Reseña del editor:

Fatigue failure is a multi-stage process. It begins with the initiation of cracks, and with continued cyclic loading the cracks propagate, finally leading to the rupture of a component or specimen. The demarcation between the above stages is not well-defined. Depending upon the scale of interest, the variation may span three orders of magnitude. For example, to a material scientist an initiated crack may be of the order of a micron, whereas for an engineer it can be of the order of a millimetre. It is not surprising therefore to see that investigation of the fatigue process has followed different paths depending upon the scale of phenomenon under investigation. Interest in the study of fatigue failure increased with the advent of industrial­ ization. Because of the urgent need to design against fatigue failure, early investiga­ tors focused on prototype testing and proposed failure criteria similar to design formulae. Thus, a methodology developed whereby the fatigue theories were proposed based on experimental observations, albeit at times with limited scope. This type of phenomenological approach progressed rapidly during the past four decades as closed-loop testing machines became available.

Reseña del editor:

This book provides a unified approach to the fatigue damage evaluation of smooth, notched and cracked components. The mechanics of cyclic deformation behaviour, crack initiation and crack propagation are discussed from both microscopic and macroscopic viewpoints, and a comprehensive treatment of multiaxial fatigue loading is included. All aspects of the mechanics of crack growth - short cracks, long cracks and cracks initiated from notches - are discussed in a unified manner. Explicit relationships are given by which fatigue life can be predicted based on limited material data, as well as a master curve (a unique curve) which combines uniaxial and multiaxial loadings. This is of significant importance in practical applications. Fatigue Damage, Crack Growth and Life Prediction is designed to serve as an in-depth introduction and a useful reference for materials scientists and mechanical, design, aeronautical, and civil engineers who are either studying or require information about fatigue behaviour and crack growth in engineering components.
