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.
Book Synopsis On Subsurface Crack Growth in Fibre Metal Laminate Materials by :
Download or read book On Subsurface Crack Growth in Fibre Metal Laminate Materials written by and published by . This book was released on 2003 with total page 12 pages. 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.
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.

Book excerpt: Composite materials, with their higher exposure to dynamic loads, have increasingly been used in aerospace, naval, automotive, sports and other sectors over the last few decades. Dynamic Deformation, Damage and Fracture in Composite Materials and Structures reviews various aspects of dynamic deformation, damage and fracture, mostly in composite laminates and sandwich structures, in a broad range of application fields including aerospace, automotive, defense and sports engineering. As the mechanical behavior and performance of composites varies under different dynamic loading regimes and velocities, the book is divided into sections that examine the different loading regimes and velocities. Part one examine low-velocity loading and part two looks at high-velocity loading. Part three then assesses shock and blast (i.e. contactless) events and the final part focuses on impact (contact) events. As sports applications of composites are linked to a specific subset of dynamic loading regimes, these applications are reviewed in the final part. Examines dynamic deformation and fracture of composite materials Covers experimental, analytical and numerical aspects Addresses important application areas such as aerospace, automotive, wind energy and defence, with a special section on sport applications

Book Synopsis Predicting Interlaminar Fatigue Crack Growth Rates in Compressively Loaded Laminates by : AJ. Russell
Download or read book Predicting Interlaminar Fatigue Crack Growth Rates in Compressively Loaded Laminates written by AJ. Russell and published by . This book was released on 1989 with total page 17 pages. Available in PDF, EPUB and Kindle. Book excerpt: The fatigue crack growth rates of delaminations under mixed mode (I and II) loading conditions were investigated. Double cracked-lap-shear specimens were used to obtain da/dN versus ?G data for AS4/3501-6 graphite/epoxy. This, together with previously reported results for pure mode I and mode II made it possible to establish a mixed mode fatigue criterion. The validity of these findings was then tested by using them to predict the growth rates of through-the-width delaminations in laminates subject to constant amplitude compressive loadings. Symmetric honeycomb sandwich specimens with delaminations located at a depth of four, six, eight, or ten plies beneath the surface were loaded in compression at 2.5 Hz, and the fatigue crack growth rates were determined. The experimental results were generally in good agreement with the predicted behavior although fiber bridging and load-induced crack closure resulted in predicted rates being too high in some cases.

Book Synopsis Fatigue Damage Development in Notched (02/±45)s Laminates by : N. Chinatambi
Download or read book Fatigue Damage Development in Notched (02/±45)s Laminates written by N. Chinatambi and published by . This book was released on 1989 with total page 21 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study investigates delamination growth from holes in carbon fibre reinforced epoxy (CFRE) AS/3501-6 (02/±45)s laminates under tensile static and fatigue loading. Delaminations grow in a direction parallel to the loading at the 0/45 and 45/-45 interfaces. Attempts to control the location of the delamination by using inserts were unsuccessful. The delamination growth rates were fitted by a power function of the stress amplitude and mean stress. The stress amplitude is the dominant parameter. Tests were performed on dry and saturated specimens at room temperature, and there was no measurable difference in growth rates. However, block loading tests, where an overload was applied at regular intervals, resulted in growth rates five times higher than a linear sum of the individual growth rates. Compliance changes were measured and correlated with the extent of delamination. The associated matrix cracking contributes substantially to the compliance changes. The amount of matrix cracking for a given delamination length is a function of the type and level of loading. The results are interpreted in terms of the total strain energy release rate, G. Once the presence of matrix cracking is allowed for, there is reasonable agreement with results in the literature.
Book Synopsis Delamination Crack Growth in Unidirectional Fiber-Reinforced Composites Under Static and Cyclic Loading by : SS. Wang
Download or read book Delamination Crack Growth in Unidirectional Fiber-Reinforced Composites Under Static and Cyclic Loading written by SS. Wang and published by . This book was released on 1979 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: Delamination crack growth in a unidirectional composite laminate under static and fatigue loading conditions is investigated. An experimental program was performed to elucidate failure mechanisms and to characterize the growth rate of the delamination crack. Analytical modeling, based on microscopic observation, is conducted by using an advanced singular finite element method of the hybrid-stress model formulated through the minimum complementary energy principle. Solutions obtained from the analysis probe the fundamental nature of the problem. Implications of the results on the applicability of the classical laminate theory are discussed. Using a mixed-mode failure criterion, the delamination growth under a monotonically increasing load may be predicted satisfactorily. The rate of delamination crack propagation under fatigue loading is found to be related directly to the amplitudes of cyclic opening and shearing mode stress intensity factors by a power law relationship. The study elucidates many salient features of the problem, provides insight to the basic nature of the delamination failure behavior, and should be of practical importance in the design and testing of composite materials.
