Annotation ? Comprehensive numerical presentation of dimensional instability in composites? Quantitative analyses for predicting deformations in all types of composite materials? Evaluation of mechanical, thermophysical, environmental stresses over time? Unique aid in design of composites for specific application conditions--This book is a comprehensive introduction to the quantitative analysis of dimensional instability in composite materials. It will aid in predicting deformations in a wide range of composite materials products and parts, under mechanical, thermophysical, and environmental stresses over time. Written by an internationally known expert on the analysis of composites, this new work brings together the best quantitative methods and currently known data for understanding how composites become unstable over time. The technical insights and information in this book offer a practical foundation for engineering composite materials with better stability and increased performance. From The Author''s Preface "Dimensional stability predictions [in composites] require knowledge of not only mechanical behavior but also thermophysical properties and the response to environmental conditions and time. This book attempts to aid in the numerical prediction of dimensional stability properties. It is necessary to quantify the behavior of composites for many reasons. Composites compete with plastics, metals, and ceramics in numerous applications, and designers must be able to justify increase in cost or complexity in terms of precisely defined performance benefits ... Only a quantitative understanding of potential deformations [in composites] will lead to confidence in their use ... This book combines a judicious use of experimental data, together with current theoretical models. It summarizes the scope of potential sources of instability in composites to help the engineer estimate the magnitude of possible deformations. The book also contributes to outlining methods for dealing with deformations. Experimental methods are offered and reviewed for those who (wisely) do not rely solely on existing data and theory."--TABLE OF CONTENTS PrefaceAcknowledgments Chapter I: INTRODUCTION?

This book balances introduction to the basic concepts of the mechanical behavior of composite materials and laminated composite structures. It covers topics from micromechanics and macromechanics to lamination theory and plate bending, buckling, and vibration, clarifying the physical significance of composite materials. In addition to the materials covered in the first edition, this book includes more theory-experiment comparisons and updated information on the design of composite materials.
Many years of cumulative research has been conducted on the usage of fiber-reinforced composites for biomedical application, but no one source exists where this topic is dealt with systematically. This book addresses polymer composites applied to bioengineering in a comprehensive manner.For potential applications to be successful, full advantage must be taken of the materials properties and the manufacturing techniques to meet the needs of biomedical application. This book focuses on fiber-based composites applied to bioengineering. It addresses three main areas. First, it presents a comprehensive survey of biocomposites from the existing literature in various medical applications, paying particular attention to hard-tissue-related implants. Second, mechanical designs and manufacturing aspects of various fibrous polymer matrix composites are described. The third area concerns examples of the design and development of several medical devices and implants using polymer composites.Chapter 1: Introduction (288 KB)
Presenting a new set of 158 solved problems and projects to supplement the Examples and Exercises available in the textbook Introduction to Composite Materials Design-THIRD edition from CRC Press (2018). This is a companion to that textbook, with frequent cross-referencing guiding the reader to the equations, figures, tables, and specific sections of the textbook relevant for understanding every part of the solution to each of the problems. This workbook does not contain solutions for the Exercises at the end of the chapters in the textbook. Instead, this workbook offers a completely new set of problems, accompanied by detailed step-by-step solutions. These include additional explanations, new figures, and new references to popular design handbooks, material property data, and other sources from the literature. As well as solved problems, this workbook features several complete term-paper ideas in Chapters 2 (Materials) and 3 (Processing). Each idea provides a brief introduction to the solution of each term-paper, and a few citations as a starting point for further study. The Appendix contains a number of project ideas challenging enough to be assigned as semester-long team projects.At the end of each chapter, additional challenge exercises provide an additional opportunity for the reader to master the subject. Most problems are solved by hand, showing every step, with all numerical values substituted into equations from the textbook, ending with the numerical answer to the problem. Wherever computer code is helpful for completing the calculations, the code has been written and displayed using the free, open source language Scilab(TM), similar to MATLAB(R). A few problems are also solved using the free on-line application CADEC (http://cadec-online.com).The THIRD edition of the textbook "Introduction to Composite Materials Design (2018)" implements a number of additions and changes with respect to the second edition. The sign of bending moment is reversed to agree with the standard Mechanics of Materials convention, so all problems involving moment and curvature have been updated. The numbering of Equations, Sections, and Tables are updated. Each table that was landscape in the second edition is now split into two tables to make it easier to read the eBook version of the textbook in portrait mode, so tables numbering has changed significantly. New topics have been added such as Basis Values, Temperature-Dependent Properties, Universal Carpet Plots (in three chapters), and many more, requiring new Problems in this WorkBook. Some equations are rewritten to simplify numerical computations, and those changes are reflected in this WorkBook. In summary, one cannot use the old WorkBook with the third edition of the textbook. Furthermore, this edition has more problems, more Scilab code, and more thorough explanations of the solutions.
La 4ème de couverture indique : "This book weaves together the basic concepts, mathematical fundamentals, and formulations of micromechanics into a systemic approach for understanding and modeling the effective material behavior of composite materials. As various emerging composite materials have been increasingly used in civil, mechanical, biomedical, and materials engineering, this textbook provides students with a fundamental understanding of the mechanical behavior of composite materials and prepares them for further research and development work with new composite materials. The content is organized in accordance with a rigorous course. It covers micromechanics theory, the microstructure of materials, homogenization, and constitutive models of different types of composite materials, and it enables students to interpret and predict the effective mechanical properties of existing and emerging composites through microstructure-based modeling and design. As a prerequisite, students should already understand the concepts of boundary value problems in solid mechanics. Introduction to the Micromechanics of Composite Materials is suitable for senior undergraduate and graduate students".
In 1997, Dr. Kaw introduced the first edition of Mechanics of Composite Materials, receiving high praise for its comprehensive scope and detailed examples. He also introduced the groundbreaking PROMAL software, a valuable tool for designing and analyzing structures made of composite materials. Updated and expanded to reflect recent advances in the field, this Second Edition retains all of the features -- logical, streamlined organization; thorough coverage; and self-contained treatment -- that made the first edition a bestseller. The book begins with a question-and-answer style introduction to composite materials, including fresh material on new applications. The remainder of the book discusses macromechanical analysis of both individual lamina and laminate materials; micromechanical analysis of lamina including elasticity based models; failure, analysis, and design of laminates; and symmetrical and nonsymmetrical beams (new chapter). New examples and derivations are included in the chapters on micromechanical and macromechanical analysis of lamina, and the design chapter contains two new examples: design of a pressure vessel and design of a drive shaft. The author also adds key terms and a summary to each chapter. The most current PROMAL software is available via the author's often-updated Web site, along with new multiple-choice questions. With superior tools and complete coverage, Mechanics of Composite Materials, Second Edition makes it easier than ever to integrate composite materials into your designs with confidence.
