The book presents interesting examples of recent developments in this area. Among the studied materials are bulk metallic glasses, metamaterials, special composites, piezoelectric smart structures, nonwovens, etc. The last decades have seen a large extension of types of materials employed in various applications. In many cases these materials demonstrate mechanical properties and performance that vary significantly from those of their traditional counterparts. Such uniqueness is sought – or even specially manufactured – to meet increased requirements on modern components and structures related to their specific use. As a result, mechanical behaviors of these materials under different loading and environmental conditions are outside the boundaries of traditional mechanics of materials, presupposing development of new characterization techniques, theoretical descriptions and numerical tools. The book presents interesting examples of recent developments in this area.

This book focuses on the mathematical potential and computational efficiency of the Boundary Element Method (BEM) for modeling seismic wave propagation in either continuous or discrete inhomogeneous elastic/viscoelastic, isotropic/anisotropic media containing multiple cavities, cracks, inclusions and surface topography. BEM models may take into account the entire seismic wave path from the seismic source through the geological deposits all the way up to the local site under consideration. The general presentation of the theoretical basis of elastodynamics for inhomogeneous and heterogeneous continua in the first part is followed by the analytical derivation of fundamental solutions and Green's functions for the governing field equations by the usage of Fourier and Radon transforms. The numerical implementation of the BEM is for antiplane in the second part as well as for plane strain boundary value problems in the third part. Verification studies and parametric analysis appear throughout the book, as do both recent references and seminal ones from the past. Since the background of the authors is in solid mechanics and mathematical physics, the presented BEM formulations are valid for many areas such as civil engineering, geophysics, material science and all others concerning elastic wave propagation through inhomogeneous and heterogeneous media. The material presented in this book is suitable for self-study. The book is written at a level suitable for advanced undergraduates or beginning graduate students in solid mechanics, computational mechanics and fracture mechanics.
In this textbook for students of laminated composite materials, composite structures, and anisotropic elasticity, Chyanbin Hwu draws on more than three decades of research and applications experience to provide a leading resource on many unique topics related to laminated composite structures. This book introduces the mechanical behavior of laminated composite materials and provides related theories and solutions. All basic structural elements such as beams, plates, and shells are described in detail. Further contents include composite sandwich construction and composite wing structures. To connect with practical engineering applications and analyze more complicated real structures, numerical methods and their theoretical basis in anisotropic elasticity are also included. Advanced topics addressed include solutions for magneto-electro-elastic laminated plates; Green’s functions for thick laminated plates and beams; typical thick laminated beams; theory for general laminated composite shells; sandwich beams, plates, and cylindrical shells as well as delaminated composite sandwich beams; modeling and analysis of composite wing structures; complex variable theories of anisotropic elasticity and the related Green’s functions; and numerical methods such as finite element method, boundary element method and meshless method. Through this book, readers will learn not only the mechanics of laminated composite structures but also anisotropic elasticity and some popular numerical methods. This textbook is vital for advanced undergraduate and graduate students interested in the mechanics of composite materials, composite structures, and anisotropic elasticity, such as aerospace, mechanical, civil, and naval engineering; applied mechanics; and engineering science. It is also useful for engineers working in these fields and applied mathematicians and material scientists.
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
