He also acted as Secretary of ESIS TC20 from 2000 to 2005: the activity of ESIS TCO led Stefano to cooperate to ASTM E04 Committee for writing the standard E2283-03, in which the European experiences were condensed. He is Chairman of TC24 since 2010, where he organized and hosted many international meetings (http://esistc24.mecc.polimi.it). He is Chairman and organizer of the 3rd Int. Symposium Fatigue Design and Material, held in Lecco, September 2017. His main research achievements are: leadership in the fatigue and damage tolerance assessment of railway axles together with planning of maintenance and inspections; development of probabilistic metods for defect analysis and assessment under LCF and HCF; development of a test method for measuring growth rate for short cracks under RCF condition. Recently, S. Beretta been devoting also to other two fields of research: i) the application of DIC to the analysis of fatigue damage in TiAl alloys and the accurate measurements of crack closure in different conditions (HCF and LCF); ii) the fatigue of AM materials. The latter will be the topic of his lecture.

After a PhD also in Grenoble (1993) and a Post Doc at Imperial College in London he was appointed Associate Professor at Institut National des Sciences Appliquées de Lyon (INSA LYON) in 1994. Since 2003 he is a Professor of Materials Science at INSA (Mechanical Engineering Department). The main focus of his research is on the characterization of damage in advanced metallic materials submitted to mechanical loading. Through collaborations with several synchrotron sources, among which the European Synchrotron Facility (ESRF) in Grenoble, he has pioneered the use of high resolution synchrotron X ray tomography for the non destructive 3D characterization of materials.
He was a co-Chair of the International Conference on Three dimensional Materials Science (3DMS-14 – Annecy), and of the former edition of Fatigue Design & Materials Defects (FDMD-II – Paris). He has supervised or co-supervised more than 30 PhD projects and post doctoral research programs in the field of fatigue of metals and three dimensional characterization; he is the co-author of more than a hundred papers on that topic and the co-author of a book on 3D Imaging in Mechanics of Materials (Hermes ed.).

James T. Burns has been an Assistant Professor in the Center for Electrochemical Science and Engineering within the Department of Materials Science and Engineering at the University of Virginia since 2011. Professor Burns received a B.S degree from the United States Air Force Academy in Engineering Mechanics (Materials track) with a Mathematics minor in 2002. He completed his M.S. and Ph.D. in Material Science and Engineering at the University of Virginia in 2006 and 2010, respectively. After his commission he served as an Aircraft Battle Damage Engineer and Assistant Aircraft Structural Integrity Program (ASIP) manager for the C-130 from 2002-2004 and he served as a Research Engineer at the Air Force Research Laboratory – Materials and Manufacturing Directorate from 2006-2010. His research focuses on the intersection of metallurgy, solid mechanics and chemistry which is currently at the forefront of several important engineering challenges. Alloy development and modeling of the fatigue/fracture behavior of complex metal components necessitates an understanding of the pertinent microstructure and damage physics. Specifically, the interaction of localized stress/strain with environment conditions, with a particular emphasis on behavior at the crack tip. In general, experimental data from controlled environmental testing are coupled with high fidelity characterization techniques to gain mechanistic understanding of the damage process; such knowledge is used to inform theoretical and engineering level models.


Hans-Jürgen Christ (Germany)

Hans-Jürgen Christ was graduated from the University of Erlangen-Nürnberg in 1980 and received a PhD from the same university in 1984 and a habilitation in 1990. After a stay as visiting scientist at the University of Illinois at Urbana-Champaign, he is since 1993 Full Professor of Materials Engineering at the University of Siegen. The main objective of research is a detailed understanding of the behaviour of metals and alloys under complex conditions representing those in technical service of engineering materials. For this purpose engineering materials are subjected to near-service conditions and both the macroscopic and the microstructural changes are analyzed. The correlation of microscopic processes with the resulting macroscopic changes in properties are used to obtain information on the relevant mechanisms and damage processes, in order to develop a better prediction of the application limits and the expected lifetime of materials under service conditions. The computer-aided description of the material behaviour based on the occurring physical processes serve for the transfer of the experimentally gained results to new applications.
He is the author or coauthor of 540 articles, 1 monograph, 2 textbooks, Editor of 5 special issues of international peer-reviewed journals, and the Editor of 4 proceedings of conferences.
