Book Description
A Comprehensive and Self-Contained Treatment of the Theory and Practical Applications of Ceramic Materials When failure occurs in ceramic materials, it is often catastrophic, instantaneous, and total. Now in its Second Edition, this important book arms readers with a thorough and accurate understanding of the causes of these failures and how to design ceramics for failure avoidance. It systematically covers: Stress and strain Types of mechanical behavior Strength of defect-free solids Linear elastic fracture mechanics Measurements of elasticity, strength, and fracture toughness Subcritical crack propagation Toughening mechanisms in ceramics Effects of microstructure on toughness and strength Cyclic fatigue of ceramics Thermal stress and thermal shock in ceramics Fractography Dislocation and plastic deformation in ceramics Creep and superplasticity of ceramics Creep rupture at high temperatures and safe life design Hardness and wear And more While maintaining the first edition's reputation for being an indispensable professional resource, this new edition has been updated with sketches, explanations, figures, tables, summaries, and problem sets to make it more student-friendly as a textbook in undergraduate and graduate courses on the mechanical properties of ceramics.

Book Description
This report describes a study of the strength impact and fracture behaviour of a range of ceramic materials. One part of the research is concerned with ceramics which have applications as radomes or infra-red transmitting window materials, the other with ceramics with potential application in body armour. Ceramics included in the study include zinc sulphide, various glass ceramics and aluminas, silicon carbide, silicon nitride, titanium diboride and boron carbide. in one series of experiments we have measured post-impact (i.e. residual) strength curves. These experiments involve impacting specimens at chosen velocities and then measuring the residual strengths after impact. Strength is plotted as a function of velocity. Such curves give: (i) the threshold velocity above which strength degradation following impact occurs; (ii) the fall in strength above the threshold; (iii) a ready comparison with other materials or between different batches of the same material which have had, for example, different surface preparations. From these strength curves, it is ... possible to estimate the size of the flaws which control the damage. Microscopy studies of the fracture faces have been made to locate the nucleating flaws so that there is a crosscheck with the flaw sizes calculated. In cases where physical property data were not available, they were measured. Tables give data on hardness, fracture toughness, elastic moduli, stress wave and fracture velocities.

Book Description
These volumes, 7 and 8, of Fracture Mechanics of Ceramics constitute the proceedings of an international symposium on the fracture mechanics of ceramic materials held at Virginia Polytechnic Institute and State University, Blacksburg, Virginia on June 19, 20 and 21, 1985. These proceedings constitute the fourth pair of volumes of a continuing series of conferences. The theme of this conference, as the previous three, focused on the mechanical behavior of ceramic materials in terms of the characteristics of cracks, particularly the roles which they assume in the fracture process. The 78 contributed papers by over 100 authors and co-authors represent the current state of the field. They address many of the theoretical and practical problems of interest to those concerned with brittle fracture. The program chairmen gratefully acknowledge the financial assistance for the Symposium provided by the EXXON Foundation, the Army Research Office, the Natio~al Science Foundation, and the Office of Naval Research. Without their support, this conference simply would not have been possible. The suggestions of Drs. J. C. Hurt, R. C. Pohanka, and L. Toth were particularly helpful in assuring the success of this symposium. Special appreciation is extended to Professor J. I. Robertson, C. P. Miles Professor of History. whose presentation following the banquet on the American Civil War was very well received by the audience. Finally, we wish to also thank our joint secretaries, especially Karen Snider, for their patience and help in finally bringing these proceedings to press.

Book Description
Hardbound. This book provides a thorough review on the actual trends in basic and applied research on the strength and fracture of glass and ceramics. The book will prove a useful and dynamic tool for research workers, designers and technologists engaged in the development and manufacture of ceramics or glass. It will also be of use to anybody interested in the strength and fracture of brittle materials.There is a growing demand for a much wider application of ceramics and glass, even in the cases where mechanical load cannot be neglected. This trend is being met with the development of new advanced ceramic and glass materials with markedly better mechanical properties. In the future ceramics will be used increasingly for highly stressed parts of high-temperature heat exchangers, gas turbines, rocket engines and other equipment. A new branch of science called fracture mechanics has been developed, which allows the characterization and description of fai
