Download or read book Modeling of Crack Initiation and Growth in Solid Rocket Propellants Using Macromechanics and Micromechanics Theories written by James H. Lee and published by . This book was released on 1996-09-01 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: Modeling and simulation of crack initiation and propagation in solid rocket propellant materials were conducted using both the macromechanics approach and the micro/macromechanics approach. Due to their composition, the solid rocket propellant can be construed as particle reinforced composites. The macromechanics approach entailed a numerical simulation of a finite element model to predict the crack behavior based on the damage initiation, growth, and local saturation. Its results were then compared to the experimental data. In the simulation, it was assumed that a crack forms when a damage is saturated in a localized zone. The results from the simulation were quite comparable to the experimental results, validating the method of predicting crack initiation, growth, and arrest using the concept of damage growth and saturation. The second approach involved using a simplified micromechanical model and the damage mechanics being applied at the micromechanics level and the finite element analysis being done subsequently at the macromechanics level. In using this approach, the damage modes such as matrix cracking, interface debonding and particle cracking were explainable in an explicit fundamental manner. Several simulations were conducted using this approach including the cases of non- uniform particle distribution. The predicted results compared well with the experimental data.

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

Available in PDF, EPUB and Kindle. Book excerpt: Purdue University has played a leading role in providing the engineers who designed, built, tested, and flew the many aircraft and spacecraft that so changed human progress during the 20th century. It is estimated that Purdue has awarded 6% of all BS degrees in aerospace engineering, and 7% of all PhDs in the United States during the past 65 years. The University's alumni have led significant advances in research and development of aerospace technology, have headed major aerospace corporations and government agencies, and have established an amazing record for exploration of space. More than one third of all US manned space flights have had at least one crew member who was a Purdue engineering graduate (including the first and last men to step foot on the moon). The School of Aeronautics & Astronautics was founded as a separate school within the College of Engineering at Purdue University in 1945. The first edition of this book was published in 1995, at the time of the school's 50th anniversary. This corrected and expanded second edition brings the school's illustrious history up to date, and looks to Purdue's future in the sky and in space.

This book was released on 1999 with total page 450 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hardbound. Solid mechanics is a basic scientific discipline which provides the theoretical foundation, experimental support, solution methodology and computational tools for analysis, design, construction, manufacture, and behavior prediction in service of many devices, machines, materials, structures and large complex systems that are essential to the existence and progress of an advanced civilization. It is concerned with both manmade, natural and living solid objects, and with all aspects of their physical behavior that affect their function, integrity or service life expectancy.The contents of this volume offer examples of some of the activities that are currently at the forefront of solid mechanics research, and also illustrate the vast reach of the discipline and of its interactions with other science and engineering endeavors.
