This book was released on 2002-04-24 with total page 470 pages. Available in PDF, EPUB and Kindle. Book excerpt: A daring, original approach to understanding and predicting the mechanical behavior of materials "Damage is an abstraction . . . Strength is an observable, an independent variable that can be measured, with clear and familiar engineering definitions." -from the Preface to Damage Tolerance and Durability of Material Systems Long-term behavior is one of the most challenging and important aspects of material engineering. There is a great need for a useful conceptual or operational framework for measuring long-term behavior. As much a revolution in philosophy as an engineering text, Damage Tolerance and Durability of Material Systems postulates a new mechanistic philosophy and methodology for predicting the remaining strength and life of engineering material. This philosophy associates the local physical changes in material states and stress states caused by time-variable applied environments with global properties and performance. There are three fundamental issues associated with the mechanical behavior of engineering materials and structures: their stiffness, strength, and life. Treating these issues from the standpoint of technical difficulty, time, and cost for characterization, and relationship to safety, reliability, liability, and economy, the authors explore such topics as: * Damage tolerance and failure modes * Factors that determine composite strength * Micromechanical models of composite stiffness and strength * Stiffness evolution * Strength evolution during damage accumulation * Non-uniform stress states * Lifetime prediction With a robust selection of example applications and case studies, this book takes a step toward the fulfillment of a vision of a future in which the prediction of physical properties from first principles will make possible the creation and application of new materials and material systems at a remarkable cost savings.
Book Synopsis Damage Tolerance of Metallic Aircraft Structures by : Sérgio M. O. Tavares
Download or read book Damage Tolerance of Metallic Aircraft Structures written by Sérgio M. O. Tavares and published by Springer. This book was released on 2018-08-06 with total page 117 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a state-of-the-art review of the fail-safe and damage tolerance approaches, allowing weight savings and increasing aircraft reliability and structural integrity. The application of the damage tolerance approach requires extensive know-how of the fatigue and fracture properties, corrosion strength, potential failure modes and non-destructive inspection techniques, particularly minimum detectable defect and inspection intervals. In parallel, engineering practice involving damage tolerance requires numerical techniques for stress analysis of cracked structures. These evolved from basic mode I evaluations using rough finite element approaches, to current 3D modeling based on energetic approaches as the VCCT, or simulation of joining processes. This book provides a concise introduction to this subject.

This book was released on 2018-08-27 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aerospace vehicles are designed to be durable and damage tolerant. Durability is largely an economic life-cycle design consideration whereas damage tolerance directly addresses the structural airworthiness (safety) of the vehicle. However, both durability and damage tolerance design methodologies must address the deleterious effects of changes in material properties and the initiation and growth of microstructural damage that may occur during the service lifetime of the vehicle. Durability and damage tolerance design and certification requirements are addressed for commercial transport aircraft and NASA manned spacecraft systems. The state-of-the-art in advanced design and analysis methods is illustrated by discussing the results of several recently completed NASA technology development programs. These programs include the NASA Advanced Subsonic Technology Program demonstrating technologies for large transport aircraft and the X-33 hypersonic test vehicle demonstrating technologies for a single-stage-to-orbit space launch vehicle.Harris, Charles E. and Starnes, James H., Jr. and Shuart, Mark J.Langley Research CenterAIRCRAFT RELIABILITY; DAMAGE; DESIGN ANALYSIS; MICROSTRUCTURE; LIFE (DURABILITY); AEROSPACE VEHICLES; CERTIFICATION; COMMERCIAL AIRCRAFT; ECONOMICS; HYPERSONIC VEHICLES; X-33 REUSABLE LAUNCH VEHICLE...

Book Synopsis Aging of U.S. Air Force Aircraft by : National Research Council
Download or read book Aging of U.S. Air Force Aircraft written by National Research Council and published by National Academies Press. This book was released on 1997-09-30 with total page 124 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many of the aircraft that form the backbone of the U.S. Air Force operational fleet are 25 years old or older. A few of these will be replaced with new aircraft, but many are expected to remain in service an additional 25 years or more. This book provides a strategy to address the technical needs and priorities associated with the Air Force's aging airframe structures. It includes a detailed summary of the structural status of the aging force, identification of key technical issues, recommendations for near-term engineering and management actions, and prioritized near-term and long-term research recommendations.
Book Synopsis Durability Methods Development by : S. D. Manning

Book excerpt: A summary is presented of an analytical methodology developed to meet USAF durability requirements. Details are given in four companion volumes. Analytical approaches that are currently used or have potential to be used to determine economic life are surveyed. Results of a structural survey of durability problems experienced at USAF ALC's are summarized. Durability critical parts criteria and economic life criteria are discussed. An analytical method to determine the crack population in a structure as a function of service time is presented. Fastener-hole cracking is the basic form of damage analyzed. Representations of initial quality and growth of small cracks are discussed. The effect of inspection and repair on the distribution of cracks is included.

Available in PDF, EPUB and Kindle. Book excerpt: Simplified predictive methods and models ("theory") to evaluate fiber/polymermatrix composite material for determining structural durability and damage tolerance are described. This "theory" includes equations for: (1) fatigue and fracture of composites without and with defects; (2) impact resistance and residual strength after impact; (3) thermal fatigue; and (4) combined stress fatigue. Several examples are included to illustrate applications of the "theory" and to identify significant parameters and sensitivities. Comparisons with limited experimental data are made.
