Available in PDF, EPUB and Kindle. Book excerpt: This Memorandum contains the resu a study of cumulative fatigue damage. It shows that there are certain key assumptions which can be identi fied in current theories. These assumptions determine general trends in the structural weight required to provide a satisfactory fatigue life when a particular theory is used for fatigue-preventive design of a flight structure. The key assuittions have to do with the way fatigue damage is assumed to occur at different stress amplitudes when they are applied alone and when they are mixed with other stress ampli tudes (as is the case in aircraft).

Available in PDF, EPUB and Kindle. Book excerpt: Cumulative fatigue damage analysis plays an important role in fatigue life prediction of components and structures which are subjected to field loading histories. Understanding of cumulative damage mechanisms is essential since it provides the necessary physical bases for modeling the cumulative damage process. A damage measure that can reflect and quantify the real damage state the material undergoes is also a key issue for successful modeling of cumulative fatigue damage. This review paper provides a comprehensive overview of research activities highlighting the recent findings and progress on phenomenological observations and mechanisms, as well as quantification measures of cumulative fatigue damage. Depending on the definition of failure or the characteristics of failure experienced in a material, the effectiveness of a damage parameter could vary from case to case. Many damage parameters have been proposed and many of them are in use. Those to be reviewed are sorted into categories of metallurgical parameters, surface crack quantifications, mechanical measures, and physical parameters. Early studies on cumulative damage mechanisms and quantifying measures are reviewed only briefly, since they have been covered in the existing literature.

This book was released on 2013-03-04 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mechanical Vibration and Shock Analysis, Second Edition Volume 4: Fatigue Damage Fatigue damage in a system with one degree of freedom is one of the two criteria applied when comparing the severity of vibratory environments. The same criterion is also employed for a specification representing the effects produced by the set of vibrations imposed in a real-world environment. In this volume, which is devoted to the calculation of fatigue damage, the author explores the various hypotheses and models used to describe the behavior of material suffering fatigue and the laws of fatigue accumulation. He also considers the methods of counting response peaks, which are used to establish a histogram when it is impossible to use the probability density of the peaks obtained with a Gaussian signal. The expressions for mean damage and its standard deviation are established and other hypotheses are tested. The Mechanical Vibration and Shock Analysis five-volume series has been written with both the professional engineer and the academic in mind. Christian Lalanne explores every aspect of vibration and shock, two fundamental and extremely significant areas of mechanical engineering, from both a theoretical and practical point of view. The five volumes cover all the necessary issues in this area of mechanical engineering. The theoretical analyses are placed in the context of both the real world and the laboratory, which is essential for the development of specifications.

Book excerpt: About the Series: This important new series of five volumes has been written with both the professional engineers and the academic in mind. Christian Lalanne explores every aspect of vibration and shock, two fundamental and crucially important areas of mechanical engineering, from both the theoretical and practical standpoints. As all products need to be designed to withstand the environmental conditions to which they are likely to be subjected, prototypes must be verified by calculation and laboratory tests, the latter according to specifications from national or international standards. The concept of tailoring the product to its environment has gradually developed whereby, from the very start of a design project, through the to the standards specifications and testing procedures on th e prototype, the real environment in which the product being tested will be functioning is taken into account. The five volumes of Mechanical Shock and Vibration cover all the issues that need to be addressed in this area of mechanical engineering. The theoretical analyses are placed in the context of the real world and of laboratory tests - essential for the development of specifications. Volume IV: Fatigue Damage Fatigue damage in a system with one degree of freedom is one of the two criteria applied when comparing the severity of vibratory environments. The same criterion is also employed for a specifciation representing the effects produced by the set of vibrations imposed in a real environment.

This book was released on 2015 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fatigue failure is one of the most common type of failures when a load bearing component or structure is subjected to constant or variable amplitude cyclic loading. Material fatigue behavior under a given variable amplitude loading program could be evaluated both experimentally (fatigue testing) and analytically (cumulative fatigue damage rules). As fatigue testing is often a costly and time consuming method, cumulative fatigue damage models are commonly used for fatigue life prediction analysis. The main objective of this study was to investigate applicability of the commonly used Linear Damage Rule (LDR) for cumulative fatigue damage analysis of metallic materials with different cyclic softening/hardening deformation behaviors. LDR and five non-linear cumulative damage models were employed to predict fatigue life of several variable amplitude loading histories without presence of mean stress. These models were implemented in conjunction with conventional fatigue-life curves (strain-life and stress-life curves). In addition, LDR was also applied with SWT-life curve (a parameter which includes both strain and stress values of loading events). For the purpose of cumulative fatigue damage analysis, variable amplitude loading experimental results (in form of step loading, periodic overloading and block loading) of 16 metallic materials were used from the literature. For the materials with strong cyclic deformation behavior, it is shown that LDR with SWT approach leads to similar or even more accurate fatigue life predictions than any of the studied non-linear damage models. However, for the materials without considerable amount of cyclic hardening or softening, non-linear damage models performed relatively better than LDR with either SWT approach or conventional approach. Moreover, fatigue properties of materials fabricated with Selective Laser Melting (SLM) and Electron Beam Melting (EBM) processes (two common AM processes) were also reviewed based on fatigue data from the literature. To apply cumulative fatigue damage models for these materials, some recommendations are made based on the performance of cumulative fatigue damage models for the traditional-fabricated metallic materials. However, the accuracy of the proposed approach needs to be validated by variable amplitude loading experimental results, which are not currently available in the literature or in the open access databases.

Download or read book Introduction to Thermodynamics of Mechanical Fatigue written by Michael M. Khonsari and published by CRC Press. This book was released on 2012-09-17 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fatigue is probabilistic in nature and involves a complex spectrum of loading history with variable amplitudes and frequencies. Yet most available fatigue failure prediction methods are empirical and concentrate on very specific types of loading. Taking a different approach, Introduction to Thermodynamics of Mechanical Fatigue examines the treatment of fatigue via the principles of thermodynamics. It starts from the premise that fatigue is a dissipative process and must obey the laws of thermodynamics. In general, it can be hypothesized that mechanical degradation is a consequence of irreversible thermodynamic processes. This suggests that entropy generation offers a natural measure of degradation. An Entropic Approach to Fatigue and Degradation Drawing on recent cutting-edge research and development, the authors present a unified entropic approach to problems involving fatigue. They introduce the fundamentals of fatigue processes and explore a wide range of practical engineering applications. Fundamental Concepts and Methodologies The book reviews commonly observed failure modes, discusses how to analyze fatigue problems, and examines the deformation characteristics of a solid material subjected to fatigue loading. It also looks at how to use thermodynamics to determine the onset of fatigue failure. In addition, the book presents methodologies for improving fatigue life and for accelerated fatigue testing. Learn How to Apply the Entropic Approach to Fatigue Problems Comprehensive and well organized, this work helps readers apply powerful thermodynamics concepts to effectively treat fatigue problems at the design stage. It offers an accessible introduction to a new and exciting area of research in the field of fatigue failure analysis.

Download or read book Fatigue of Metallic Materials written by M. Klesnil and published by Elsevier. This book was released on 1992-04-13 with total page 274 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book reviews problems in the mechanical behaviour of cyclically loaded metallic materials, primarily with regard to the nature of the fatigue process. The first edition of the book appeared in 1980. The present second edition represents a revised form of the original book and also covers recent developments in the field. As the book focuses on physical-metallurgical aspects, it occupies a unique and important position in the technical literature, which has so far been devoted mainly to engineering metal fatigue problems and their technical solution in specific practical cases. The book provides a compact review of current knowledge on physical metallurgical processes that accompany and affect the fatigue of metallic materials, and also presents the background for applying the new results to practical designing and to the selection of materials in engineering practice. The authors present an updated review of results from countries both in the east and the west and cover a relatively large field in a concise manner. The work will be of value to research workers and students following advanced and post-graduate courses in the fields of materials science and mechanical engineering.
