Download or read book Fatigue of Structures and Materials written by J. Schijve and published by Springer Science & Business Media. This book was released on 2008-12-16 with total page 627 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fatigue of structures and materials covers a wide scope of different topics. The purpose of the present book is to explain these topics, to indicate how they can be analyzed, and how this can contribute to the designing of fatigue resistant structures and to prevent structural fatigue problems in service. Chapter 1 gives a general survey of the topic with brief comments on the signi?cance of the aspects involved. This serves as a kind of a program for the following chapters. The central issues in this book are predictions of fatigue properties and designing against fatigue. These objectives cannot be realized without a physical and mechanical understanding of all relevant conditions. In Chapter 2 the book starts with basic concepts of what happens in the material of a structure under cyclic loads. It illustrates the large number of variables which can affect fatigue properties and it provides the essential background knowledge for subsequent chapters. Different subjects are presented in the following main parts: • Basic chapters on fatigue properties and predictions (Chapters 2–8) • Load spectra and fatigue under variable-amplitude loading (Chapters 9–11) • Fatigue tests and scatter (Chapters 12 and 13) • Special fatigue conditions (Chapters 14–17) • Fatigue of joints and structures (Chapters 18–20) • Fiber-metal laminates (Chapter 21) Each chapter presents a discussion of a speci?c subject.

Available in PDF, EPUB and Kindle. Book excerpt: The importance of delay (or, retardation in the rate of fatigue crack growth) produced by load interactions in variable-amplitude loading on the accurate prediction of fatigue lives of aircraft and other engineering structures has been recognized for some time and has begun to receive greater attention in recent years. Recent investigations showed that the effects of delay can be quite large, and that these effects need to be taken into account in developing improved fatigue analysis procedures for aircraft and other engineering structures. A number of models (based on the concepts of crack closure, residual stress intensity factor, etc.) have been proposed to account for the effects of delay. These models, while successfully predicting trends in the rate of fatigue crack growth for randomized load spectra, appear to break down for ordered spectra. Several basic problems contributed to the lack of complete success, and needs to be resolved in the development of improved models for predicting load interaction effects (chiefly delay) on fatigue crack growth.

Available in PDF, EPUB and Kindle. Book excerpt: The reduced crack growth rate caused by each high-low load sequence of a complex load spectrum is modeled by a modified empirical constant-amplitude crack propagation relationship. The modification consists of the replacement of the crack rate term by a fractional derivative. The order of the derivative is a nondimensional parameter which is defined in terms of each high-low load sequence occurring in the spectrum. A cycle-by-cycle solution of the fractional differential equation yields the crack growth behavior for the spectrum. The approach is evaluated by comparing predictions with available experimental results for three aluminum alloys (7075-T6, 7050-T73, 2024-T3), two titanium alloys (Ti-6A1-4V, Ti-6Al-2Sn-4Zr-6Mo) and a nickel base superalloy IN-100. In all cases the method accurately predicted the general trends and estimates were well within a factor of two for 39 out of 40 tests analyzed.

This book was released on 1982 with total page 23 pages. Available in PDF, EPUB and Kindle. Book excerpt: The present paper is concerned with the application of an analytical crack-closure model in the study of crack growth under various load histories. The model was based on a concept like the Dugdale model, but modified to leave plastically deformed material in the wake of the advancing crack tip.
