DYMAT 2012 - 10th International Conference on the Mechanical and Physical Behaviour of Materials under Dynamic Loading
Freiburg, Germany, September 2nd-7th, 2012

The DYMAT International Conference is a “compelling scientific event” for engineers and scientists working in the dynamic behaviour of materials field. Since 1983, DYMAT has been organizing a five days single sessions of oral presentations and poster exhibitions with proceedings available at the beginning of the conferences. Well-known for its scientific interest, the triennially DYMAT International Conferences are the platform to present the most recent scientific achievements on dynamic behaviour of materials relevant to crashworthiness in all types of transports; terminal ballistics related to defence and shielding of satellites, of turbine; blast effects due to industrial explosions, terrorist attacks; material processing such as high speed machining.

The 10th DYMAT International Conference, programmed between September 2nd and 7th 2012, was organized by the Fraunhofer Institute for High Speed Dynamics, Ernst Mach Institute, in Freiburg, Germany. Specific emphasis was set to five key topics: Experimental Techniques, Microstructural Effects, Biomechanics, Modeling and Numerical Simulation, and Industrial Applications. With authors from 26 countries, the DYMAT International Conference proofed once more its international character. For the first time the Conference offered two types of publications. The contributions in this current issue of “European Physical Journal Web of Conferences” (EPJ-WoC) were submitted as proceeding papers. Alternatively, authors could submit manuscripts to a peer review process and publish in an issue of the “European Physical Journal Special Topics” (EPJ-ST), entitled “Characterization, Modeling and Simulation of Materials at High Strain Rates”.

The success of this conference also underlined the interest of the scientific community regarding the DYMAT Association, which celebrated its 29th anniversary in 2012, and which always highly promoted work in the field of the dynamic behaviour of materials. With this aim, the Association has organized several “Technical Meetings” (TM) on special topics in the field of dynamic behaviour of materials. Since 2009, two TM have been organized with the 19th TM on polymers and composites held in December 2010, Strasbourg, France, and with the 20th TM on nanomaterials, metallic glasses and architecturally designed materials, held in September 2011 at the “Assemblée Nationale” in Paris, France. In addition to the Technical Meetings, the Governing Board has initiated in 2010 a bi-annual seminar series for PhD students named “DYMAT Student Camp” (DSC). The first one was held in October 2010, in Guétary, France, and the second one in June 2012, in Tampere, Finland. These seminars have provided a real momentum for exchanges between young researchers. And the last but not least, the Association financially supported the organization of seminars and workshops related to the dynamic behaviour of materials, encouraged a DYMAT sub-group “Light-Weight Armour Group” (LWAG), provided to DYMAT members through the website’s pdf files of all published papers since 1983 in the proceedings of the International Conferences and TM.

DYMAT 2012 will have the honour of being the second DYMAT International Conference to give the John S. Rinehart’s Award. This distinction, established in 1990 to recognize outstanding effort and creative work in the science and technology of dynamic processes in materials, has been awarded every five years on the occasion of several EXPLOMET International Conferences. Since 2009, DYMAT is the Custodian of the Award. A special jury, composed of the members of the DYMAT International Advisory Committee and members of the DYMAT Governing Board, voted and selected one winner. Our sincere congratulations go to Professor Alain Molinari from the University of Metz, who is the recipient of the John S. Rinehart Award 2012.

I cannot conclude this foreword without saying how much we are grateful to Professor Stefan Hiermaier, chairman of the Conference and editor of the EPJ-ST issue, who has completed a remarkable work in the organization and the success of this meeting. My thanks also go to his colleagues, who greatly contributed to this success. Finally, I would also like to thank the members of the International Advisory Committee and the Governing Board for their implication in ensuring the high scientific level of the conference.

Professor Alain Molinari

Winner of the DYMAT 2012 John Rinehart Award

Alain Molinari

Alain Molinari was raised in Lorraine, France, and graduated from the University of Strasbourg (MS) and the University of Metz (PhD). He is professor of solid mechanics at the University of Lorraine where he conducted his entire academic career and was jointly “professeur chargé de cours” at Ecole Polytechnique during 14 years. He spent five years abroad, mostly in the USA, where he was a visiting professor at Brown University, the California Institute of Technology, the University of California at San Diego, the San Diego State University, and the Johns Hopkins University. His research on high strain rate phenomena was initiated during a sabbatical leave at Brown University (Providence, USA) in 1981 where he was introduced to the fascinating problem of adiabatic shearing by Rod Clifton and the late Jacques Duffy. Since his return to France, he has been head of the group “dynamic loading and extreme conditions” of the Laboratory of Physics and Mechanics of Materials at the University of Lorraine at Metz for 30 years.

His research activity comprises the theoretical analysis of dynamic damage by strain localization and microvoiding, and phase transformation under impact loading. He brought forward new constitutive models for the quasistatic and dynamic response of metals. The multiscale approaches that he proposed for the modeling of the viscoplastic response of polycrystalline materials are used worldwide. Motivated by practical applications of his fundamental research in dynamic plasticity, he has developed a new modeling of high speed machining. His research interests include also porous materials, powder metallurgy, spark plasma sintering and nano-cutting. He obtained the “Grand Prix de la Recherche des Universit´es de Lorraine” (1981), was awarded the Clark B. Millikan distinguished visiting professorship at Caltech (California, 1996), was distinguished scholar and Gledden Senior Fellow at the University of Western Australia (1995 and 1997), has received the Spiru Haret Award of the Romania Academy of Sciences (jointly with Prof. C. Faciu in 2008) and was awarded a chair of excellence at the University Carlos III of Madrid (2009 and 2011). He has organized or co-organized several conferences on high speed machining and material instabilities, and is author and co-author of about 200 research papers and co-editor of one book.
