Download or read book Fatigue Crack Growth Behavior and Life Predictions for 2219 T851 Aluminum Subjected to Variable Amplitude Loadings written by JB. Chang and published by . This book was released on 1981 with total page 25 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fatigue crack growth behavior of 2219-T851 aluminum is characterized for variable-amplitude loading conditions which include the single and periodic tensile or compressive overload, single tensile overload followed by a single compressive load, multiple tensile and compressive overloads, high-low or low-high block loading, and compression-compression loads followed by tension-tension loads. A load interaction model which accounts for the overload retardation and compressive load acceleration effects on fatigue crack growth lives is introduced. Fatigue crack growth analyses are performed on all test cases using a computer program which employs this load interaction model. Analytical predictions are correlated with the test data. Results show that this model adequately predicted fatigue crack growth behavior and fatigue crack lives for most of the test loading conditions to within ±30 percent.

Available in PDF, EPUB and Kindle. Book excerpt: This report presents the technical details of improved methods for predicting the load interaction effects on crack growth under flight spectrum loading developed in a research effort sponsored by the USAF. These include the cycle-by-cycle crack-growth prediction methods used in the detail design stage, the flight-by-flight crack-growth analysis method for individual aircraft tracking usage, and preliminary design trade-off studies.

Download or read book ASTM Fatigue Life Round Robin Predictions written by JB. Chang and published by . This book was released on 1984 with total page 19 pages. Available in PDF, EPUB and Kindle. Book excerpt: A series of round-robin predictions of fatigue crack life have been conducted since 1976 by ASTM Task Group E24.06.01 on Application of Fracture Data to Life Prediction. The primary objective of these round-robin exercises was to investigate (1) if the compact type (CT) specimen constant-amplitude fatigue-crack-growth-rate data could be used to predict the growth behavior and lives of part-through crack (PTC) specimens under constant amplitude loading, and (2) if center-crack-tension (CCT) specimen constant-amplitude fatigue-crack-growth-rate data could be used to predict the growth behavior and lives of CCT specimens subjected to variable amplitude and random spectrum loadings. Five sets of round-robin predictions were conducted on a total of 57 specimens that were made of three materials: 2219-T851 aluminum, 6Al-4V titanium, and 9Ni-4Co-0.2C steel. This paper summarizes the results of these round-robin analytical predictions and their correlations to test data.

Book excerpt: This volume contains the edited version of lectures and selected research contributions presented at the NATO ADVANCED STUDY INSTITUTE on ADVANCES IN FATIGUE SCIENCE AND TECHNOLOGY. held in Alvor. Portugal, 4th to 15th of April 1988. and organized by CEMUL - Center of Mechanics and Materials of The Technical University of Lisbon. The Institute was attended by 101 participants, including 15 lecturers. from 14 countries. The participants were leading scientists and engineers from universities, research institutions and industry. and also Ph.D~ students. Some participants presented papers during the Institute reporting the state-of-art of their research projects. All the sessions wel'e very active and quite extensive discussions on scientific aspects took place during the Institute. The Advanced Study Institute provided a forum for interaction among eminent scientists and engineers. from different schools of thought and young researchers. The Institute addressed the foundations and current state of the art of essential aspects related to fatigue science and technology, namely: Short Cracks, Metallurgical Aspects, Environmental Fatigue, Threshold Behaviour, Notch Behaviour. Creep and Fatigue Interactions at High Temperature, Multiaxial Fatigue, Low Cycle Fatigue, Methodology of Fatigue Testing, Variable Amplitude Fatigue, Fatigue of Advanced Materials. Elastic-Plastic Fatigue, and several engineering applications such as welded joints, energy systems, offshore structures, automotive industry, machine and engine components. This book is organized in three parts: Part I: Fundamentals of Fatigue Part II: Engineering Applications Part III: Research Contributions The research contributions covered most of the areas referred above.
