Download or read book Stability of Filament Wound Cylinders Under Combined Loading written by A. Holston (Jr.) and published by . This book was released on 1967 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: A combined analytical and experimental investigation of the stability of composite cylindrical shells is presented. Forty-five fiber-glass filament wound cylinders were fabricated, buckled, and analyzed. The number 45 stems from considering three diameters (6 in, 12 in, 24 in), three filament configurations, and five loadings. All cylinders had essentially the same wall thickness, .035 in, and each cylinder length was nearly equal to its diameter. The five loadings were: (1) uniform axial compression, (2) torsion, (3) bending, (4)combined torsion and uniform axial compression, (5) combined bending and uniform axial compression. The analysis was based on linear anisotropic shell theory and the effects of boundary conditions were not considered. Preliminary tests were conducted to determine the in-plane stiffnesses and individual layer elastic properties. The experimental buckling loads were from 67 to 90% of predicted values for loading without torsion. The bending buckling stress was, for all practical purposes, equal to the axial buckling stress and the combined bending with uniform axial load interaction was essentially linear. The experimental torsion buckling loads were greater than the predicted values but the boundary conditions were not considered in the analysis. Buckling loads were computed for boron filament wound cylinders of the same size and winding configurations. These computations show that the buckling loads of boron and aluminum cylinders, of the same size, are nearly equal. A similar comparison on a weight basis would produce the same result since their densities are essentially equal.

Available in PDF, EPUB and Kindle. Book excerpt: & Quot;The unifying treatment of structural design presented here should prove useful to any engineer involved in the design of structures. A crucial divide to be bridged is that between applied mechanics and materials science. The onset of specialization and the rapid rise of technology, however, have created separate disciplines concerned with the deformation of solid materials. Unfortunately, the result is in many cases that society loses out on having at their service efficient, high-performance material/structural systems. & quot. & quot;We follow in this text a very methodological process to introduce mechanics, materials, and design issues in a manner called total structural design. The idea is to seek a solution in & quot;total design space. & quot; & quot. & quot;The material presented in this text is suitable for a first course that encompasses both the traditional mechanics of materials and properties of materials courses. The text is also appropriate for a second course in mechanics of materials or a follow-on course in design of structures, taken after the typical introductory mechanics and properties courses. This text can be adapted to several different curriculum formats, whether traditional or modern. Instructors using the text for a traditional course may find that the text in fact facilitates transforming their course over time to a more modern, integrated approach. & quot;--BOOK JACKET.

Download or read book Concrete Structures Subjected to Impact and Blast Loadings and Their Combinations written by Chunwei Zhang and published by CRC Press. This book was released on 2022-05-08 with total page 335 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although much research focuses on investigating the responses of reinforced concrete (RC) structures under sole impact or blast loads, the responses of RC structures under a combination of impact and blast loads currently represent a gap in our knowledge. The combined actions of impact and blast loadings may be applied to RC structures during accidental or intentional collision of vessels, vehicles, etc., carrying explosive materials. A comprehensive study on the vulnerability of various structural members is carried out using finite element (FE) simulations under combination of impact and blast loads with the variations of various loading- and structural-related parameters and key parameters. This book introduces various structural analysis approaches for concrete structures when subjected to extreme loads such as impact and blast loadings. The theory of the combinations of impact and blast loads is proposed that can provide primary insights to the specific readers to develop new ideas in impact and blast engineering, including combined actions of extreme loads arising from real-world intentional or accidental events. This book will be of value to students (undergraduate or postgraduate), engineers, and researchers in structural and civil engineering, and specifically, those who are studying and investigating the performances of concrete structures under extreme loads.

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.

Download or read book Fatigue Design written by Eliahu Zahavi and published by CRC Press. This book was released on 2019-01-22 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: Modern analytical theories of fatigue coupled with a knowledge of processing effects on metals make up the sound basis for designing machine parts that are free from unexpected failure. Fatigue Design: Life Expectancy of Machine Parts provides the information and the tools needed for optimal design. It highlights practical approaches for effectively solving fatigue problems, including minimizing the risk of hidden perils that may arise during production processes or from exposure to the environment.The material is presented with a dual approach: the excellent coverage of the theoretical aspects is accented by practical illustrations of the behavior of machine parts. The theoretical approach combines the fundamentals of solid mechanics, fatigue analysis, and crack propagation. The chapters covering fatigue theories are given special emphasis, starting with the basics and progressing to complicated multiaxial nonlinear problems.The practical approach concentrates on the effects of surface processing on fatigue life and it illustrates many faceted fatigue problems taken from case studies. The solutions demonstrate the authors' detailed analyses of failure and are intended to be used as preventive guidelines. The cases are a unique feature of the book. The numerical method used is the finite element method, and is presented with clear explanations and illustrations.Fatigue Design: Life Expectancy of Machine Parts is an extremely valuable tool for both practicing design engineers and engineering students.
