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: A two-component crack growth model has been developed to treat fatigue crack growth under constant and variable amplitude loading. The model is based on a concept introduced by Paris which relates the crack growth to the instantaneous plastic zone size ahead of the crack-tip. This concept was applied to describe crack growth in the presence of cyclic and primary plastic flow. The model was formulated on an incremental basis in which a particular component of the model is integrated about a discrete portion of the load excursion. The model includes the effects of cyclic and monotonic crack growths and crack closure. The results for fatigue crack growth data reported in the literature for multiple overload and severe flight sequences are compared with the model predictions. The model was shown to describe accelerated crack growth behavior typically observed during these sequences. Acceleration effects occur in the presence of primary plastic flow which is related to the ductile tearing mechanism and is not dependent upon crack closure or other load-history effects. Moreover, the model describes the phenomenological variation of the acceleration effects over such sequences. The predicted crack growth agrees well with the experimental data.

Available in PDF, EPUB and Kindle. Book excerpt: The book summarizes recent international research and experimental developments regarding fatigue crack growth investigations of rubber materials. It shows the progress in fundamental as well as advanced research of fracture investigation of rubber material under fatigue loading conditions, especially from the experimental point of view. However, some chapters will describe the progress in numerical modeling and physical description of fracture mechanics and cavitation phenomena in rubbers. Initiation and propagation of cracks in rubber materials are dominant phenomena which determine the lifetime of these soft rubber materials and, as a consequence, the lifetime of the corresponding final rubber parts in various fields of application. Recently, these phenomena became of great scientific interest due to the development of new experimental methods, concepts and models. Furthermore, crack phenomena have an extraordinary impact on rubber wear and abrasion of automotive tires; and understanding of crack initiation and growth in rubbers will help to support the growthing number of activities and worldwide efforts of reduction of tire wear losses and abrasion based emissions.

Download or read book The Development of an Analytical Prediction Technique for Variable Amplitude Fatigue Crack Propagation written by M. F. Kanninen and published by . This book was released on 1977 with total page 110 pages. Available in PDF, EPUB and Kindle. Book excerpt: The development of a fatigue crack-growth predictive technique for variable amplitude loading, initiated under previous NADC support, was continued. Attention was focused on a simple version of the general model. This provided a crack growth predictive formula for constant amplitude loading. Comparisons with experimental results and a semiempirical crack-growth law ahow that the prediction is quite realistic. The work has also indicated how improvements in the general model can be made to cope with more realistic service conditions. The further steps required to develop an efficient model that can cope with both variable amplitude loading and environmental effects are outlined. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: Considerable data on fatigue properties of materials under constant amplitude loading is available in the literature under the forms representative of the different aspects of the fatigue phenomenon. To employ these data, the design engineer must adapt it to the particular service conditions that he is concerned with. The stress vs. life or S-N curve is largely related to the fatigue initiation behaviour of materials and defines the endurance limit which is used for design. The strain-life curve is of more recent origin and relates the elastic and plastic strain amplitudes to the initiation life. Fatigue propagation data are presented on a crack growth rate vs. stress intensity factor range diagram.

Download or read book Prediction of Crack Growth Under Variable-Amplitude and Spectrum Loading in a Titanium Alloy written by EP. Phillips and published by . This book was released on 2004 with total page 19 pages. Available in PDF, EPUB and Kindle. Book excerpt: The present paper is concerned with the application of a plasticity-induced crack-closure model, FASTRAN, to predict fatigue-crack growth under various load histories in a thin-sheet Ti-62222 STA titanium alloy. This alloy was a leading candidate for a metallic High-Speed-Civil-Transport (HSCT) aircraft in the United States. The crack-growth model was based on the Dugdale strip-yield model but modified to leave plastically deformed material in the wake of the advancing crack. The model includes the influence of "constraint" on the development of plasticity and closure during constant- and variable-amplitude load histories. The model was used to correlate crack-growth-rate data under constant-amplitude loading over a wide range in crack-growth rates and stress ratios at two service temperatures (room temperature and 175°C). Tests on repeated spike overloads were used to help establish the constraint variations in the model. The model was then used to predict crack growth under two simulated aircraft spectrum load histories at the two temperatures. The spectra were a commercial HSCT wing spectrum and the Mini-TWIST (transport wing spectrum). This paper will demonstrate how constraint plays a leading role in the retardation and acceleration effects that occur under variable- amplitude and spectrum loading. The model was able to calculate the effects of repeated spike overloads on crack growth at the two temperatures, generally within about ± 30 %. Also, the predicted crack-growth behavior under the HSCT spectrum agreed well with test data (within 30 %). However, the model under-predicted the fatigue-crack-growth behavior under the Mini-TWIST spectrum by about a factor-of-two. Some of the differences may be due to fretting-product-debris-induced closure or three-dimensional effects, such as free-surface closure, not included in the model. Further study is needed on life predictions under the Mini-TWIST flight spectrum.
