Book excerpt: This is the first edition of the Durability Design Handbook. Objectives of this handbook are to: 1) summarize and interpret the essential USAF durability design requirements for metallic airframes; 2) provide durability analysis criteria for economic life and durability-critical parts; 3) provide state-of-the-art durability analysis concepts and methods for determining the initial fatigue quality of fastener holes, the probability of distribution of service time to reach any specified crack size; 4) provide guidelines and design data for implementing the durability methodology and for assisting contractor and USAF personnel in complying with the intent of the durability specifications for metallic airframes. This document, loosely called a "Handbook", provides guidelines, concepts, analytical tools, and the framework for incorporating future durability methodology advancements and design data.

Book Synopsis Problems in Service Life Prediction of Building and Construction Materials by : L.W. Masters
Download or read book Problems in Service Life Prediction of Building and Construction Materials written by L.W. Masters and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 289 pages. Available in PDF, EPUB and Kindle. Book excerpt: Degradation, the chemical/physical response of building and con struction materials exposed to in-service environments, must be predicted prior to their installation in structures if materials are to be effectively selected, used and maintained. These assessments of materials degradation require that methods be available to aid prediction of service life. The objectives of building materials science are a) to charac terize and categorize materials, b) to predict, preferably in a mathematical sense, material or component response including expected service life, and c) to make improvements in material response through improvements in design, formulation, processing or specification. For building and construction materials, continued progress has been made towards objective (a), but little progress has been made towards objectives (b) and (c). Of these, the mathematical prediction of service life appears to be of greater importance, because, if general approaches or models having application to a wide range of building and construction materials can be identi fied, then the categorization, selection, use and improvement of materials can proceed in a systematic manner. Researchers in advanced technologies, such as aerospace, nuclear, electronics and medicine, have apparently been more successful than researchers in building and construction technology in responding to the need for reliable predictions of service life.
Book Synopsis Stochastic Crack Propagation with Applications to Durability and Damage Tolerance Analyses by : J. N. Yang
Download or read book Stochastic Crack Propagation with Applications to Durability and Damage Tolerance Analyses written by J. N. Yang and published by . This book was released on 1985 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: Various stochastic models for fatigue crack propagation under either constant amplitude or spectrum loadings have been investigated. These models are based on the assumption that the crack growth rate is a lognormal random process, including the general lognormal random process, lognormal white noise process, lognormal random variable, and second moment approximations, such as Weibull, gamma, lognormal and Gaussian closure approximations. Extensive experimental data have been used for the correlation study with various stochastic models. These include fastener hole specimens under fighter or bomber spectrum laodings and center-cracked specimens under constant amplitude loads. The data sets for the fastener hole specimens cover adequately different loading conditions, environments, load transfers and crack size range. It is shown that the white noise process is definitely not a valid model for fatigue crack propagation.

Book Synopsis Durability Methods Development by : S. D. Manning
Download or read book Durability Methods Development written by S. D. Manning and published by . This book was released on 1979 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: A critical evaluation of three analytical approaches is made to determine their applicability and/or potential for analytically assuring airframe durability during the design stage. A suitable analytical format for quantifying durability damage is developed based on U.S. Air Force durability design specifications and durability analysis needs. Air Force durability requirements are briefly reviewed and discussed. Three potential approaches for durability damage analysis are conceptually evaluated and discussed: (1) Conventional Fatigue Analysis (Palmgren-Miner Rule); (2) Deterministic Crack Growth Approach; and (3) Probabilistic Crack Growth Approach. The resulting evaluation provides the prerequisite work needed to develop a durability analysis methodology. The probabilistic crack growth approach is found to be the most promising for developing the durability analysis methodology under Phase I.
Book Synopsis Structural Integrity of Aging Airplanes by : Satya N. Atluri
Download or read book Structural Integrity of Aging Airplanes written by Satya N. Atluri and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 492 pages. Available in PDF, EPUB and Kindle. Book excerpt: The emergence of civil aviation as a means of mass transportation is primarily due to the large scale construction of jet airplanes in the past 30 years or so. A large number of these jet airplanes is currently operating at or beyond their designed fatigue lives. Thus, the structural integrity of these aging airplanes has become an issue of major concern to all nations of the world. To bring the needed technical and research focus on the issues involved in the life-enhancement and safety-assurance of aging airplanes, the Federal Aviation Administration sponsored a symposium in Atlanta, GA, USA, during 20-22 March 1990. This symposium, under the title "International Symposium on Structural Integrity of Aging Airplanes· was organized jointly be the Georgia Institute of Technology (Center for Computational Mechanics) and the Transportation Systems Center (Cambridge, MA) of the U.S. Department of Transportation. Industrial and academic experts from several countries in North America, Europe and Asia, were invited to discuss their experiences and proposed solutions. This monograph contains the original papers that represent the expanded and edited versions of the talks presented at this symposium. This book aims to bring the collective experience, from across the world, with problems related to the structural integrity of aging airplanes to the attention of the professional and research community at large - in the hope that it may stimulate further fruitful research on this important topic of global concern.

This book was released on 2012-12-06 with total page 600 pages. Available in PDF, EPUB and Kindle. Book excerpt: The IUTAM Symposium on Probabilistic Methods in the Mechanics of Solids and Structures, dedicated to the memory of Waloddi Weibull, was held in Stockholm, Sweden, June 19-21, 1984, on the initiative of the Swedish National Committee for Mech anics and the Aeronautical Research Institute of Sweden, FFA. The purpose of the symposium was to bring together mathema ticians that develop the theory of stochastic processes and methods for reliability analysis, with engineers that apply these theories and methods to model loads, strengths and structures for the advancement of structural safety. Waloddi Weibull was a pioneer in this field with his many publi cations from the thirties until his death in 1979. He also took an active part in the formation of the International Union of Theoretical and Applied Mechanics during the forties, and subsequently initiated foundation of the Swedish National Committee for Mechanics, through which Sweden joined IUTAM as a member. 116 participants from 21 countries attended the symposium, and 55 invited papers were presented in 7 scientific sessions.
