Book excerpt: The development of Silicon Carbide composite materials for structural applications in fusion energy systems is mainly motivated by the prospect that fusion power systems utilizing the material will have a much more favorable environmental impact. The research team at UCLA was the first to identify the potential advantages of SiC/SiC composite materials through early System Studies. Consequently, two three-year term grants have been awarded to the team, in order to focus on modeling the effects of irradiation on key properties that have been recognized by the community as fundamental to the successful development of the composite. Two main tasks, which are further subdivided into several subtasks each, have been pursued during the course of research during the period: December 1990 through November 1996. The first task deals with modeling the effects of irradiation on the dimensional stability of SiC. To achieve this goal, a substantial effort was launched for modeling the evolution of the microstructure under irradiation. Rate and Fokker-Planck theories have been advanced to model the complex multi-component system of SiC under irradiation. The effort has resulted in a deeper understanding of the interaction between displacement damage components, and transmutant helium gas atoms. Utilizing the methods of Molecular Dynamics (MD) and Monte Carlo (MC), the energetics of defects and the basic displacement mechanisms in SiC have been fully delineated. An advanced Fokker-Planck approach was formulated to determine the phase content and size distribution of damage microstructure in SiC. Finally, a rate theory model was developed and successfully applied to the experimental swelling data on SiC. In the second task, the authors investigated the mechanical behavior of SiC/SiC composites under the irradiation conditions of fusion reactors. The main focus of the second task has been on developing models for the micro-mechanics of cracks in the fiber reinforced matrix of the silicon carbide composite. The effects of irradiation on inducing inelastic deformations in the fiber and the matrix were emphasized. Brief reviews for the results of their research are given here, followed by copies of 26 journal publications resulting from the work supported under this grant.

Available in PDF, EPUB and Kindle. Book excerpt: The AFOSR oxidation-protected C-C composite program is focused on developing and verifying mathematical models predicting the thermomechanical properties of exposed carbon-carbon composites. These models will be utilized to make judgements on the merits of both current and future materials concepts for oxidation resistance. These efforts are focused on the understanding of the formation and growth of damage within these materials, and on the influence of oxidation protection constituents on the overall carbon-carbon material system. Models will be used to investigate the effects of inhibitors, microcrack patterns, fiber coatings, surface coatings and matrix replacements on effective thermomechanical properties of carbon-carbon materials. The result of these models will allow the quantification of effective crack management strategies to improve the overall performance of these materials. Parallel efforts in this program include an experimental portion for the quantification of microcracks within the material and a variety of thermomechanical tests on specimens with and without coatings and inhibitors. Different material systems will allow a full range of constituent and processing variables to be studied. Results of these experiments will be compared to the predictions of the mathematical models in order to suggest improved design methods for carbon. carbon material systems. ...

This book was released on 2020-04-18 with total page 373 pages. 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.

Download or read book Comprehensive Nuclear Materials written by and published by Elsevier. This book was released on 2020-07-22 with total page 4871 pages. Available in PDF, EPUB and Kindle. Book excerpt: Materials in a nuclear environment are exposed to extreme conditions of radiation, temperature and/or corrosion, and in many cases the combination of these makes the material behavior very different from conventional materials. This is evident for the four major technological challenges the nuclear technology domain is facing currently: (i) long-term operation of existing Generation II nuclear power plants, (ii) the design of the next generation reactors (Generation IV), (iii) the construction of the ITER fusion reactor in Cadarache (France), (iv) and the intermediate and final disposal of nuclear waste. In order to address these challenges, engineers and designers need to know the properties of a wide variety of materials under these conditions and to understand the underlying processes affecting changes in their behavior, in order to assess their performance and to determine the limits of operation. Comprehensive Nuclear Materials, Second Edition, Seven Volume Set provides broad ranging, validated summaries of all the major topics in the field of nuclear material research for fission as well as fusion reactor systems. Attention is given to the fundamental scientific aspects of nuclear materials: fuel and structural materials for fission reactors, waste materials, and materials for fusion reactors. The articles are written at a level that allows undergraduate students to understand the material, while providing active researchers with a ready reference resource of information. Most of the chapters from the first Edition have been revised and updated and a significant number of new topics are covered in completely new material. During the ten years between the two editions, the challenge for applications of nuclear materials has been significantly impacted by world events, public awareness, and technological innovation. Materials play a key role as enablers of new technologies, and we trust that this new edition of Comprehensive Nuclear Materials has captured the key recent developments. Critically reviews the major classes and functions of materials, supporting the selection, assessment, validation and engineering of materials in extreme nuclear environments Comprehensive resource for up-to-date and authoritative information which is not always available elsewhere, even in journals Provides an in-depth treatment of materials modeling and simulation, with a specific focus on nuclear issues Serves as an excellent entry point for students and researchers new to the field
