Book excerpt: Baseline fatigue crack growth data at R = 0 and mechanical property data have been generated on 66 different rail materials which are in service on U.S. railroads. These data are evaluated, along with metallurgical variables such as chemical composition and microstructure, in an attempt to develop a correlation of mechanical and metallurgical factors affecting crack behavior in rail steels. The ultimate objective of this effort is the development of a rail failure model to enable the determination of safe inspection intervals, through prediction of fatigue crack growth in rail under service loading.

Download or read book The Effect of Grain Boundary Ferrite on Fatigue Crack Propagation in Pearlitic Rail Steels written by GJ. Fowler and published by . This book was released on 1978 with total page 2 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fatigue crack growth has been examined in pearlitic rail steels to determine the effect of grain boundary ferrite and nonmetallic inclusions on the rates of crack propagation under Mode I loading at ambient temperature. The influence of alternating and maximum stress intensity on fatigue crack propagation in these materials has also been evaluated. The data were obtained using single-edge notch specimens machined from the head of rails and the web of wheels. Cyclic loading was performed on a hydraulic test machine at various R ratios.

This book was released on 1993-07-31 with total page 476 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume presents a collection of papers on the theme of rail integrity, which were presented at a meeting in Delft from 24--26th June, 1992. Rolling contact fatigue is a failure mode which is increasingly being recognised as a threat to the reliability of modern heavy freight and high speed railway systems. These papers describe the current understanding of the problem and what rail steel technology and maintenance procedures have to offer to combat it.

Available in PDF, EPUB and Kindle. Book excerpt: The microstructure-mechanical properties relationships, fracture toughness, fatigue crack growth and fracture surface morphology of J6 bainitic, manganese, and pearlitic rail steels were studied. Microstructure-mechanical properties correlation of the three rail steels under consideration revealed that the bainitic rail steel has the highest mechanical properties as compared with austenitic manganese steel (AMS) and pearlitic rail steels. AMS shows very few signs of being work hardened or toughened, which usually increases the mechanical properties of the material. In pearlite, the microstructure has more detailed features that contribute to its mechanical properties. The bainitic steel has more alloying elements that when mixed, create so many dislocations that the dislocations cannot move against each other. This is where bainitic steel derives its strength. Fracture toughness analysis (KIc) of the three rail steels, namely bainitic, manganese and pearlitic was performed. A valid KIc was determined for the pearlitic and bainitic steels based on the American Society of Testing and Materials (ASTM) E399 criteria.

Download or read book Fatigue of Structures and Materials written by J. Schijve and published by Springer Science & Business Media. This book was released on 2008-12-16 with total page 627 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fatigue of structures and materials covers a wide scope of different topics. The purpose of the present book is to explain these topics, to indicate how they can be analyzed, and how this can contribute to the designing of fatigue resistant structures and to prevent structural fatigue problems in service. Chapter 1 gives a general survey of the topic with brief comments on the signi?cance of the aspects involved. This serves as a kind of a program for the following chapters. The central issues in this book are predictions of fatigue properties and designing against fatigue. These objectives cannot be realized without a physical and mechanical understanding of all relevant conditions. In Chapter 2 the book starts with basic concepts of what happens in the material of a structure under cyclic loads. It illustrates the large number of variables which can affect fatigue properties and it provides the essential background knowledge for subsequent chapters. Different subjects are presented in the following main parts: • Basic chapters on fatigue properties and predictions (Chapters 2–8) • Load spectra and fatigue under variable-amplitude loading (Chapters 9–11) • Fatigue tests and scatter (Chapters 12 and 13) • Special fatigue conditions (Chapters 14–17) • Fatigue of joints and structures (Chapters 18–20) • Fiber-metal laminates (Chapter 21) Each chapter presents a discussion of a speci?c subject.

Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this Handbook is to provide a review of the knowledge and experiences in the field of fatigue fracture mechanics. It is well-known that engineering structures can fail due to cyclic loading. For instance, a cyclically time-varying loading reduces the structure strength and can provoke a fatigue failure consisting of three stages: (a) crack initiation (b) crack propagation and (c) catastrophic failure. Since last century many scientists have tried to understand the reasons for the above-mentioned failures and how to prevent them. This Handbook contains valuable contributions from leading experts within the international scientific community and covers many of the important problems associated with the fatigue phenomena in civil, mechanical and nuclear engineering.

Download or read book Problems of Fracture Mechanics and Fatigue written by E.E. Gdoutos and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 573 pages. Available in PDF, EPUB and Kindle. Book excerpt: On Fracture Mechanics A major objective of engineering design is the determination of the geometry and dimensions of machine or structural elements and the selection of material in such a way that the elements perform their operating function in an efficient, safe and economic manner. For this reason the results of stress analysis are coupled with an appropriate failure criterion. Traditional failure criteria based on maximum stress, strain or energy density cannot adequately explain many structural failures that occurred at stress levels considerably lower than the ultimate strength of the material. On the other hand, experiments performed by Griffith in 1921 on glass fibers led to the conclusion that the strength of real materials is much smaller, typically by two orders of magnitude, than the theoretical strength. The discipline of fracture mechanics has been created in an effort to explain these phenomena. It is based on the realistic assumption that all materials contain crack-like defects from which failure initiates. Defects can exist in a material due to its composition, as second-phase particles, debonds in composites, etc. , they can be introduced into a structure during fabrication, as welds, or can be created during the service life of a component like fatigue, environment-assisted or creep cracks. Fracture mechanics studies the loading-bearing capacity of structures in the presence of initial defects. A dominant crack is usually assumed to exist.
