Practical Micromechanics of Composite Materials provides an accessible treatment of micromechanical theories for the analysis and design of multi-phased composites. Written with both students and practitioners in mind and coupled with a fully functional MATLAB code to enable the solution of technologically relevant micromechanics problems, the book features an array of illustrative example problems and exercises highlighting key concepts and integrating the MATLAB code. The MATLAB scripts and functions empower readers to enhance and create new functionality tailored to their needs, and the book and code highly complement one another. The book presents classical lamination theory and then proceeds to describe how to obtain effective anisotropic properties of a unidirectional composite (ply) via micromechanics and multiscale analysis. Calculation of local fields via mechanical and thermal strain concentration tensors is presented in a unified way across several micromechanics theories. The importance of these local fields is demonstrated through the determination of consistent Margins of Safety (MoS) and failure envelopes for thermal and mechanical loading. Finally, micromechanics-based multiscale progressive damage is discussed and implemented in the accompanying MATLAB code. Emphasizes appropriate application of micromechanics theories to composite behavior Addresses multiple popular micromechanics theories, which are provided in MATLAB Discusses stresses and strains resulting from realistic thermal and mechanical loading Includes availability of solution manual for professors using the book in the classroom

Demonstrates the simplicity and effectiveness of Mathematica as the solution to practical problems in composite materials. Designed for those who need to learn how micromechanical approaches can help understand the behaviour of bodies with voids, inclusions, defects, this book is perfect for readers without a programming background. Thoroughly introducing the concept of micromechanics, it helps readers assess the deformation of solids at a localized level and analyse a body with microstructures. The author approaches this analysis using the computer algebra system Mathematica, which facilitates complex index manipulations and mathematical expressions accurately. The book begins by covering the general topics of continuum mechanics such as coordinate transformations, kinematics, stress, constitutive relationship and material symmetry. Mathematica programming is also introduced with accompanying examples. In the second half of the book, an analysis of heterogeneous materials with emphasis on composites is covered. Takes a practical approach by using Mathematica, one of the most popular programmes for symbolic computation Introduces the concept of micromechanics with worked-out examples using Mathematica code for ease of understanding Logically begins with the essentials of the topic, such as kinematics and stress, before moving to more advanced areas Applications covered include the basics of continuum mechanics, Eshelby's method, analytical and semi-analytical approaches for materials with inclusions (composites) in both infinite and finite matrix media and thermal stresses for a medium with inclusions, all with Mathematica examples Features a problem and solution section on the book’s companion website, useful for students new to the programme

The book will concentrate on the application of micromechanics to the analysis of practical engineering problems. Both classical composites represented by carbon/carbon textile laminates and applications in Civil Engineering including asphalts and masonry structures will be considered. A common denominator of these considerably distinct material systems will be randomness of their internal structure. Also, owing to their complexity, all material systems will be studied on multiple scales. Since real engineering, rather than academic, problems are of the main interest, these scales will be treated independently from each other on the grounds of fully uncoupled multi-scale analysis. Attention will be limited to elastic and viscoelastic behaviour and to the linear heat transfer analysis. To achieve this, the book will address two different approaches to the homogenization of systems with random microstructures. In particular, classical averaging schemes based on the Eshelby solution of a solitary inclusion in an infinite medium represented by the Hashin-Shtrikman variational principles or by considerably simpler and more popular Mori-Tanaka method will be compared to detailed finite element simulations of a certain representative volume element (RVE) representing accommodated geometrical details of respective microstructures. These are derived by matching material statistics such as the one- and two-point probability functions of real and artificial microstructures. The latter one is termed the statistically equivalent periodic unit cell owing to the assumed periodic arrangement of reinforcements (carbon fibres, carbon fibre tows, stones or masonry bricks) in a certain matrix (carbon matrix, asphalt mastic, mortar). Other types of materials will be introduced in the form of exercises with emphases to the application of the Mori-Tanaka method in the framework of the previously mentioned uncoupled multi-scale analysis

Smart Composites: Mechanics and Design addresses the current progress in the mechanics and design of smart composites and multifunctional structures. Divided into three parts, it covers characterization of properties, analyses, and design of various advanced composite material systems with an emphasis on the coupled mechanical and non-mechanical behaviors. Part one includes analyses of smart materials related to electrically conductive, magnetostrictive nanocomposites and design of active fiber composites. These discussions include several techniques and challenges in manufacturing smart composites and characterizing coupled properties, as well as the analyses of composite structures at various length and time scales undergoing coupled mechanical and non-mechanical stimuli considering elastic, viscoelastic (and/or viscoplastic), fatigue, and damage behaviors. Part two is dedicated to a higher-scale analysis of smart structures with topics such as piezoelectrically actuated bistable composites, wing morphing design using macrofiber composites, and multifunctional layered composite beams. The analytical expressions for characterization of the smart structures are presented with an attention to practical application. Finally, part three presents recent advances regarding sensing and structural health monitoring with a focus on how the sensing abilities can be integrated within the material and provide continuous sensing, recognizing that multifunctional materials can be designed to both improve and enhance the health-monitoring capabilities and also enable effective nondestructive evaluation. Smart Composites: Mechanics and Design is an essential text for those interested in materials that not only possess the classical properties of stiffness and strength, but also act as actuators under a variety of external stimuli, provide passive and active response to enable structural health monitoring, facilitate advanced nondestructive testing strategies, and enable shape-changing and morphing structures.

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· What is Dimensional Stability? · Historical Notes· Magnitude: Units, Range, Engineering vs. True Strain, Dependence on Measurement Chapter II: DIMENSIONALLY STABLE MATERIALS· Introduction · Metals and Alloys · Glasses and Ceramics· Polymers· General Composites · Composite Constituents· Metal Matrix Composites· Ceramic Matrix Composites· Polymer Matrix Composites· Carbon Matrix Composites· Natural Composites· Hybrid Composites· Shape Memory Materials · Functionally Graded Materials· Nanomaterials· "In situ" Composites Chapter III: MECHANICAL EFFECTS· Introduction · Composite Notation· Micromechanics· Macromechanics of Laminates· Orthotropic Materials· Curvature · Thickness Effects· Poisson''s Ratio· Edge/End Effects· Residual Stresses· Plastic Deformation · Microyield Stress· References Chapter IV: ENVIRONMENTAL EFFECTS-TEMPERATURE· Introduction · CTE of Constituents · Micromechanics· Macromechanics· Volumetric Expansion· Resin Matrix Composites · Metal Matrix Composites· Ceramic Matrix Composites· Uniformity of CTE· Structural Forms· References Chapter V: ENVIRONMENTAL EFFECTS-MASS ABSORPTION· Introduction· Moisture Content· Moisture Distribution· Moisture Induced Strain · Coatings · CME Data Chapter VI: ENVIRONMENTAL EFFECTS-RADIATION · Introduction· Space Radiation· Radiation Effects on Micromechanical Properties· Radiation Effects on Thermophysical Properties· Nuclear Radiation · UV and Miscellaneous Radiation Chapter VII: ENVIRONMENTAL EFFECTS-TIME · Introduction · Temporal Stability · Relaxation of Residual Stresses· Physical Aging· Chemical Aging · Thermal Aging· Post Curing Chapter VIII: CREEP· Introduction· General Creep Behavior· Creep of Composite Constituents· Microstructure· Loading Conditions· Creep Mechanisms· Recovery and Relaxation· Damage Development· Prediction of Creep Strains Chapter IX: INTERNAL DAMAGE· Introduction· Thermally Induced Microcracking in FRPL· Mechanical (Stress) Cycling in PMC· Dimensional Changes due to Microcracking· Effects of Microcracking on Dimensional Stability, Effect on CTE, Thermal Cycling of PMC, Effects on Micromechanical Properties · Methods to Minimize Microcracking· Thermal Spikes· Reverse Thermal Effect· Thermal Cycling of MMC· Thermal Cycling of CMC· Microcracking and Moisture· Role of Fiber/Matrix Interface· Surface Damage Chapter X: COMBINED EFFECTS· Introduction · Thermoelasticity· Effect of Stress on Thermal Expansion· Hygrothermoelasticity · Effects of Stress on Mass Diffusivity· Stress and Moisture Effects· The Mechanosorptive Effect· Moisture Cycling· Combined Stress-Moisture-Damage Chapter XI: MEASUREMENT TECHNIQUES · Introduction· General Metrology· Microyield Strength (MYS)· Thermal Expansion (CTE)· Moisture Expansion (CME)· Temporal Stability· Creep· Damage Induced Dimensional Changes· Techniques for Combined Effects· Related Techniques Chapter XII: APPLICATIONS· Introduction · Dimensionally Stable Requirements· Selected Applications: Aircraft, Antenna Structures, Automotive, Biomedical, Cryogenics, Electronics, Fabrication, Flywheels, High Temperature, Instrument Components, Large Space Structures, Metering Functions, Microwave Components, Mirrors, Optical Support Structures, Radiation Environments, Radomes, Smart Materials Technology, Spacecraft Components, Structural/Infrastructure, Wind Turbines, General Design Methodology Index

The major goal of this book is to present the implementation of some damage models with finite elements. The damage models are based on the principles of continuum damage mechanics and the effective stress concept. Several books have appeared recently on damage mechanics but are mostly theoretical in nature. Alternatively, this book provides a complete finite element program that includes the effects of damage. The book consists of two parts. Part I includes two chapters mainly review ing topics from finite element analysis and continuum damage mechanics. The reader is cautioned that the material contained in this part is introductor- other references must be consulted for the theoretical aspects of these topics. For a complete theoretical treatment of the subject, the reader is referred to the book Advances in Damage Mechanics: Metals and Metal Matrix Composites by Voyiadjis and Kattan, published in 1999. In Part II the finite element program DNA is introduced in three chapters. DNA stands for "Da mage Nonlinear Analysis". The program can be used for the analysis of elasto plastic material behavior including the effects of damage within the frame work of damage mechanics. Two versions of DNA are presented - one for small strain analysis and one for finite strain analysis. The program makes extensive calls to a library of tensor operations developed by the authors. The tensor library is extensively outlined in the last chapter of the book.

Designing structures using composite materials poses unique challenges due especially to the need for concurrent design of both material and structure. Students are faced with two options: textbooks that teach the theory of advanced mechanics of composites, but lack computational examples of advanced analysis; and books on finite element analysis that may or may not demonstrate very limited applications to composites. But now there is third option that makes the other two obsolete: Ever J. Barbero's Finite Element Analysis of Composite Materials. By layering detailed theoretical and conceptual discussions with fully developed examples, this text supplies the missing link between theory and implementation. In-depth discussions cover all of the major aspects of advanced analysis, including three-dimensional effects, viscoelasticity, edge effects, elastic instability, damage, and delamination. More than 50 complete examples using mainly ANSYSTM, but also including some use of MATLAB®, demonstrate how to use the concepts to formulate and execute finite element analyses and how to interpret the results in engineering terms. Additionally, the source code for each example is available for download online. Cementing applied computational and analytical experience to a firm foundation of basic concepts and theory, Finite Element Analysis of Composite Materials offers a modern, practical, and versatile classroom tool for today's engineering classroom.

This textbook demonstrates the application of the finite element philosophy to the solution of real-world problems and is aimed at graduate level students, but is also suitable for advanced undergraduate students. An essential part of an engineer’s training is the development of the skills necessary to analyse and predict the behaviour of engineering systems under a wide range of potentially complex loading conditions. Only a small proportion of real-life problems can be solved analytically, and consequently, there arises the need to be able to use numerical methods capable of simulating real phenomena accurately. The finite element (FE) method is one such widely used numerical method. Finite Element Applications begins with demystifying the ‘black box’ of finite element solvers and progresses to addressing the different pillars that make up a robust finite element solution framework. These pillars include: domain creation, mesh generation and element formulations, boundary conditions, and material response considerations. Readers of this book will be equipped with the ability to develop models of real-world problems using industry-standard finite element packages.
