This book was released on 1993 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper summarizes recent experimental results on creep and creep rupture behavior of a commercial grade of Si3N4 ceramic in the temperature range of 1150 to 1300C obtained at ORNL; and introduces a tentative multiaxial deformation and life prediction model for ceramic materials under general thermomechanical loadings. Issues related to the possible standardization of the data analysis methodology and possible future research needs for high temperature structural ceramics in the area of development of data base and life prediction methodology are also discussed.

This book was released on 1992 with total page 11 pages. Available in PDF, EPUB and Kindle. Book excerpt: A constitutive model capable of describing deformation and predicting rupture life was developed for high temperature ceramic materials under general thermal-mechanical loading conditions. The model was developed based on the deformation and fracture behavior observed from a systematic experimental study on an advanced silicon nitride (Si3N4) ceramic material. Validity of the model was evaluated with reference to creep and creep rupture data obtained under constant and stepwise-varied loading conditions, including the effects of annealing on creep and creep rupture behavior.

Download or read book A Comparative Study of Existing and Newly Proposed Models for Creep Deformation and Life Prediction of Si3N4 written by J-L Ding and published by . This book was released on 1994 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper summarizes recent experimental results, obtained at Oak Ridge National Laboratory (ORNL), on creep behavior and creep rupture of a commercial grade of Si3N4 ceramic in the temperature range of 1150°C to 1300°C. A uniaxial model capable of describing the behavior under general thermomechanical loading is introduced and compared with existing models. An exploratory extension of the new model to a multiaxial form is then discussed. Issues are also discussed concerning the standardization of data analysis methodology and future research needs in the area related to development of creep database and life prediction methodology for high temperature structural ceramics.
Download or read book Advanced Ceramic Matrix Composites written by Edward R. Generazio and published by CRC Press. This book was released on 1995-12-14 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: Advanced ceramic composites are the focus of intense research and development today because these materials offer a unique mix of properties that make them useful and economical for major engineering applications. As part of this R&D effort, new tools for characterization, evaluation and testing have been developed and are in current use. This book brings together leading materials researchers to report on these developments. In-depth reports cover evaluation and test methods as they relate to the design of specific advanced ceramic composite materials and their applications. The reports are supplemented with extensive test result data and illustrated with numerous micrographs and schematics.

Available in PDF, EPUB and Kindle. Book excerpt: Several ceramic parts have already proven their suitability for serial application in automobile engines in very impressive ways, especially in Japan, the USA and in Germany. However, there is still a lack of economical quality assurance concepts. Recently, a new generation of ceramic components, for the use in energy, transportation and environment systems, has been developed. The efforts are more and more system oriented in this field. The only possibility to manage this complex issue in the future will be interdisciplinary cooperation. Chemists, physicists, material scientists, process engineers, mechanical engineers and engine manufacturers will have to cooperate in a more intensive way than ever before. The R&D activities are still concentrating on gas turbines and reciprocating engines, but also on brakes, bearings, fuel cells, batteries, filters, membranes, sensors and actuators as well as on shaping and cutting tools for low expense machining of ceramic components. This book summarizes the scientific papers of the 7th International Symposium "Ceramic Materials and Components for Engines". Some of the most fascinating new applications of ceramic meterials in energy, transportation and environment systems are presented. The proceedings shall lead to new ideas for interdisciplinary activities in the future.
