Hybrid Finite Element Method for Stress Analysis of Laminated Composites by Suong Van Hoa,Wei Feng Pdf

This book has one single purpose: to present the development of the partial hybrid finite element method for the stress analysis of laminated composite structures. The reason for this presentation is because the authors believe that partial hybrid finite element method is more efficient that the displacement based finite element method for the stress analysis oflaminated composites. In fact, the examples in chapter 5 of this book show that the partial hybrid finite element method is about 5 times more efficient than the displacement based finite element method. Since there is a great need for accurate and efficient calculation of interlaminar stresses for the design using composites, the partial hybrid finite method does provide one possible solution. Hybrid finite method has been in existence since 1964 and a significant amount of work has been done on the topic. However, the authors are not aware of any systematic piece of literature that gives a detailed presentation of the method. Chapters of the displacement finite element method and the evolution 1 and 2 present a sununary of the hybrid finite element method. Hopefully, these two chapters can provide the readers with an appreciation for the difference between the displacement finite element method and the hybrid finite element. It also should prepare the readers for the introduction of partial hybrid finite element method presented in chapter 3.

Mechanics and Analysis of Composite Materials by Valery V. Vasiliev,Evgeny V. Morozov Pdf

This book is concerned with the topical problems of mechanics of advanced composite materials whose mechanical properties are controlled by high-strength and high-stiffness continuous fibers embedded in polymeric, metal, or ceramic matrix. Although the idea of combining two or more components to produce materials with controlled properties has been known and used from time immemorial, modern composites were only developed several decades ago and have now found intensive application in different fields of engineering, particularly in aerospace structures for which high strength-to-weight and stiffness-to-weight ratios are required. There already exist numerous publications that cover anisotropic elasticity, mechanics of composite materials, design, analysis, fabrication, and application of composite structures but the difference between this book and the existing ones is that this is of a more specific nature. It covers specific features of material behaviour such as nonlinear elasticity, plasticity, creep, and structural nonlinearity and discusses in detail the problems of material micro- and macro-mechanics that are only slightly touched in existing books, e.g. stress diffusion in a unidirectional material with broken fibers, physical and statistical aspects of fiber strength, coupling effects in anisotropic and laminated materials, etc. The authors are designers of composite structures who were involved in practically all the main Soviet and then Russian projects in composite technology, and the permission of the Russian Composite Center - Central Institute of Special Machinery (CRISM) to use in this book the pictures of structures developed and fabricated in CRISM as part of the joint research and design project is much appreciated. Mechanics and Analysis of Composite Materials consists of eight chapters progressively covering all structural levels of composite materials from their components through elementary plies and layers to laminates.

Mechanics of Textile and Laminated Composites by A. Bogdanovich,Christopher M. Pastore Pdf

Mechanics of Textile and Laminated Composites is in three parts. The first part (Chapters 1 and 2) covers the fundamental issues of 3-D theory of elasticity and presents the theory of elasticity of an anisotropic body with comprehensive analysis of its specific cases. The second part (Chapters 3-5) presents the theoretical and experimental characterization of the elastic properties of unidirectional, textile and layered composite materials. The final part (Chapters 6 and 7) addresses the problems of 3-D stress analysis in laminated and textile composite structures. Major emphasis is placed on textile composites, perhaps the most complex and at the same time most promising group of composite materials. One of the most important features of this book is that it provides accurate and efficient 3-D analysis of laminated and textile reinforced structures, using novel methods. It has become more and more evident in recent years that, in many practical design situations, such full-scale 3-D analyses are required. Researchers, designers and engineers working with composite materials and structures will find this book an invaluable addition to their libraries.

Analysis of Failure in Fiber Polymer Laminates by Martin Knops Pdf

Written by Puck's pupil and appointed successor Martin Knops, this book presents Alfred Puck ́s failure model, which, among several other theories, predicts fracture limits best and describes the failure phenomena in FRP most realistically – as confirmed within the "World-wide Failure Exercise". Using Puck ́s model the composite engineer can follow the gradual failure process in a laminate and deduce from the results of the analysis how to improve the laminate design.

Stress Concentrations in Laminated Composites by Seng C. Tan Pdf

From the Author's PrefaceThe objective of this book is to provide a thorough and systematic study of the problem of laminated composites containing stress concentrations. Stress concentrations are introduced in laminated plates in the forms of circular holes, elliptical openings and straight cracks. These forms of cutouts have many practical applications, and are familiar to most engineers. Stress concentrations exist in all known structural components. Stress concentrations have great practical importance because they are normally the cause of failure. In addition to stress analyses of laminated composites, we need more fundamental understanding of the failure mode, the failure criterion, the effects on global laminate response, and the design of composites in the presence of stress concentrations. In this book, all the subjects studied are closely related to the problem of stress concentrations in laminated composites . . . . All the models are verified with many experimental results. The underlying objective of this comprehensive study is to give the readers an in-depth and thorough understanding of the problem of stress concentrations in composites. This book is the first to address the problem of laminated composites containing stress concentrations in a systematic way.
