Aerospace structural design, especially for large aircraft, is an empirical pursuit dominated by rules of thumb and often-painful service experiences. Expertise on traditional materials is not transferable to "new? materials, processes and structural concepts. This is because it is not based on or derived from well-defined measures of safety. This book addresses the need for safe innovation based on practical, explicit structural safety constraints for use in innovative structures of the future where guiding service experience is non-existent. The book covers new ground by the demonst

In recent years, Low Temperature Cofired Ceramics (LTCC) have become an attractive technology for electronic components and substrates that are compact, light, and offer high-speed and functionality for portable electronic devices such as the cellular phones, personal digital assistants (PDA) and personal computers used for wireless voice and data communication in rapidly expanding mobile network systems. LTCC are especially suitable for the high frequency circuits required for high-speed data communications. LTCCs are made by combining ceramic insulating materials, conductor materials, and other materials through numerous processes culminating in co-firing. The materials and the processes used are therefore interdependent. By ensuring the consistency between materials and processes, it is possible to achieve circuit boards and various types of high frequency passive components and so on with the desired characteristics. This book describes the general technical information of each material (ceramic, conductor, and resistor materials) and each process, and it offers commentaries on unique examples resulting from these interrelations.

Plates and panels are primary components in many structures including space vehicles, aircraft, automobiles, buildings, bridge decks, ships and submarines. The ability to design, analyse, optimise and select the proper materials for these structures is a necessity for structural designers, analysts and researchers. This text consists of four parts. The first deals with plates of isotropic (metallic and polymeric) materials. The second involves composite material plates, including anisotropy and laminate considerations. The third section treats sandwich constructions of various types, and the final section gives an introduction to plates involving piezoelectric materials, in which the "smart" or "intelligent" materials are used as actuators or sensors. In each section, the formulations encompass plate structures subjected to static loads, dynamic loads, buckling, thermal/moisture environments, and minimum weight structural optimisation. This is a textbook for a graduate course, an undergraduate senior course and a reference. Many homework problems are given in various chapters.

Ceramic matrix composites (CMCs) are at the forefront of advanced materials technology because of their light weight, high strength and toughness, high temperature capabilities, and graceful failure under loading. During the last 25 years, tremendous progress has been made in the development and advancement of CMCs under various research programs funded by the U.S. Government agencies: National Aeronautics and Space Administration (NASA), Department of Defense (DoD), and Department of Energy (DOE). Ceramic composites are considered as enabling technology for advanced aeropropulsion, space propulsion, space power, aerospace vehicles, and space structures. CMCs would also find applications in advanced aerojet engines, stationary gas turbines for electrical power generation, heat exchangers, hot gas filters, radiant burners, heat treatment and materials growth furnaces, nuclear fusion reactors, automobiles, biological implants, etc. Other applications of CMCs are as machinery wear parts, cutting and forming tools, valve seals, high precision ball bearings for corrosive environments, and plungers for chemical pumps. Potential applications of various ceramic composites are described in individual chapters of the present handbook. HANDBOOK OF CERAMIC COMPOSITES is different from the other books available on this topic. Here, a ceramic composite system or a class of composites has been covered in a separate chapter, presenting a detailed description of processing, properties, and applications. Each chapter is written by internationally renowned researchers in the field. The handbook is organized into five sections: Ceramic Fibers, Non-oxide/Non-oxide Composites, Non-oxide/Oxide Composites, Oxide/Oxide Composites, and Glass and Glass-Ceramic Composites. This Handbook should be a valuable source of information for scientists, engineers, and technicians working in the field of CMCs and also for designers to design parts and components for advanced engines and various other industrial applications.

Graded Ferroelectrics, Transpacitors and Transponents details the experimental and theoretical aspects of newly emerging ferroelectric devices, and their extensions to other ferroic systems such as: ferromagnetics, ferroelastics, piezoelectrics, etc. The theory and experimental results pertaining to non-homogeneous active ferroic devices and structures are presented The primary focus of the book is directed toward polarization-graded ferroelectrics and their active components - transpacitors; however, the findings here are quite general. The theory of graded ferroics is put on a solid foundation in Chapters 2 and 5, whereas much of the introductory material relies more heavily upon analogy. This was done so as to provide the reader with an intuitive approach to graded ferroics. Heterogeneous ferroics are shown as logical extensions of passive semiconductor junction devices such as p-n and n-p diodes and their active manifestations: transistors, to transpacitors, transductors, translastics and ultimately to the general active ferroic elements, transponents.
