Journal ArticleDOI
TL;DR: In this paper, a computational model for the determination of service life of gears with regard to bending fatigue in a gear tooth root is presented, where the fatigue process leading to tooth breakage is divided into crack initiation (Ni) and crack propagation (Np) periods.

Journal ArticleDOI
TL;DR: In this paper, a model of fatigue crack growth based on an analysis of elastic/plastic stress and strain at the crack tip is presented and the number of cycles required for material failure inside the highly strained zone is calculated.

Journal ArticleDOI
TL;DR: In this article, the authors investigated the fatigue crack growth behavior resulting from single and multiple applications of overload for HT80 steel and found that a peak load was found to cause retardation of the crack growth rate, which becomes stronger with increasing the peak/baseline stress ratio or with decreasing baseline stress intensity.

ReportDOI
TL;DR: In this article, the authors proposed a bond damage model within peridynamics to treat the nucleation and growth of cracks due to cyclic loading, which is an extension of traditional solid mechanics in which the field equations can be applied on discontinuities such as growing cracks.
Abstract: The peridynamic theory is an extension of traditional solid mechanics in which the field equations can be applied on discontinuities, such as growing cracks. This paper proposes a bond damage model within peridynamics to treat the nucleation and growth of cracks due to cyclic loading. Bond damage occurs according to the evolution of a variable called the %22remaining life%22 of each bond that changes over time according to the cyclic strain in the bond. It is shown that the model reproduces the main features of S-N data for typical materials and also reproduces the Paris law for fatigue crack growth. Extensions of the model account for the effects of loading spectrum, fatigue limit, and variable load ratio. A three-dimensional example illustrates the nucleation and growth of a helical fatigue crack in the torsion of an aluminum alloy rod.

Journal ArticleDOI
TL;DR: In this article, the authors performed a post experimental examination of the fracture surfaces revealed that a striation forming mechanism was not active at short cracks, but as crack length increased, the occurrence of striations increased in the interior of the specimen.
