Fatigue crack growth can be a significant problem in steel structures that are subjected to a large number of repeated load cycles during their service lives. Uncertainty in fatigue behavior arises from the random nature of the service load, environmental conditions, material properties and other factors. Stochastic approaches to model this uncertainty can lead to improved fatigue-resistant design or in-service inspection and maintenance policies. This report generalizes the stochastic model of uncertainty in crack growth under constant amplitude loading by introducing a random noise process with arbitrary (generally non-Gaussian) marginal distribution and correlation structure. A computationally efficient method based on the rainflow method of stress identification is proposed for handling broad-band stress processes in analyzing stochastic crack propagation. The impact of uncertainty in flaw detection and measurement capabilities on in-service structural condition assessment and reliability-based service life prediction also is investigated. The proposed method is applied in a time-dependent reliability analysis of a steel miter gate at the Emsworth Lock and Dam that suffered severe deterioration from corrosion-fatigue. The predicted fatigue behavior is consistent with observations of damage over a sixty-year service life, providing some confirmation of the use of stochastic fatigue analysis in structural condition assessment and service life prediction.

This book demonstrates fatigue crack growth under random loading graphically. This state-of-the-art monograph introduces an expert system for crack growth predictions, particularly based on crack closure. The system is developed after years of research by the authors by using the Math-type software consisting of 5 parts. This system is unique as it is fundamentally different from previous systems as it focuses on fatigue crack growth predictions based on fatigue crack closure. This book can be a useful guide for practicing engineers, researchers, and students in the fields of mechanical, aerospace, or civil engineering.

This book offers a concise introduction to fatigue crack growth, based on practical examples. It discusses the essential concepts of fracture mechanics, fatigue crack growth under constant and variable amplitude loading and the determination of the fracture-mechanical material parameters. The book also introduces the analytical and numerical simulation of fatigue crack growth as well as crack initiation. It concludes with a detailed description of several practical case studies and some exercises. The target group includes graduate students, researchers at universities and practicing engineers.

The purpose of this Handbook is to provide a review of the knowledge and experiences in the field of fatigue fracture mechanics. It is well-known that engineering structures can fail due to cyclic loading. For instance, a cyclically time-varying loading reduces the structure strength and can provoke a fatigue failure consisting of three stages: (a) crack initiation (b) crack propagation and (c) catastrophic failure. Since last century many scientists have tried to understand the reasons for the above-mentioned failures and how to prevent them. This Handbook contains valuable contributions from leading experts within the international scientific community and covers many of the important problems associated with the fatigue phenomena in civil, mechanical and nuclear engineering.

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.
