Reseña del editor:

Failures of many mechanical components in service result from fatigue. The cracks which grow may either originate from some pre-existing macroscopic defect, or, if the component is of high integrity but highly stressed, a region of localized stress concentration. In turn, such concentrators may be caused by some minute defect, such as a tiny inclusion, or inadvertent machining damage. Another source of surface damage which may exist between notionally 'bonded' components is associated with minute relative motion along the interface, brought about usually be cyclic tangential loading. Such fretting damage is quite insidious, and may lead to many kinds of problems such as wear, but it is its influence on the promotion of embryo cracks with which we are concerned here. When the presence of fretting is associated with decreased fatigue performance the effect is known as fretting fatigue. Fretting fatigue is a subject drawing equally on materials science and applied mechanics, but it is the intention in this book to concentrate attention entirely on the latter aspects, in a search for the quantification of the influence of fretting on both crack nucleation and propagation. There have been very few previous texts in this area, and the present volume seeks to cover five principal areas; (a) The modelling of contact problems including partial slip under tangentialloading, which produces the surface damage. (b) The modelling of short cracks by rigorous methods which deal effectively with steep stress gradients, kinking and closure. (c) The experimental simulation of fretting fatigue.

Reseña del editor:

The field of fretting fatigue is extremely important in many areas of mechanical engineering. Fatigue cracks frequently initiate not from free surfaces, but from clamped or bolted components suffering vibration or other forms of minor oscillatory loading. This produces surface degradation, and conditions ripe for the initiation and early propulsion of cracks, constituting the phenomenon of fretting fatigue.
This volume presents a summary of the current state of knowledge of fretting fatigue, with particular reference to the influence of mechanical variables, such as the applied forces, coefficient of friction, and surface finish. The book includes elements of the theories of contact mechanics and fracture mechanics in order to establish a rigorous framework for the understanding of the phenomenon. It goes on to describe fretting fatigue experiments and to describe the influence of the variables cited on fretting fatigue performances. The treatment is largely independent of the materials studied.
The book does not require specialised mathematical knowledge.
For mechanical engineers and materials scientists in research and development. This volume can also be recommended as a supplementary text for graduate students.
