Fatigue 2018

The Fatigue 2018 Congress will be the twelfth in a series of major international conferences held since 1981. This series aims to provide a discussion forum for both fundamental aspects and practical applications of fatigue, covering all aspects of fatigue, all type of materials, and all fields of interest: transportation, energy, electronics, civil engineering, medicine, …

Foreword

For structural Integrity of Aircraft, Nuclear Power Plants, Space Rockets, Ships, Automobiles, Biomedical Devices, and many other applications, fatigue is commonly the dominant factor of importance over the life cycle of the structure in question. What makes fatigue design difficult is that it is not a traditional science, but rather a large complex domain consisting of a mixture of scientific disciplines (materials science, physics, statistics, solid mechanics, chemistry etc.) and engineering areas (loads, design, stress analysis, production systems, maintenance, computer systems, full scale testing etc.). The required competence for fatigue design, or indeed failure analysis, depends on the complexity and certification procedure for the structure considered.

The International Fatigue Series/Congresses started in Europe with meetings in Sweden 1981, UK 1984, and then went to the USA 1987 after which the series became established as the pre-eminent world conference in the field of fatigue. Meetings have subsequently been held in Hawaii 1990, Canada 1993, Germany 1996, China 1999, Sweden 2002, USA 2006, The Czech Republic 2010, and Australia 2014. This global distribution of meetings is in the tradition of scientific practice, i.e. to share, disseminate, and discuss results, problems, models and new ideas between scientists around the world. Hence, it is a great pleasure to once again be able to meet old friends, but also newcomers in the fatigue field, during the 12th International Fatigue Congress, as the series returns to Europe, with France, and specifically Poitiers being the venue.

The French bid to host Fatigue 2018 was extremely strong, with support not only from the local organizations: University of Poitiers, ISAE-ENSMA, Pprime Institute, and CNRS, but also from SF2M (French Society for Materials and Metallurgy), Airbus Group, Constellium, SAFRAN, Framatome, ONERA; and Renault. The conference chair and his co-chairs are very well known scientists in the fatigue field. At the time of the bid also honorary chairman Jean Petit was involved in the organizing committee. Unfortunately, Jean (a former leader of the Poitiers fatigue group, a renowned world expert in the field, and a great personal friend of mine) has since passed away. I suggest that we pay our respects by dedicating Fatigue 2018 to his memory. Recently, also the chairman, Graham Clark, of the last meeting in Melbourne, Australia, passed away after a long period of illness. That congress yielded a profit, which has generously been transferred to the present organizers in order to organize a suitable price. This will be a best poster paper award, named the Graham C Clark price to honor Graham´s memory.

I wish all participants in Fatigue 2018 a very successful meeting, and I also wish to thank the present congress chairman, Gilbert Hénaff, and his team for all the effort leading up to this exciting week.

Welcome address

FATIGUE 2018 is the 12^th meeting of the International Fatigue Congress.

During the FATIGUE 2014 Congress held in Melbourne, the International Steering Committee of the International fatigue Congress agreed to a proposal to stage the FATIGUE 2018 Congress in Poitiers, France.

This decision crowns a pioneering research work initiated more than 50 years ago in a research group on physical metallurgy and mechanics of materials in ISAE-ENSMA, first in collaboration with the metallurgical industry, and then with aircraft and nuclear industries. Since that time, R & D work on this topic has intensified throughout the country, both in academic laboratories and in research centers and industries, so as to achieve the highest level as illustrated by numerous participations to international conferences, meetings or workshops, and by significant contributions to literature dedicated to the various aspects of Fatigue and Fracture of Materials (articles, books…).In addition, the Fatigue 2018 Congress is co-organized with SF2M (French Society for Materials and Metallurgy), and more particularly the Fatigue Technical Committee which organized a special session on New Trends in Fatigue Design.

There is no doubt that this twelfth edition will be part of the now long tradition of the Congress series as the privileged forum for intensive exchanges between academic and industrial experts from all around the world on the latest advances in cutting-edge experimental techniques, as well as on theoretical and numerical approaches, life prediction, failure analysis and maintenance procedures. A major challenge for the community is however to take into account new demands from an ever moving world, for instance through the development of additive manufacturing processes while ensuring always safer operating conditions of engineering structures.

The Congress Chairs with the Local Organizing Committee of FATIGUE 2018 warmly welcome you as participants in the 12^th International Fatigue Congress, and would like to thank all the presenters, sponsors, exhibitors, session chairs, members of the International Scientific Committee for their outstanding contribution. The support of ONR Global for the publication of the congress proceedings in “Matec Web of Conference” is particularly acknowledged. We sincerely hope that this congress will be extremely enriching for all of you and that you will appreciate the charm of a medium-size French city.
