Residual Stress in Rails by O. Orringer,J. Orkisz,Zdzislaw Swiderski Pdf

Rail integrity is a current application of engineering fracture mechanics at a practical level. Although railroad rails have been manufactured and used for more than a century, it is only in the last ten years that the effects of their crack propagation and fracture characteristics have been considered from a rational viewpoint. The J,Jractical objectives are to develop damage tolerance ~delines for rail inspection and to improve the fracture resistance of new rail productiOn. Rail fatigue crack propagation rates and fracture resistance are strongly influenced by residual stresses, which are introduced into the rail both during proouction and in service. Therefore, the rail residual stress field must be well understood before fracture mechanics can be usefully applied to the subject of rail integrity. The three-dintensional character of rail and its stress fields make it essential to apply both experimental and analytical methods in order to twderstand the effects of pro duction and service variables on residual stress and the effects of the stress on fatigue crack propagation and fracture. This volume brings to~ether field observations and experimental stress analysis of railroad rails in the Umted States and Europe. The ongoing search for an efficient and accurate technique is emphasized. A companion volume brings together several analytical investigations, based on advanced compu tational mechanics methods, for correlation of the experimental data as well as eval uation of the effects of residual stress on rail integrity.

Practical Residual Stress Measurement Methods by Gary S. Schajer Pdf

An introductory and intermediate level handbook written in pragmatic style to explain residual stresses and to provide straightforward guidance about practical measurement methods. Residual stresses play major roles in engineering structures, with highly beneficial effects when designed well, and catastrophic effects when ignored. With ever-increasing concern for product performance and reliability, there is an urgent need for a renewed assessment of traditional and modern measurement techniques. Success critically depends on being able to make the most practical and effective choice of measurement method for a given application. Practical Residual Stress Measurement Methods provides the reader with the information needed to understand key residual stress concepts and to make informed technical decisions about optimal choice of measurement technique. Each chapter, written by invited specialists, follows a focused and pragmatic format, with subsections describing the measurement principle, residual stress evaluation, practical measurement procedures, example applications, references and further reading. The chapter authors represent both international academia and industry. Each of them brings to their writing substantial hands-on experience and expertise in their chosen field. Fully illustrated throughout, the book provides a much-needed practical approach to residual stress measurements. The material presented is essential reading for industrial practitioners, academic researchers and interested students. Key features: • Presents an overview of the principal residual stress measurement methods, both destructive and non-destructive, with coverage of new techniques and modern enhancements of established techniques • Includes stand-alone chapters, each with its own figures, tables and list of references, and written by an invited team of international specialists

International Conference on Residual Stresses by G. Beck,S. Denis,A. Simon Pdf

Residual stresses are always introduced in materials when they are produced, or when they undergo non-uniform plastic deformation during use. The circumstances that can cause residual stresses are therefore numerous. Residual stresses exist in all materials and, depending on their distribution, can playa beneficial role (for example, compressive surface stress) or have a catastrophic effect, especially on fatigue behaviour and corrosion properties. The subject of residual stresses took form around 1970 with the development of methods to measure macroscopic deformations during the machining of materials or on an atomic scale by X-ray diffraction. These techniques have made considerable progress in the last 20 years. The meetings organized in several countries (Germany, France, Japan, etc. ) have largely contributed to this progress, aided by the numerous exchanges of information and knowledge to which they have given rise. Studies of the formation of residual stresses began more slowly, but have progressed with the emergence of increasingly realistic models of materials behaviour and with access to ever more powerful codes for numerical calculations. Two successive meetings for discussing this topic have been held in Europe. The first, held in 1982 in Nancy (France), consisted of 30 participants from 5 countries. The second was held in Linkoping (Sweden) in 1984, with 80 participants of 16 nationalities. It was decided to hold a first International Conference, ICRS, to address all aspects of the problem. Held in 1986 in Garmisch-Partenkirschen (FRG), it was an assembly of neady 300 participants from 21 countries.

Rail Quality and Maintenance for Modern Railway Operation by J.J. Kalker,D.F. Cannon,O. Orringer Pdf

In April 1990 a conference was held at the Cracow Institute of Technology, Cracow, Poland. The title of that conference was "Residual Stresses in Rails - Effects on Rail Integrity and Railroad Economics" and its themes were the measurement and prediction of residual stresses in rails, but, as the sub-title suggests, the intention was also to provide a link between research and its application to the practical railway world. At the Cracow conference there were 40 participants with 5 railways and 5 rail makers being represented and 25 papers were given. The Cracow conference was a success, and by March 1991 its off-spring, "The International Conference on Rail Quality and Maintenance for Modern Railway Operations", was conceived and birth was ultimately given in June 1992 at the Technical University, Delft. It turned out to be some baby, with 112 delegates from 24 countries taking part! As with its predecessor, the conference was to provide a forum for the exchange of ideas between research investigators, rail makers and railway engineers. A cursory examination of the list of participants suggests that about 57% were from the railway industry, 34% from universities and other research institutions and 9% from the steel industry. Bearing in mind that some of the railway industry participants were from their respective research and development organisations the balance of interests was about right.
