Book excerpt: This final report documents the results of a basic research program aimed at (1) studying the high temperature failure mechanisms in ceramics, (2) establishing relationships between cavitation mechanisms and creep crack growth characteristics, and (3) developing a damage mechanism-based life prediction model. The growth rate, near-tip creep responses, and damage processes of creep cracks in a pyroceram glass-ceramic were studied under tensile loading at elevated temperatures. The results of these studies indicated that creep crack growth in the pyroceram glass-ceramic occurred both in continuous and discontinuous manners, with the damage processes manifested as the nucleation, growth, and coalescence of inhomogeneously distributed cavities and microcracks. Sintering of cavities led to the existence of a growth threshold below which the creep crack would open, blunt, but not propagate. Measurements of the total accumulated creep strain near the crack-tip revealed that creep crack extension followed a critical strain criterion. Relationships between cavitation mechanisms and creep crack growth characteristics of the glass-ceramic are discussed.

This book was released on 2012-12-06 with total page 742 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume "Deformation of Ceramic Materials II" constitutes the proceedings of an international symposium held at The Pennsyl vania State University, University Park, PA on July 20, 21, and 22, 1983. It includes studies of semiconductors and minerals which are closely related to ceramic materials. The initial conference on this topic was held in 1974 at Penn State and the proceedings were published in the volume entitled "Deformation of Ceramic Materials." This conference emphasized the deformation behavior of crystals and po1ycrysta11ine and polyphase ceramics with internationally recognized authorities as keynote lecturers on the major subtopics. Several papers dealing with cavity nucleation and creep crack growth represent a major new research thrust in ceramics since the first conference. This collection of papers represents the state-of-the art of our understanding of the plastic deformation behavior of ceramics and the crystals of which they are composed. We are grateful for the suggestions of our International Advisory Committee .in recommending experts in their respective countries to participate. We are particularly grateful that the organizers of the previous Dislocation-Point Defect Interaction Workshops agreed to participate in the Penn State Symposium as an alternative at the suggestion of Prof. A. H. Heuer. We acknowledge the financial support of the National Science Foundation for this conference.

Available in PDF, EPUB and Kindle. Book excerpt: Perspectives in Creep Fracture is a collection of studies that covers the advances in the analysis of the mechanisms involved in the process of creep fracture. The book presents nine articles that present data and discuss the theoretical advancement in the field. The text first covers the mechanisms leading to fracture in metals and ceramics, and then proceeds to tackling the problem of the nucleation of creep damage. Next, the book details the models for the growth of cracks and voids by diffusion and by plastic processes. The next two chapters deal with the creep fracture of ceramics. In the eighth chapters, the text examines the development and propagation of creep cracks. The last chapter details the theory involved in the propagation of cracks by cavitation. The book will be of great interest to researchers and practitioners of materials engineering, metallurgy, and other fields involved in fracture mechanics.

Available in PDF, EPUB and Kindle. Book excerpt: This report summarizes the results of a fundamental study involving experimental characterization and analytical modeling of grain boundary cavitation and creep crack growth in ceramics exposed to pure tensile loading. The major experimental techniques employed in the program are the use of small-angle neutron scattering to characterize cavity nucleation and growth and stereoimaging analysis to characterize the stress and strain fields associated with growing creep cracks. The major accomplishments described in the report include the design, construction, and successful testing of a creep apparatus that permits creep testing of ceramics under pure tensile loading, the determination of surface preparation conditions that are adequate for the stereoimaging analysis, and the conduct of a series of creep tests designed to characterize the kinetics of damage accumulation under pure tensile loading. Appended to the report is a manuscript that was prepared during the second year of the program titled Stochastic Aspects of Creep Cavitation in Ceramics. It is anticipated that this manuscript will provide the cornerstone for understanding creep damage and creep crack growth. Of particular interest are the development of a stochastic model of grain boundary sliding and a micromechanical model that relates the cavity nucleation rate to the statistics of grain boundary sliding events.

Download or read book Elastic Creep of Brittle Ceramics with Special Reference to Creep by Crack Growth in Aluminum Oxide written by D. P. H. Hasselman and published by . This book was released on 1981 with total page 13 pages. Available in PDF, EPUB and Kindle. Book excerpt: Elastic creep by crack growth is proposed as a mechanism of creep in polycrystalline ceramics. An analysis shows that in aluminum oxide, creep by crack growth can occur in coarse-grained microstructures and a range of temperature over which contributions of other creep mechanisms to the total creep strain are negligible. Elastic or compliance creep is the deformation which occurs as the result of a time-dependent decrease in the elastic moduli of a material under load. Originator furnished keywords include: Creep, Cracks, Elastic moduli and Aluminum oxide.

Download or read book Role of Cracks in the Creep Deformation of Polycrystalline Structural Ceramics written by and published by . This book was released on 1991 with total page 5 pages. Available in PDF, EPUB and Kindle. Book excerpt: A study was conducted concerning the role of cracks in the creep deformation and fracture behavior of polycrystalline structural ceramics. Grain boundary cavitation during creep in a course-grained alumina was found to cause a decrease in Young's modulus by as much as a factor of five, indicative of the contribution from elastic creep by crack growth and crack-enhanced creep to the total creep deformation. Multiple crack formation in a fine-grained alumina was found to increase the strain-rate sensitivity of the failure stress, as the result of strain-rate dependent decreases in Young's modulus. For alumina with glassy grain boundary phase, the one-to-one correlation between creep rate and time-to-failure presented evidence for crack enhanced creep fracture. Silicon carbides whisker-reinforcement of aluminum oxides was found to suppress cavitation, coupled with an increase in the stress exponent. A micromechanical analysis of this effect indicated that creep deformation of SiC whisker- reinforced alumina appears to be governed by stress-dependent sliding at whisker-matrix interfaces.

Available in PDF, EPUB and Kindle. Book excerpt: High Temperature Mechanical Behavior of Ceramic Composites provides an up-to-date comprehensive coverage of the mechanical behavior of ceramic matrix composites at elevated temperatures. Topics include both short-term behavior (strength, fracture toughness and R-curve behavior) and long-term behavior (creep, creep-fatigue, delayed failure and lifetime). Emphasis is on a review of fundamentals and on the mechanics and mechanisms underlying properties. This is the first time that complete information of elevated temperature behavior of ceramic composites has ever been compacted together in a single volume. Of particular importance is that each chapter, written by internationally recognized experts, includes a substantial review component enabling the new material to be put in proper perspective.
