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. 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 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.

Download or read book High Temperature Mechanical Behavior of Ceramic-Matrix Composites written by Longbiao Li. This book was released on 2021-07-06. Available in PDF, EPUB and Kindle. Book excerpt: High Temperature Mechanical Behavior of Ceramic-Matrix Composites Covers the latest research on the high-temperature mechanical behavior of ceramic-matrix composites Due to their high temperature resistance, strength and rigidity, relatively light weight, and corrosion resistance, ceramic-matrix composites (CMCs) are widely used across the aerospace and energy industries. As these advanced composites of ceramics and various fibers become increasingly important in the development of new materials, understanding the high-temperature mechanical behavior and failure mechanisms of CMCs is essential to ensure the reliability and safety of practical applications. High Temperature Mechanical Behavior of Ceramic-Matrix Composites examines the behavior of CMCs at elevated temperature—outlining the latest developments in the field and presenting the results of recent research on different CMC characteristics, material properties, damage states, and temperatures. This up-to-date resource investigates the high-temperature behavior of CMCs in relation to first matrix cracking, matrix multiple cracking, tensile damage and fracture, fatigue hysteresis loops, stress-rupture, vibration damping, and more. This authoritative volume: Details the relationships between various high-temperature conditions and experiment results Features an introduction to the tensile, vibration, fatigue, and stress-rupture behavior of CMCs at elevated temperatures Investigates temperature- and time-dependent cracking stress, deformation, damage, and fracture of fiber-reinforced CMCs Includes full references and internet links to source material Written by a leading international researcher in the field, High Temperature Mechanical Behavior of Ceramic-Matrix Composites is an invaluable resource for materials scientists, surface chemists, organic chemists, aerospace engineers, and other professionals working with CMCs.
