, an axial-tensile fatigue test under a stress ratio of 0.5 was performed on 21 specimens of high-strength bolts to investigate the constant-amplitude fatigue performance of grade 8.8 M24 high strength bolts.

Analysis Of Fracture Characteristics Of Thin And Thick Rim Asymmetric Spur Gear Based On Strain Energy Release Rate
TL;DR: In this article , the effect of backup ratio on the fatigue crack behavior of asymmetric and asymmetric spur gear under mix mode fracture is investigated, and the authors give valuable guidelines for designing asymmetric spars gears to reduce the weight without compromising the service life.

Elastic-plastic Fracture Analysis of External Thread of Drive Shaft Shell of a Positive Displacement Motor
Guanghui Zhao,Guipeng Liao +1 more
TL;DR: In this paper, the elastic-plastic fracture performance of the threaded connection is simulated under both make-up torque and bending moment, and explicit relationships between characteristic J-integrals and the crack depth are obtained for the DSS.

Stress-intensity factors for a wide range of semi-elliptical surface cracks in finite-thickness plates
Ivatury S. Raju,James C. Newman +1 more
TL;DR: In this article, the authors presented the stress-intensity factors for shallow and deep semi-elliptical surface cracks in plates subjected to tension and verified the accuracy of the three-dimensional finite-element models employed.
Journal ArticleDOI
Shape change of surface cracks in round bars under cyclic axial loading
TL;DR: In this paper, an elliptical-arc surface crack in a round bar under cyclic axial loading with constant amplitude is considered, and the stress-intensity factor along the crack front is calculated through a finite-element analysis by employing isoparametric solid elements.
Journal ArticleDOI
The Distribution of Load in Screw Threads
TL;DR: In this paper, it was shown that the load distribution along the length of a nut is not uniform owing to the strains set up in the bolt and nut under load, and that the maximum intensity of loading occurs at the bearing face of the nut, and may be from two to four or more times the mean, depending on the thread form, the proportions of the members, and the degree of lubrication.
Journal ArticleDOI
Simplified model for the fatigue growth analysis of surface cracks in round bars under mode I
N. Couroneau,J. Royer +1 more
TL;DR: In this paper, the fatigue growth of an edge flaw in a round bar under cyclic tension or bending loading is examined, using a two-parameter numerical model, and it is shown that the crack front evolution is defined by a very small number of parameters, which varies during crack growth.

Generalized stress intensity factors of V-shaped notch in a round bar under torsion, tension, and bending
Nao-Aki Noda,Yasushi Takase +1 more
TL;DR: In this article, generalized stress intensity factors for a V-shaped notched round bar under tension, bending, and torsion were calculated using the singular integral equation of the body force method.
