A literature review has been carried out to identify the interactive role of the variables governing the fretting fatigue process and to examine the wide spectrum of the present testing practice. It has been shown that the present practice does not ensure an acceptable degree of uniformity and results repeatability. The issues and areas that should be addressed for future development of standardized test methods and equipment are also identified. A special emphasis is placed on the conceptual development needed for modeling the thermal mechanical aspects, of the contact problem under fretting.

The temperature field in the contact zone has a significant effect on the material microstructure, its properties, the oxidation process, and the thermal contact stresses. To standardize fretting fatigue tests, one has to be able to predict and control the contact temperature. Since direct temperature measurement is practically impossible, analytical models are required to estimate the friction-induced temperatures rise under fretting conditions. The main objective of the present work is to model the thermal constriction phenomenon in fretting fatigue and wear processes, considering the roughness and waviness of contacting surfaces. These asperity-scale models can be combined with large scale analyses, e.g. finite element method, to account for the thermal characteristics of the whole tribo-system, its boundary conditions, as well as the spatial variation in the slip amplitude and coefficient of friction over the interface. The debatable question on whether the contact temperature in fretting fatigue is significant is addressed, considering a wide range of materials and applied loads. The analysis showed that the randomness of the contact size may substantially increase the micro-constriction impedance of the fretting interface. The paper is concluded with recommendations for future work to experimentally validate these models, and to examine the effect of the spatial maldistribution of the micro-contacts, and the effect of surface oxide on the contact temperature prediction.

Classic, comprehensive, and up-to-date Metal Fatigue in Engineering Second Edition For twenty years, Metal Fatigue in Engineering has served as an important textbook and reference for students and practicing engineers concerned with the design, development, and failure analysis of components, structures, and vehicles subjected to repeated loading. Now this generously revised and expanded edition retains the best features of the original while bringing it up to date with the latest developments in the field. As with the First Edition, this book focuses on applied engineering design, with a view to producing products that are safe, reliable, and economical. It offers in-depth coverage of today's most common analytical methods of fatigue design and fatigue life predictions/estimations for metals. Contents are arranged logically, moving from simple to more complex fatigue loading and conditions. Throughout the book, there is a full range of helpful learning aids, including worked examples and hundreds of problems, references, and figures as well as chapter summaries and "design do's and don'ts" sections to help speed and reinforce understanding of the material. The Second Edition contains a vast amount of new information, including: * Enhanced coverage of micro/macro fatigue mechanisms, notch strain analysis, fatigue crack growth at notches, residual stresses, digital prototyping, and fatigue design of weldments * Nonproportional loading and critical plane approaches for multiaxial fatigue * A new chapter on statistical aspects of fatigue
