Mechanisms of fatigue-crack propagation in ductile and brittle solids
TL;DR: In this article, the authors examined the mechanisms of fatigue-crack propagation with particular emphasis on the similarities and differences between cyclic crack growth in ductile materials such as metals, and corresponding behavior in brittle materials, such as intermetallics and ceramics.
Journal ArticleDOI
Structural and functional fatigue of NiTi shape memory alloys
TL;DR: In this paper, structural and functional fatigue of NiTi shape memory alloys is investigated and four cases of fatigue are discussed: (1) the evolution of the stress-strain hysteresis in low cycle pull-pull fatigue of pseudo-elastic NiTi wires.
Journal ArticleDOI
Dislocation behavior in fatigue
TL;DR: In this article, the authors apply recent advances in understanding mechanisms of unidirectional deformation to fatigue and propose reinterpretations or new mechanisms for the following: the formation of dislocation veins and of persistent slip bands (PSB's), the behavior of dislocations in established PSB's, and the transformation of PSB dipolar walls into dislocation cells.

TL;DR: In this paper, an approach has been developed on the metastable beta titanium alloy Ti 21S that allows for visualization and analysis of the growth rate and crystallographic orientation of the fracture surface.

Fracture of Solids
TL;DR: The role of microscopic cracks and the departure of actual strength from theoretical values are discussed in this paper, where the type of fraction produced by various forms of stress, the dependence on the nature of the stress, and the rate of application are described.

On fatigue crack propagation in F.C.C. metals
A.J McEvily,R.G Boettner +1 more
TL;DR: Crack growth in single crystals of aluminum, polycrystalline copper and a series of polycrystaline copper alloys was investigated to study the mechanisms of growth and the influence of stacking fault energy on the manner and rate of growth.
Journal ArticleDOI
A theory of the origin of fatigue cracks
TL;DR: In this paper, a model based on the concept of cross slip is given to explain how a slip band can develop into a crack if dislocations in the band are free to move backwards and forwards.

Dislocations and persistent slip bands in fatigued copper
E. E. Laufer,W. N. Roberts +1 more
TL;DR: In this paper, the dislocation structure below persistent slip bands is found to consist of rows of elongated cells within a region extending at least 170 microns below the specimen surface, indicating that slip occurs in at least two directions in the primary plane.
