A further study on fatigue crack initiation life — mechanical model for fatigue crack initiation

International Journal of Fatigue, 1986
Abstract In the present study, a new formula for the fatigue crack initation life is developed based on recent progress in the study of fatigue damage and crack initiation, and is substantiated experimentally. The new formula reveals a correlation between the fatigue crack initiation life, the notched element geometry, the cyclic loading condition ...

The physics of fatigue crack initiation

International Journal of Fatigue, 2013
Abstract The fatigue life of a component can be expressed as the sum of two segments of life: (a) the number of loading cycles required to initiate a crack and (b) the number of cycles it takes that crack to propagate to failure. In this review, the primary emphasis is relating the fatigue crack initiation to the microstructure of the material.

On Crack Initiation Mechanisms in Fretting Fatigue

Journal of Applied Mechanics, 2000
By using the crack analogue model of rigid flat-ended contact, crack initiation in fretting fatigue is analyzed. The coefficient of friction at the edge of contact, which characterizes the asymptotic stress field, is considered as the primary controlling parameter in the process.

A Dislocation Model for Fatigue Crack Initiation

Journal of Applied Mechanics, 1981
The slip band formed in a grain on the material surface is a preferential site for crack initiation during low strain fatigue of polycrystalline metals. The forward and reverse plastic flow within the slip band is modeled in the present study by dislocations with different signs moving on two closely located layers, and it is assumed that their ...

The initial fatigue crack

Proceedings of the Royal Society of London. Series A. Mathematical and Physical Sciences, 1957
Abstract A discussion is given of the formation of persistent slip bands during cyclic stressing and their development into fatigue cracks. In copper and in aluminium at low temperatures fatigue cracks appear to be formed in this way; at room temperature in aluminium they may form also along grain boundaries.

Fatigue Crack Initiation with Creep

1982
Experimental observations of the micromechanics theory of fatigue crack initiation of Lin and Ito are reviewed. This theory is shown to be applicable also for time-dependent fatigue. An aluminum polycrystal subject to cyclic tension and compression is considered.
