Despite the significant progress, which has been made in developing of ceramic materials desired for engineering applications, their mass production is still not on expected level. Among the key factors hindering higher exploitation of these materials the problems in processing were identified. The processing comprises powder production, mixing techniques, forming, and sintering. All of them are equally important and all of them can introduce defects into the material. Besides improvement in processing, the properties of ceramic materials can be considerably improved by the creation of composites. Composites formed at micro or macro level are able to form more flaw-tolerant material. Considerable research activities, working on above mentioned phenomena are in progress at industrial laboratories as well as other research centres. This volume presents the contributions to the Advanced Research Workshop "Engineering Ceramics '96" with 65 participants from 21 countries held on 12th - 15th May 1996 at Smolenice Castle, Slovakia, the conference site of Slovak Academy of Sciences. The book covers research activities on engineering ceramic materials and gives an overview with respect to recent developments.

Application of heat to clay transforms it into a ceramic, and thus the history and technical features of structures supplying that heat - kilns - are of considerable importance. The 14 chapters in this volume discuss ancient and historic kilns from the viewpoint of their excavation, their operational principles, and their contributions to an understanding of ceramic production within ancient economies.

This thesis deals with the processes that create ordered assemblies from disordered nanoparticles. Ordered packings of nanoscale particles can exhibit unusual properties. This work investigates the self-assembly of such particles, a process widely employed for the generation of ordered structures, but not yet well understood. In situ methods are used to observe the assembly of sub-micron polymer lattices and sub-10 nm gold particles into crystalline monolayers and aggregates. On the basis of these results, the book develops new models that describe the competition between different influences, such as thermal agitation and directional forces. It suggests necessary criteria that lead to the emergence of order.

Fiberglass and Glass Technology: Energy-Friendly Compositions and Applications provides a detailed overview of fiber, float and container glass technology with special emphasis on energy- and environmentally-friendly compositions, applications and manufacturing practices which have recently become available and continue to emerge. Energy-friendly compositions are variants of incumbent fiberglass and glass compositions that are obtained by the reformulation of incumbent compositions to reduce the viscosity and thereby the energy demand. Environmentally-friendly compositions are variants of incumbent fiber, float and container glass compositions that are obtained by the reformulation of incumbent compositions to reduce environmentally harmful emissions from their melts. Energy- and environmentally-friendly compositions are expected to become a key factor in the future for the fiberglass and glass industries. This book consists of two complementary sections: continuous glass fiber technology and soda-lime-silica glass technology. Important topics covered include: o Commercial and experimental compositions and products o Design of energy- and environmentally-friendly compositions o Emerging glass melting technologies including plasma melting o Fiberglass composite design and engineering o Emerging fiberglass applications and markets Fiberglass and Glass Technology: Energy-Friendly Compositions and Applications is written for researchers and engineers seeking a modern understanding of glass technology and the development of future products that are more energy- and environmentally-friendly than current products.

This book presents a broad view of the current state of the art regarding the dynamic response of composite and sandwich structures subjected to impacts and explosions. Each chapter combines a thorough assessment of the literature with original contributions made by the authors. The first section deals with fluid-structure interactions in marine structures. The first chapter focuses on hull slamming and particularly cases in which the deformation of the structure affects the motion of the fluid during the water entry of flexible hulls. Chapter 2 presents an extensive series of tests underwater and in the air to determine the effects of explosions on composite and sandwich structures. Full-scale structures were subjected to significant explosive charges, and such results are extremely rare in the open literature. Chapter 3 describes a simple geometrical theory of diffraction for describing the interaction of an underwater blast wave with submerged structures. The second section addresses the problem of impact on laminated composite structures with chapters devoted to ballistic impacts on pre-stressed composite structures, tests developed to simulate dynamic failure in marine structures, damage mechanisms and energy absorption in low velocity impacts, perforation, the numerical simulation of intra and inter-ply damage during impact, and hail impact on laminated composites. Sandwich structures with laminated facings are considered in Section 3 with chapters dealing with the discrete modeling of honeycomb core during the indentation of sandwich structures, the behavior of fold core sandwich structures during impact, and impact on helicopter blades. The fourth section consists of two chapters presenting experimental results and numerical simulation of composite structures subjected to crash. This volume is intended for advanced undergraduate and graduate students, researchers, and engineers interested and involved in analysis and design of composite structures.

Adaptive structural systems in conjunction with multifunctional materials facilitate technical solutions with a wide spectrum of applications and a high degree of integration. By virtue of combining the actuation and sensing capabilities of piezoelectric materials with the advantages of fiber composites, the anisotropic constitutive properties may be tailored according to requirements and the failure behavior can be improved. Such adaptive fiber composites are very well-suited for the task of noise and vibration reduction. In this respect the helicopter rotor system represents a very interesting and widely perceptible field of application. The occurring oscillations can be reduced with aid of aerodynamic couplings via fast manipulation of the angle of attack, being induced by twist actuation of the rotor blade. On the one hand the sensing properties may be used to determine the current state of deformation, while on the other hand the actuation properties may be used to attain the required state of deformation. The implementation of such concepts requires comprehensive knowledge of the theoretical context, which shall be illuminated in the work at hand from the examination of the material behavior to the simulation of the rotating structure.
