The fracture mirror and crack branching constants were determined from three glasses and nine advanced ceramics tested under various loading and specimen configurations in an attempt to use the constants as a data base for fractography. The ratios of fracture mirror or crack branching constant to fracture toughness were found to be approximately two for most ceramic materials tested. A demonstration of how to use the two constants as a tool for verifying stress measurements was presented for silicon nitride disk specimens subjected to high-temperature, constant stress-rate biaxial flexure testing.

Supports the use and development of strong, fracture-resistant, and mechanically reliable ceramic materials The Fracture of Brittle Materials thoroughly sets forth the key scientific and engineering concepts underlying the selection of test procedures for fracture toughness, strength determination, and reliability predictions. With this book as their guide, readers can confidently test and analyze a broad range of brittle materials in order to make the best use of existing materials as well as to support the development of new materials. The authors explain the importance of microstructure in these determinations and describe the use of quantitative fractography in failure analysis. The Fracture of Brittle Materials is relevant to a broad range of ceramic materials (i.e., any inorganic non-metal), including semiconductors, cements and concrete, oxides, carbides, and nitrides. The book covers such topics as: Basic principles of fracture mechanics underlying brittle material tests and analysis procedures Theory and mechanisms of environmentally enhanced crack growth Fracture mechanics tests to determine a material's resistance to fast fracture Test and analysis methods to assess the strength of ceramics Methods to analyze the fracture process based on quantitative measurements of the fracture surface Effect of a material's microstructure Methods for predicting the lifetime of brittle components under stress Throughout the book, figures and illustrations help readers understand key concepts and methods. Replete with real-world examples, this text enables engineers and materials and ceramics scientists to select and implement the optimal testing methods for their particular research needs and then accurately analyze the results.

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

The widespread dissemination of fractographic literature on metals and polymers has been notably useful to those concerned with the development and application of those materials. Glasses and ceramics have also seen application of fractographic principles to a point where it was felt to be valuable to convene a conference where exchange of relevant information could take place. Contents of this report includes: High-Temperature Fracture; Role of Strain-Softening by Crack Formation in the Non-Linear Stress-Strain Behavior of a Polycrystalline Alumina at High Temperature; Fractography and Fracture Mechanics; Fracture Mechanics of Crack Branching in Ceramics; A Dynamic Fracture Mechanics Interpretation of Multiple Mist Regions on Soda-Lime-Silicate Glass Fracture Surfaces.
