Book Synopsis High Temperature Mechanical Behaviour of Ceramic Composites by : Karl Jakus
Download or read book High Temperature Mechanical Behaviour of Ceramic Composites written by Karl Jakus. This book was released on 1995-06-28. 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. Shanti Nair is Associate Professor at the Department of Mechanical Engineering at the University of Massachusetts at Amherst. Karl Jakus is Professor at the University of Massachusetts at Amherst.

Book Synopsis High Temperature Ceramic Matrix Composites by : Walter Krenkel
Download or read book High Temperature Ceramic Matrix Composites written by Walter Krenkel. This book was released on 2001. Available in PDF, EPUB and Kindle. Book excerpt: The extreme high temperature stability and damage tolerance of materials and components required for space, terrestrial, energetic and many other applications can only be achieved by ceramic materials. All over the world research is going on to develop ceramics with quasiductile behaviour. The materials with the highest potential for high temperature applications are fibre reinforced ceramic matrix composites (CMC). The international conference HT-CMC 4 in Munich will continue the tradition of its successful predecessor meetings held in Bordeaux (France, 1993), Santa Barbara (USA, 1995) and Osaka (Japan, 1998). This conference series has been recognized as the central meeting event in high temperature CMC science and technology and demonstrates the great interest in research and development on reinforced ceramics. The Proceedings of this conference will therefore be a valuable reference for every materials scientist or engineer involved in this field of high-tech materials development.

Book Synopsis Time-Dependent Mechanical Behavior of Ceramic-Matrix Composites at Elevated Temperatures by : Longbiao Li
Download or read book Time-Dependent Mechanical Behavior of Ceramic-Matrix Composites at Elevated Temperatures written by Longbiao Li. This book was released on 2020-04-18. Available in PDF, EPUB and Kindle. Book excerpt: This book investigates the time-dependent behavior of fiber-reinforced ceramic-matrix composites (CMCs) at elevated temperatures. The author combines the time-dependent damage mechanisms of interface and fiber oxidation and fracture with the micromechanical approach to establish the relationships between the first matrix cracking stress, matrix multiple cracking evolution, tensile strength, tensile stress-strain curves and tensile fatigue of fiber-reinforced CMCs and time. Then, using damage models of energy balance, the fracture mechanics approach, critical matrix strain energy criterion, Global Load Sharing criterion, and hysteresis loops he determines the first matrix cracking stress, interface debonded length, matrix cracking density, fibers failure probability, tensile strength, tensile stress-strain curves and fatigue hysteresis loops. Lastly, he predicts the time-dependent mechanical behavior of different fiber-reinforced CMCs, i.e., C/SiC and SiC/SiC, using the developed approaches, in order to reduce the failure risk during the operation of aero engines. The book is intended for undergraduate and graduate students who are interested in the mechanical behavior of CMCs, researchers investigating the damage evolution of CMCs at elevated temperatures, and designers responsible for hot-section CMC components in aero engines.

Book Synopsis High Temperature Micromechanics and Mechanisms of Damage and Failure in Advanced Ceramic-Matrix Composites by :
Download or read book High Temperature Micromechanics and Mechanisms of Damage and Failure in Advanced Ceramic-Matrix Composites written by . This book was released on 2000. Available in PDF, EPUB and Kindle. Book excerpt: In this project, research efforts have been made to address some of the most critical and complex issues on high-temperature damage, degradation and failure of advanced composites. For the convenience of program planning and execution, the research as been formulated in the form of several interrelated technical tasks with distinct focuses. In the study of high-temperature ceramic-matrix the following tasks have been conducted: (1) High-temperature fiber/matrix interface properties and failure mechanics; (2) High-temperature micromechanics theories for thermoelastic constitutive equations for whisker-reinforced ceramic composites with large temperature traverse; (3) High-temperature creep deformation and micromechanics modeling of inelastic composite constitutive properties with composite microstructure and damage, and (4) High-temperature toughening mechanisms, and mechanics of crack growth fracture. For the high-temperature polymer-matrix composite study, the following thermomechanics issues with internal and external damage have been addressed: (1) thermal oxidation reaction and stability at elevated temperatures; (2) chemical and physical aging in extreme thermal environments; (3) microstructure changes and property degradation associated with aging at elevated temperatures; and (4) long-term thermomechanical creep and associated damage modes.
