This monograph consists of two volumes and provides a unified, comprehensive presentation of the important topics pertaining to the understanding and determination of the mechanical behaviour of engineering materials under different regimes of loading. The large subject area is separated into eighteen chapters and four appendices, all self-contained, which give a complete picture and allow a thorough understanding of the current status and future direction of individual topics. Volume I contains eight chapters and three appendices, and concerns itself with the basic concepts pertaining to the entire monograph, together with the response behaviour of engineering materials under static and quasi-static loading. Thus, Volume I is dedicated to the introduction, the basic concepts and principles of the mechanical response of engineering materials, together with the relevant analysis of elastic, elastic-plastic, and viscoelastic behaviour. Volume II consists of ten chapters and one appendix, and concerns itself with the mechanical behaviour of various classes of materials under dynamic loading, together with the effects of local and microstructural phenomena on the response behaviour of the material. Volume II also contains selected topics concerning intelligent material systems, and pattern recognition and classification methodology for the characterization of material response states. The monograph contains a large number of illustrations, numerical examples and solved problems. The majority of chapters also contain a large number of review problems to challenge the reader. The monograph can be used as a textbook in science and engineering, for third and fourth undergraduate levels, as wellas for the graduate levels. It is also a definitive reference work for scientists and engineers involved in the production, processing and applications of engineering materials, as well as for other professionals who are involved in the engineering design process.

Provided by this book is a unified, comprehensive presentation of the foundations of the theory of viscoelastic solids. The large subject area is separated into self-contained chapters that give a full complete picture and allow a thorough understanding of the current status and future direction of individual topics. The author emphasizes the basic principles along with topics of fundamental importance to the understanding of viscoelasticity in its different regimes. Particular attention is paid to experimental activity, numerical characterization of the response of advanced industrial materials and the solution of the different categories of the associated boundary value problem. This book should be of interest to engineers and scientists working in all fields of materials, but especially the following: polymers; rubbers; plastics; fibres; pulp and paper; biomaterials; medical engineering; materials R mechanics of materials; evaluation and testing; engineering and medical applications. It should also be of interest to final year and postgraduate students and researchers in materials science at university level.

There are new and emergent technologies - in the aerospace industry, advanced civil and mechanical structures, smart' materials, biomaterials, microelectronics, etc. - which demand materials with particular response characteristics that cannot be met by conventional, monolithic systems. Composite materials, including laminated and fibre-reinforced systems, play significant roles in many scientific and engineering realms, primarily due to their unique physical and mechanical response characteristics, such as specific strength, fracture toughness, corrosion and wear resistance. These characteristics can be enhanced by the ability of the materials scientist and engineer to tailor the microstructure to suit the imposed working conditions. In Advanced Multilayered and Fibre-Reinforced Composites, leading researchers present the latest advances in the areas of ceramic, metallic and polymeric composite systems, including new classes of ceramic composites. The book emphasises the significance of local deformation effects and the principles and approaches of advanced experimental mechanics in the service of modern technology. There is a comprehensive treatment of functionally graded materials and the various approaches to modelling the mechanical behaviour of multi-phase solids. The unified and comprehensive treatment means that the book can be used as a text for science and engineering students from senior undergraduate level upwards. It also forms a comprehensive reference for scientists and engineers involved in the design, processing and application of composite materials.
