Available in PDF, EPUB and Kindle. Book excerpt: This book contributes to the field of hybrid technology, describing the current state of knowledge concerning the hybrid material concept of laminated metallic and composite sheets for primary aeronautical structural applications. It is the only book to date on fatigue and fracture of fibre metal laminates (FMLs). The first section of the book provides a general background of the FML technology, highlighting the major FML types developed and studied over the past decades in conjunction with an overview of industrial developments based on filed patents. In turn, the second section discusses the mechanical response to quasi-static loading, together with the fracture phenomena during quasi-static and cyclic loading. To consider the durability aspects related to strength justification and certification of primary aircraft structures, the third section discusses thermal aspects related to FMLs and their mechanical response to various environmental and acoustic conditions.

Available in PDF, EPUB and Kindle. Book excerpt: Fibre metal laminates were developed at Delft University of Technology in The Netherlands, from the beginning of the 1980s. This is a new family of hybrid materials consisting of thin metal layers bonded together by fibres embedded in an adhesive. As a result of this build-up, fibre metal laminates possess a mixture of the characteristics of both metals and composite materials. Initial development led to the `Arall' variant using aramid fibres, which was first applied on the C-17 military transport aircraft around 1990. Large-scale application became possible with a variant using glass fibres, dubbed `Glare', which was selected for the Airbus A380 super jumbo in 2001. This is the first book to discuss these new materials and it deals mostly with Glare. It covers most of the relevant aspects of the materials, from static mechanical properties, fatigue and impact to design, production and maintenance of aircraft structures. This book contains the basic information on these new materials necessary for engineers and aircraft operators alike.

Available in PDF, EPUB and Kindle. Book excerpt: Fatigue crack growth in fibre metal laminates (FMLs) is significantly more complex than in monolithic materials due to the interaction of various physical mechanisms that govern the growth of cracks in laminates. Extensive research has gone into the development of analytical models that try to predict the growth of surface and through-cracks in the FML Glare under fatigue loading. To date, less emphasis has been placed on developing fatigue crack growth models for part through cracks. These part through cracks exhibit different rates of growth for each layer of the laminate based upon differing stress levels and delamination zone sizes. To better predict the residual strength of FML structures, understanding the behavior of subsurface crack growth is required. For this reason, data of crack growth rates for layers of various laminates were compared to an analytical fatigue crack growth model developed for surface cracks in a specific type of FML, Glare. This paper gives an initial assessment of the model's veracity for subsurface crack growth.

This book was released on 2005 with total page 356 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aluminum fiber metal laminates (AFMLs) are a promising new type of fiber metal laminate that consists of aluminum foils interleaved with layers of a graphite fiber-polymer matrix composite (PMC) material. AFMLs combine the attractive features of aluminum with the advantages of traditional graphite polymer-matrix composite. There are a number of anticipated benefits of such a material including weight reduction, improved bearing capability and high conductivity for lightning strike protection. The presence of the fiber-reinforced composite also provides a method to arrest cracks in the aluminum layers via fiber bridging. In order to understand crack initiation and growth in AFML specimens, this study considers the tensions-tension fatigue response of 39 AFML specimens at five different stress levels and three different specimen configurations. The specimens and support for the project was provided by The Boeing Company (Structures Damage and Technology Group). Several methods of crack investigation were considered for this study; it was determined that visual inspection through digital photography at evenly spaced intervals throughout the test provided the best method for the characterization of crack initiation and growth. Visual analysis of the specimen images was performed. This led to precise estimates of the cycles to crack initiation as well as crack length versus cycle count throughout each experiment. The results clearly demonstrated reduced crack growth rates throughout each experiment, which is likely attributed to fiber bridging. Crack growth versus cycles for various experiments were well represented by a single reference curve with appropriate cycle count scale factors. This demonstrates that linear elastic fracture mechanics appears to govern the crack growth response. This project demonstrates the value of visual imaging to monitor crack initiation and growth in AFMLs and offers a potential method to better understanding the phenomenon in future studies.

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: An overview of the virtual crack closure technique is presented. The approach used is discussed, the history summarized, and insight into its applications provided. Equations for two-dimensional quadrilateral elements with linear and quadratic shape functions are given. Formula for applying the technique in conjuction with three-dimensional solid elements as well as plate/shell elements are also provided. Necessary modifications for the use of the method with geometrically nonlinear finite element analysis and corrections required for elements at the crack tip with different lengths and widths are discussed. The problems associated with cracks or delaminations propagating between different materials are mentioned briefly, as well as a strategy to minimize these problems. Due to an increased interest in using a fracture mechanics based approach to assess the damage tolerance of composite structures in the design phase and during certification, the engineering problems selected as examples and given as references focus on the application of the technique to components made of composite materials.
