Available in PDF, EPUB and Kindle. Book excerpt: Accounting for fatigue loadings has been a concern ever since the widespread introduction of metallic materials into load-bearing components in the nineteenth century. Calculations were developed based on the analysis capabilities of their time incorporating all the latest technologies of their era. At the time, that technology was pencil-and-paper calculations. Today's calculations are computer-based. The widespread use of computing methods has greatly enhanced the analyst abilities for simulating internal stress and strain fields. Unfortunately, current fatigue analyses often force-fit current stress field calculations into fatigue analysis methods meant for nineteenth century stress calculation methods. It's never a good idea to force methods optimized for pre-computer calculations to work with computers. This text presents a more integrated approach to computer-based fatigue analysis methods. Like what was originally done, the latest technologies are applied rather than force-fitting computer computational capabilities into nineteenth-century techniques. Holistic approaches incorporating all knowledge have long been established as the most successful approach to problem-solving. Incorporating all knowledge with the most modern capabilities is the preferred approach. Holistic methods strive to reduce subjective inputs and replace them with consistent objective ones. This text aims to transition disjointed inefficient analyses into a unified computer-based holistic technique by introducing a fatigue analysis method specifically developed for computer simulations. Ultimately, for any method or theory to be valuable, it must be put into practice and prove itself. That entails leadership decision-making. Engineering design development activities will lead to final decisions. Information in a holistic approach must include the reliability of the information. How consistent are the predictions? Are the two types of potential scatter, analytic, and physical properly addressed? Is analytic scatter minimized while maintaining creativity? Is physical scatter totally understood? Effective program management requires knowledge on both types of scatter and, most importantly, the ability to realize the difference. A novel computer-based unified approach to fatigue methods is presented which incorporates a holistic approach for more accurate and consistent analyses, including the management and leadership of fatigue analysis projects, minimization of analytic scatter, management of physical scatter, and unification of methods that minimize subjective inputs often needed to bridge inconsistent techniques.

Available in PDF, EPUB and Kindle. Book excerpt: Seminar paper from the year 2015 in the subject Engineering - Aerospace Technology, , course: Aeronautical Engineering, language: English, abstract: The fatigue life is essential for every aircraft to rectify several damages occurred on it. In this project we have done fatigue analysis of the aircraft wing Boeing 737 series wing. The detailed modeling of aircraft wing structure made by using the software CREO parametric 2.0. The stress analysis of the wing structure is carried out. The stresses are estimated by using the finite element approach with the help of NX-NASTRON to find out the fatigue life and safety factor of the structure. This Project describes about the finite element analysis of spar, ribs of a wing. The objective of this study is to reduce the weight to the maximum possible extent. The response of the wing structure will be evaluated. In this study prediction of fatigue life, safety factor, strength safety factor will be carried out.

Book excerpt: Aircraft Fatigue: Design, Operational and Economic Aspects contains the proceedings of the ""Symposium on Aircraft Fatigue—Design, Operational and Economic Aspects,"" held in Melbourne, Australia, on May 22-24, 1967. The papers explore the design and operational aspects of the fatigue problem in general aviation and transport aircraft, as well as the economic aspects of the fatigue problem as it affects both operators and manufacturers. This book is comprised of 21 chapters and begins with a description of an approach to structural reliability analysis based on order statistics and the expected time to first failure in a fleet of specified magnitude, along with its application to structures subject to progressive fatigue damage. The following chapters deal with structural load measurement and analysis; design and certification programs for a wide range of aircraft types including the Anglo-French and American civil supersonic transports; acoustic fatigue; and the design of joints. The detection of fatigue cracks in service and the effects of fatigue on the cost of design and operation of aircraft are also discussed. This monograph will be a useful resource for aircraft and aeronautical engineers as well as officials of civil aviation.

Book Synopsis Fatigue of Structures and Materials by : J. Schijve
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.
