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.

This volume presents peer-reviewed contributions from the 10th International Conference on Experimental Vibration Analysis for Civil Engineering Structures (EVACES), held in Milan, Italy on August 30-September 1, 2023. The event brought together engineers, scientists, researchers, and practitioners, providing a forum for discussing and disseminating the latest developments and achievements in all major aspects of dynamic testing for civil engineering structures, including instrumentation, sources of excitation, data analysis, system identification, monitoring and condition assessment, in-situ and laboratory experiments, codes and standards, and vibration mitigation. The topics included but were not limited to: damage identification and structural health monitoring; testing, sensing and modeling; vibration isolation and control; system and model identification; coupled dynamical systems (including human–structure, vehicle–structure, and soil–structure interaction); and application of advanced techniques involving the Internet of Things, robot, UAV, big data and artificial intelligence.

This book is a collection of the latest research findings in such areas as networked multi-agent systems, co-design of communication and control, distributed control strategies that can cope with asynchrony between local loops, event-triggered control, modelling of network infrastructure, novel concepts of distributed control for networked and cyber-physical systems. The book contains the result of the latest research in the field of communication and control system design to support networked control systems with stringent real-time requirements. It introduces readers to research in the field of joint design of the control and communication protocol and presents the latest developments in the area of novel optimal control and scheduling designs under resource constraints. The book also covers the issues of creating emerging information and communication technologies for traffic estimation and control, connected and autonomous technology applications and modelling for commercial and shared vehicle operations. The reader will find information on emerging cyber-physical systems, networked multi-agent systems, large-scale distributed energy systems, as well as on real-time systems, safety and security systems. A significant block of studies is devoted to the topic of transitions towards electrification and automation of vehicles. Modern concepts of road infrastructure construction are described in detail in the presented research papers. Automotive industry professionals will be particularly interested in the sections on the novel mechanisms for medium access in multi-hop wireless networks with real-time requirements, optimal layering architecture and co-design for wireless communication. The book will be incredibly interesting for researchers interested in human–digital interfaces, industrial Internet of Things, artificial intelligence and machine learning.

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.

Annotation Examines the factors that contribute to overall steel deformation problems. The 27 articles address the effect of materials and processing, the measurement and prediction of residual stress and distortion, and residual stress formation in the shaping of materials, during hardening processes, and during manufacturing processes. Some of the topics are the stability and relaxation behavior of macro and micro residual stresses, stress determination in coatings, the effects of process equipment design, the application of metallo- thermo-mechanic to quenching, inducing compressive stresses through controlled shot peening, and the origin and assessment of residual stresses during welding and brazing.

Failure Analysis in Engineering Applications deals with equipment and machine design together with examples of failures and countermeasures to avoid such failures. This book analyzes failures in facilities or structures and the ways to prevent them from happening in the future. The author describes conventional terms associated with failure or states of failure including the strength of materials, as well as the procedure in failure analysis (materials used, design stress, service conditions, simulation, examination of results). The author also describes the mechanism of fatigue failure and prediction methods to estimate the remaining life of affected structures. The author cites some precautions to be followed in actual failure analysis such as detailed observation on the fracture site, removal of surface deposits (for example, rusts) without altering the fracture size or shape, The book gives examples of analysis of failure involving a crane head sheave hanger, wire rope, transmission shaft, environmental failure of fastening screws, and failures in rail joints. This book is intended for civil and industrial engineers, for technical designers or engineers involved in the maintenance of equipment, machineries, and structures.
