DYMAT AssociationPresident

DYMAT, the European Association for research into the dynamic behaviour of materials and its applications, celebrates in 2018 its 35th anniversary. This represents an important milestone for our association that groups leading research institutions in Europe and worldwide. Since 1983 DYMAT has organized every three years a five days single session conference of oral presentations and poster exhibitions. This represents the platform to present the most recent scientific achievements on dynamic behaviour of materials.

The 12th DYMAT International Conference, being held between September 9th and 14th 2018, is organized by the French Commissariat à l'Energie Atomique et aux Energies Alternatives (CEA), in Arcachon, France. Specific emphasis was placed on the following key topics: Experimental Techniques, Microstructural Effects, Modelling and Numerical Simulation, and Industrial

Applications. As in the previous two conferences held in Freiburg and Lugano, 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 proceedings papers while, other authors chose to submit their manuscripts to a peer review process for publication in an issue of the “European Physical Journal Special Topics” (EPJ-ST).

As written in the statutes, the principal aim of the Association is to bring together engineers and scientists who are working in the general field of impact with a particular focus on the study of the mechanical properties of materials at high rates of strain, their modelling and associated numerical simulations as well as the applications of this work. For this purpose, DYMAT organizes International Conferences, Technical Meetings, Working Groups and Student Camps. Since 2015, two Technical Meetings have been organized: the 22nd TM on experimental techniques and modelling of brittle materials at high strain-rates held in October 2016, Grenoble, France, and the 23rd TM on dynamic fracture of ductile materials, held in September 2017, Trondheim, Norway. Our gratitude goes respectively to Prof. Pascal Forquin and Prof. Magnus Langseth for the excellent organization of these two events.

DYMAT2018 will have the honour of being the fourth DYMAT International Conference to give the John S. Rinehart Award. This distinction, established in 1990 to recognize outstanding effort and creative work in the science and technology of dynamic processes in materials, was formally awarded every five years on the occasion of EXPLOMET International Conferences. In 2009, DYMAT became 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 two winners. Our sincere congratulations go to George T. (Rusty) Gray III and to Gordon R. Johnson, the two recipients of the John S. Rinehart Award 2018. My sincere gratitude goes to Dr. Antonio Cosculluela and Dr. Eric Buzaud, chairmen of the Conference and co-editors of the 2018 EPJ-ST issue. Antonio and Eric have completed a remarkable work in the organization and the success of this conference. My thanks go to them and their colleagues, who greatly contributed to the success of DYMAT2018.

Finally, I would also like to thank the members of the International Advisory Committee and the Governing Board for their commitment in ensuring the high scientific level of the conference.

Preface

Dear delegates to the DYMAT2018 conference,

The 12th International DYMAT Conference, being held from 9 to 14 September 2018, is organized by the Commissariat à l'Energie Atomique et aux Energies Alternatives (CEA) in partnership with the Institute of Mechanics and Engineering (I2M) of the University of Bordeaux. More than for its natural charm, the foremost reason for choosing Arcachon, is its proximity to Bordeaux, one of the most dynamic towns in Europe. We take the opportunity to thank the Nouvelle Aquitaine region for its generous sponsorship. This conference is a unique occasion to bring together from around the world members of the scientific community who are working on the dynamic behaviour of materials and structures. It is a great honour and a real pleasure for us to have been able to organize this conference. With authors from 32 countries, the DYMAT international conference has once again demonstrated its influence and international character.

As in previous years, the conference has offered two types of publications. The proceedings of the conference have been collected into an issue of the “European Physical Journal - Web of Conferences” (EPJ-WoC). Alternatively, authors were encouraged to submit their articles to a peer review process in order to publish their work in an issue of the “European Physical Journal - Special Topics” (EPJ-ST), entitled “ Advances in the Characterization, Modelling and Simulation of Materials Subjected to High Strain Rates”. Out of more than 250 abstracts submitted, 175 manuscripts were selected for the

proceedings and in addition, 15 papers have been published in the EPJ-ST journal, volume 227, issue 1-2.

Since the last DYMAT international conference, several developments and innovations have been adopted. First, considering the importance of deepening our connections to the next generation of researchers and engineers, an exceptional financial effort has been made to offer a reduced fee to PhD students. We hope to have the pleasure of welcoming a large number of them from all over the world. For this reason, and for the first time, we will hold a pre-conference 3-hour short course: an introduction to DYMAT's fundamental fields of interest that will be taught by three eminent researchers and professors on Sunday, the 9th of September. This course will be open to all DYMAT members, both students and non-students. Moreover, we are proud to announce the revitalization of the prize for the best PhD thesis written in DYMAT's domains of interest since September 2015. The prize will be awarded during the conference.This year, scientific contributions have been distributed among 4 key topics : Experimental Techniques, Microstructural Effects, Modelling and Numerical Simulation, and Industrial Applications. One novelty is that two dedicated poster sessions of 2 hours each have been added to the agenda, so as to provide much better conditions to present work that could not be incorporated into the tight oral presentation schedule. We hope that this new format will foster even more scientific and technical exchanges, in a convivial and relaxed atmosphere.

We wish to express our sincere gratitude to all authors, who once again have massively answered our call for papers. In addition, we would like to express our thanks to the International Advisory Committee and the members of the Governing Board of the DYMAT Association. Their remarkable and continuous support in the reviewing and organization processes has been extremely helpful in setting up the scientific program of the conference. Finally, we would like to address our warmest thanks to the local organizing team for its patience, quick reactions and professional handling of the unexpected. Its invaluable support has made the organization of DYMAT2018 a real pleasure and a great adventure.Together with all our colleagues on the DYMAT Governing Board, we look forward with confidence to DYMAT2018 in the hope that it will break new ground in our chosen field of interest and be of the greatest benefit to all participants.

Welcome to Arcachon and enjoy the conference!

About DYMAT

The DYMAT conferences are of high interest for everybody concerned with the dynamic behaviour of materials with aspects such as experimental techniques, constitutive modelling, micro-structural effects, and numerical simulations.

The dynamic behaviour of materials is relevant in multiple applications such as crashworthiness in transport including cars, trains, boats and airplanes; terminal ballistics related to defence, shielding of satellites, of turbine blades and discs; blast effects due to industrial explosions, terrorist attacks; material processing such as high-speed shaping of metals.

The principal aim of the DYMAT Association is to bring together engineers and scientists from all nations working in these fields. For this purpose, every three years the DYMAT Association organizes an international conference (since 1985). We also encourage the holding of technical meetings, seminars, training courses, student camps.

Devoted to deterrence

The CEA's Military Applications Division (DAM) is responsible for the design, manufacture, through-life support and dismantling of the nuclear warheads that equip France's sea- and airborne deterrence forces. The reliability and safety of French nuclear warheads are now guaranteed without conducting any further nuclear tests, through the Simulation programme, launched in 1996. The DAM is responsible for the design and manufacture of the nuclear reactors and reactor cores on French Navy submarines and aircraft carrier. It assists the Navy with in-service follow-up and through-life support for these reactors. CEA DAM is also in charge of procuring strategic nuclear materials required for the nation's deterrence.

Based on its nuclear fuel and weapons cycles knowledge, CEA DAM also contributes to national and global security through the technical support it provides to the authorities relative to the prevention of nuclear proliferation and terrorism.CEA DAM also provides project management assistance to the French defence procurement agency (DGA) for conventional defence activities, making use of its expertise on the effects of weapons and weapon system vulnerability, CEA DAM has put its expertise in conventional weaponry at the service of the Ministry of the Armed Forces. CEA DAM organizational structure is optimized for the management of its programs: nuclear weapons, nuclear propulsion, nuclear materials, non-proliferation and conventional defence.

Actively involved in French industrial policy

CEA DAM works closely with French industry by applying an industrial policy which relies on the three following principles. CEA DAM remains the prime contractor of its core business: design and guaranteeing of the nuclear package, design and guaranteeing of nuclear warheads, nuclear materials and components, explosives and nuclear warheads re-entry vehicles, design and experiments in the large experimental facilities of the Simulation Program.

CEA�s Military Applications Division (DAM) www-dam.cea.fr

Firstly, CEA DAM carries out the research and the design of its products in its own laboratories. Secondly, CEA DAM transfers design and associated processes to industry. Thirdly, CEA DAM remains the prime contractor of the main systems for which it is responsible. So, more than two-thirds of CEA DAM's budget is devoted to industrial contracts.CEA DAM is also keen to see its centres play an active role in the local economy through their involvement in competitiveness clusters. It finds applications outside its specialist area for its research work through technology transfer to industry and by filing numerous patent applications.

Research Sharing knowledge nationally and internationally (when possible), undergoing scientific assessments by external agencies, and participating in expertise networks are guarantees of scientific credibility. CEA DAM research teams publish some 2,000 scientific publications and reports every year. In addition, CEA DAM experimental resources are made available to the scientific community, and research teams participate in external research programs.

Organization

CEA DAM has five centres with co-ordinated missions, involved in fundamental research, development, and production:

DAM Ile-de-France (DIF), in Bruyères-le-Châtel, near Paris, is dedicated to research on weapons physics, numerical simulation, and the prevention of nuclear proliferation. DIF is also the CEA DAM's engineering centre. The Nuclear Propulsion Unit at the CEA's Cadarache site in the Provence Alpes-Côte d'Azur region, which houses the test facilities and certain nuclear propulsion products, is attached to the DIF.

Cesta, in the Aquitaine region, is dedicated to nuclear weapons architecture and guarantee and to environmental resistance testing. It houses the Megajoule Laser, a key component of CEA's Simulation Program.

Valduc, in the Bourgogne region, is dedicated to nuclear materials and is home to the EPURE experimental facility developed as part of the Simulation Program.

Le Ripault, in the Centre region, is dedicated to non-nuclear materials (chemical explosives, etc.).

About Arcachon

Welcome to Arcachon

Arcachon, situated in a bay – ‘Bassin d�Arcachon� – is one of the gems of the French Atlantic coast. Its mix of beaches, wonderful sea views, extensive ‘Belle Epoque� architecture, great atmosphere and excellent food and wine come together to create a wonderful holiday destination.

History

Arcachon itself is a relatively new town. It was carved out of the pine and oak forest in the early to mid-19th century, first as a place for the sick folk of Bordeaux to go to take in the sea-air and bathe in the water as part of their convalescence, then as an alternative destination to Switzerland for those with tuberculosis. When the railway was extended, cutting the journey time from Bordeaux from 18 hours to two hours, the town swiftly became popular as a seaside resort for the wealthy of Bordeaux as well as Paris. Arcachon officially became a town in 1857, its deeds signed by Napoleon III who in visiting twice, added to the reputation and allure of the town.

Geography

Arcachon lies on the southern bank of Arcachon Bay, a large triangle-shaped bay of the Atlantic Ocean, linked to the sea on its south-west corner by a narrow channel which has a reputation of being quite challenging to navigate. The Bay is home to a rich and diverse wildlife, especially birds and waterfowl, which can be observed all year round. Many parts of the Bay are protected by natural preservation reserves and restricted-access areas. At its southern entrance from the Atlantic Ocean, Arcachon Bay is crowned by Europe's largest sand dune, the Dune du Pilat (also spelled Pyla), nearly 3 kilometres long, 500 metres wide, reaching 107 metres in height.

17

What to see and do

Eating

Arcachon is great for gastronomy – not just oysters but fish and other seafood from the bay, plus the best of the south-west and Basque influences, delicious meals are easy to come by. Enjoying a seafood feast as you watch the sun go down is a simple but memorable pleasure.

Visit the Winter town

Original architecture is the order of the day here. Neo-gothic villas sit alongside Swiss chalets, English cottages and colonial-inspired residences. Depending on style, they are called “innovations”, “follies” or “modest”. Despite this stylistic excess, the 215 villas scattered among the pine trees form a harmonious architectural heritage, unique in France, giving pride of place to gingerbread, bow-windows, multi-coloured façades…

Visit the port

The second largest marina on the Atlantic coast with mooring for 2600 boats, there is also now a heritage quay for the Bassin's traditional boats including the long, narrow, flat-bottomed ‘pinasses', barges and tall ships. If you're up early, get there for 6.45 am to see the fishing catch being landed.

Go on a boat trip

A boat trip gives you a different perspective on Arcachon. There are a number of ferries which traverse the bay including the ‘Transbassin' boat which runs all year, departing from Thiers pier at Arcachon for Bélisaire pier at Cap Ferret. The journey takes 30 minutes. Bicycles are allowed on board.

Lazing about on a beach

As it's situated in a bay, many of Arcachon's beaches are gentle waves and so just the thing for families, but travel just a short distance and you reach the wildness of the Atlantic coast and its surf beaches.

The John S. Rinehart Award

The John S. Rinehart Award was established to recognise outstanding and creative work in the science and technology of dynamic processes in materials. This encompasses the processes by which materials are welded, formed, compacted, and synthesized, as well as dynamic deformation, fracture, and the extremes shock loading effects. The award is named after a true pioneer who witnessed and actively contributed to the field for over forty years.

John S. Rinehart has actively taken part in the development of field of dynamic deformation. He has dedicated his life to the study of stress waves in solids; the results of these investigations have been published in over 130 technical articles and three books, two of them co-authored by John Pearson. Behaviour of metals under impulsive loads, explosive working of metals and stress transients in solids, have been the vade mecum of all scientists and engineers throughout the world working in the field. The simple, no nonsense, yet fundamentally correct approach used by Dr. Rinehart combines the rigorousness of the physicist with the practicality of the engineer. His fifty year career has been divided between government and university, and he has frequently served as a consultant to industry. He has occupied many positions of high responsibility throughout his career:

19

• Director of research and Development for the U.S. coast and Geodetic Survey,

• Director of the Mining Research Laboratory of the Colorado School of Mines, which he founded,

• Assistant Director of the Smithsonian Astrophysical Observatory, • Head of the Mechanics Branch at the Naval Ordnance Test Station,

China Lake, • Professor of Mechanical Engineering at the university of Colorado.

Dr. Rinehart was associated with Dr. E. J. Workman's Ordnance Research Group before this activity became a division of the New Mexico Institute of Mining and Technology in the Early 1950s.

The John Rinehart Award has been given every five years, at the occasion of the EXPLOMET conferences. Since 2009, DYMAT is the custodian of the award.

Origins of the Hopkinson bar and Taylor impact tests

Stephen Walley, Doctor, Research Associate (Retired), Fracture and Shock Physics

Group, Department of Physics, University of Cambridge, United Kingdom

Course description

Systematic, quantitative, static mechanical testing of materials started in the middle of the 19th century, largely due to the increasing use of iron and steel in critical structures such as bridges. The frequent explosions of steam boilers and the realisation that there was no understanding of the effect on steel rails and bridges due to the passage over them of trains also led to the desire to develop high rate tests. However, due to the lack of instrumentation with sufficient time resolution, it was a long time before such tests were developed.

A Short introduction to the Mechanical and Physical Behaviour of Materials under Dynamic Loading

35

Just before the First World War, Bertram Hopkinson developed a technique that for the first time allowed the analysis of mechanical impulse into force and time. This allowed him to explain qualitatively why steel plates spalled when subjected to explosion or impact. His bar method also led to improvements in fuse trains in explosive shells. But it was not until the Second World War that his invention was used by G.I. Taylor, Enrico Volterra and R.M. Davies to measure the dynamic strengths of soft materials such as explosives and plastics. After the war had ended, Kolsky developed a detonator-loaded version that could be used to measure the dynamic stress-strain curves of metals.During World War 2, G.I. Taylor also analysed the rod-on-anvil technique (developed in France at the beginning of the 20th century) to enable the dynamic compressive strengths of the hard steels used in tank armour to be estimated.The use of the split Hopkinson (or Kolsky) pressure bar to obtain the dynamic properties of materials began to ‘take off' in the 1970s with a few tens of papers a year (now there are around 400 per annum). The technique is used for a wide range of materials, both brittle and ductile.The Taylor impact test is no longer used for its original purpose (Kolsky bars give much more accurate data). But it has experienced a new lease of life in recent years as a severe test of the predictive abilities of constitutive models and numerical methods. Instructor

Stephen M. Walley read Natural Sciences at Corpus Christi College, University of Cambridge 1974-1977, specialising in Physics in his final year. He graduated BA(Hons) in 1977. He then attended Bristol University for one year to do an MSc in the Physics of Materials. He started PhD research in 1978 at the Cavendish Laboratory on impact erosion damage to polyethylene. He graduated PhD from the University of Cambridge in the summer of 1983. Since then he has been involved in a number of projects at the Cavendish Laboratory including ballistic impact on glass/polymer laminates, ignition mechanisms of propellants and polymer-bonded explosives, and high strain rate mechanical properties of polymers, metals and energetic materials. He is minutes secretary of the Governing Board of the DYMAT Association. He is author or co-author of about 100 published journal and conference papers. In retirement, he is writing papers and book chapters of a more historical nature as well as writing up for publication studies performed in recent years by former members of the Fracture and Shock Physics Group.

Dynamic Testing of Ductile Materials

Patricia Verleysen, Professor, MST-DyMaLab Research Group, EEMMECS Department,

Ghent University, Belgium

Course description

This lecture starts with an outline of the basic principles of dynamic testing of ductile materials. To characterise the dynamic behaviour of ductile materials, split Hopkinson bar (SHB) test setups are commonly used. The Hopkinson test technique allows reaching strain rates ranging from 102 s-1 up to 104 s-1. This short course addresses the merits and limits of SHB setups to test ductile materials. Key topics include:

• Sample geometry: a judicious selection of the specimen dimensions and geometry is of paramount importance for the quality of the obtained results. Recommendations on sample geometry will be given.

• Shear testing: since the widely used tension and compression tests exhibit some inherent shortcomings, which are even more pronounced at higher strain rates, specific attention will be devoted to dynamic shear testing of metals.

Short Course

37

• Identification of damage and fracture properties: in addition to measuring dynamic plasticity properties, Hopkinson tests allow identifying damage and fracture parameters of ductile materials as well. During this course, test techniques to evaluate the effect of the stress state (e.g. triaxiality, Lode angle) on ductile damage and fracture will be introduced.

• Application full field deformation measurement techniques: by their very nature, Hopkinson tests have a very short duration (~ms) and use fairly small specimens (~mm). The use of high speed cameras and full field deformation measurement techniques such as digital image correlation can provide a vault of very valuable information to complement the traditional measurements.

Instructor

Prof. Patricia Verleysen is head of DyMaLab, the Ghent University (Belgium) laboratory for Dynamic Materials Research. DyMaLab focuses on research into the mechanical behaviour of materials under high strain rate dynamic loading conditions and the microstructural phenomena lying at the origin of the observed behaviour. Research at DyMaLab has a strong experimental component. Test techniques are developed to identify the strain rate dependent constitutive response, including damage and fracture. To this purpose DyMaLab disposes of a wide variety of experimental test facilities, all equipped with state-of-the-art measurement devices. Based on the experimental observations, models are developed to describe the strain rate and temperature dependent mechanical material response.In addition to high speed material test devices, facilities have been designed and built which allow simulating high speed forming processes and dynamic severe plastic deformation at labscale.

Experimental approaches to characterize the

dynamic behaviour of brittle materials

Pascal Forquin, full-professor, Laboratory of Soils, Solids, Structures and Risks,

Grenoble Alpes University, France

Course description

Brittle materials such as ceramics, rocks, glass and concrete, are widely used in many civil and military applications involving dynamic loading, impulse loading, shock or impact: “Explosive compaction of powders”, “blasting of rocks”, “seismological studies”, “ballistic impact against ceramic armour or transparent windshield”, “plastic explosive against concrete structures”... In most of these applications, the brittle material is subjected to intense loading characterized by high or very high strain-rates (hundreds to several tens of thousands 1/s), high pressure (hundreds to thousands of MPa) leading to extreme and specific damage modes such as multiple fragmentation, dynamic cracking, pore collapse, shearing and mode II fracturing or microplasticity mechanisms etc.

Additionally, brittle materials present complex and fascinating features that justify greater efforts to develop research works. Indeed, they are

39

characterized by random failure stresses under static tension or unconfined compression loadings. At low strain-rates they are sensitive to size effects, the larger the sample the lower its mean strength. In addition, the tensile strength of brittle materials, which increases with the strain-rate and the behaviour of brittle materials at high strain-rates, becomes deterministic. Furthermore, brittle materials are strongly sensitive to confining pressure, their behaviour being more and more ductile with the increase of pressure level. This course aims at describing the principle and data processing of popular experimental techniques (Hopkinson pressure bar testing, planar impacts) used to investigate the behaviour of brittle materials at high-loading rates as well as their limitations and drawbacks. A particular attention is devoted to the relationship between microstructural parameters and the dynamic response of brittle materials. Instructor

Pascal Forquin is head of the Risk and Vulnerability Division in the Laboratory of Soils, Solids, Structures and Risks at the Grenoble Alpes University, Grenoble, France. He has extensive experience with dynamic testing of brittle materials (ceramics, rocks, concrete), notably the edge-on impact, the spalling and quasi-oedometric compression techniques on Hopkinson bars as well as with the modelling of fragmentation processes in brittle solids under impact loading. Prof. Forquin is elected member of the DYMAT Governing Board (European association) and is Associate Technical Editor of JDBM (Journal of Dynamic Behaviour of Materials). He organized the 2016-LWAG workshop (Light-Weight Armour for Defence & Security) and the 22nd DYMAT Technical Meeting dedicated to “Experimental testing and modelling of brittle materials at high strain-rates”, both held in Grenoble in October 2016.

Thiot Ingenierie, created in 1988 by Patrick Thiot, has developed unique expertise in the development, design and manufacture of laboratory launchers. For the last thirty years, these high-tech devices have been used in the world's most prestigious research centers and laboratories. Our scientific and technological expertise in high-pressure equipment and shock physics has enabled us to expand the scope of our activity. Our product range now includes: single-stage gas guns, two-stage light-gas guns, firing-range chambers, detonation chambers, explosion-containment chambers, Split-Hopkinson bars for compression or direct-tensile tests.In 2008, Thiot Ingenierie decided to offer its services directly to its clients by opening its own shock physics laboratory with also numerical simulation and R&D center.

The company now boasts numerous test facilities - equipped with the most advanced metrology tools available - to carry out tests, primarily for the requirements of the defence, aerospace, aeronautics and research sectors. These tests serve to observe, study and analyse the behavior of materials subjected to different levels of velocity impacts: from a few m/s for crash phenomena up to 10 km/s for space debris collision. The tests conducted in our laboratory allow us to observe impact phenomena by the nanosecond and measure movements in the order of a micrometer. This is all made possible due to our state-of-the-art instrumentation, which allows us to study materials down to their very core during the short duration of an impact.

At Thiot Ingenierie, we know that it is essential to combine laboratory testing with numerical simulation, both to gain a good understanding of how materials behave when subjected to shocks and to obtain reliable and realistic numerical simulation results. How does ceramic armor behave when hit by a bullet? What should the security perimeter be for demilitarization operations? How well can an armored door stand up to an explosion? Numerical simulation of fast phenomena - impact, blast, and crash phenomena - makes it possible to appropriately determine material behavior laws without the need for long test campaigns, assess the vulnerability of materials and structures, and extrapolate the results of laboratory tests to full-scale phenomena. We put our expertise in shock physics and numerical simulation at the service of a great number of manufacturers, scientific organizations and collaborative research programs.Our strength lies in the ability of our experts to combine dynamic laboratory tests and numerical simulation to provide you with global, exhaustive and practical expertise. We provide a comprehensive service to cover your shock-physics requirements. Today, more than 30 collaborators combine physical laboratory tests with expertise in numerical simulation to help you gain a better understanding of your materials and optimize your products.

The electro-optical Extensometer 200XR contactlessly measures the motion of two black-and-white edges (targets) on a sample. The analog output signal is proportional to the strain. The frequency range of Model 200XR amounts to 0 – 250 kHz. The integrated viewer and the two liquid crystal displays simplify the performance of the adjustments required for the setup of the instrument; the viewer also allows observing the black-and-white edges on the sample while measuring takes place. Lens units with different measuring ranges of 1 mm - 500 mm can be mounted to Model 200XR by means of a flange. The calibration of the lens units results in an output voltage Δl of ±10V for the range of strain.

There is the option of delivering the 200XR with a switch to toggle between the two measuring axes; this allows using the instrument also as Biaxial Extensometer 200XR in order to measure strain in either vertical or horizontal direction.

The standard gauge length lo is 75 mm. A continuously adjustable gauge length of 1 mm upto 125 mm can be established by gauge length adapters mounted to the lens units.

Nouvelle Aquitaine is the name of the new region created by the territorial reform that took effect on January 1, 2016. It combines the former administrative regions of Aquitaine, Poitou-Charentes and Limousin.Its administrative centre or ‘préfecture' and capital is Bordeaux. It is also France's 7th largest French city with 850,000 inhabitants. The region has 25 major urban areas, among which the most important after Bordeaux are Bayonne (288,000 inhabitants), Limoges (283,000), Poitiers (255,000), Pau (241,000), and La Rochelle (206,000), as well as 11 major clusters. The growth of its population, particularly marked on the coast, makes this one of the most attractive areas economically in France: the new region outperforms the Paris-Île de France and Provence-Alpes-Côte d'Azur in terms of demographic dynamism.

EconomyAgriculture and of course viticulture, tourism, aerospace and industrial ceramics are the base of the region's economy. However, Nouvelle-Aquitaine has perfectly integrated innovation in its economic strategy, notably through support for the emergence of key technologies: nanostructural materials, thermostructural composites, non-destructive control, organic electronics, catalysis, structural bonding, surface treatments or high-performance structural composites. The region coordinates the organization of a value chain that groups together enterprises, training networks and technological centres.With this in mind, the Nouvelle Aquitaine region has established partnerships with major industrial French companies such as ARKEMA, ARIANE Group, AIRBUS, THALES, TORAY, SAFRAN and EPSILON COMPOSITE. Overall, the sector of chemistry and materials represents 30 000 jobs.Nouvelle Aquitaine is also the largest European agricultural region in terms of turnover, and the first region in France in terms of employment in the tourism sector.Indeed, the prestigious seaside resorts of Arcachon, Biarritz and Royan, but also the Pyrénées ski resorts sustain this thriving sector.Nouvelle Aquitaine is also the second area of France (after Paris-Ile de France) with the largest number of Universities and “Grandes Ecoles” (Bordeaux, La Rochelle, Limoges, Poitiers and Pau).

The region is obviously well connected:The A10 motorway connects Bordeaux to Paris and to Spain, the A89 to Clermont-Ferrand then the Rhône Valley, and the A62-A61 to Toulouse and the Mediterranean coast. Also, the TGV railway connects it to Paris, Toulouse and Spain.Finally, Nouvelle Aquitaine has 5 international airports: Bordeaux-Mérignac, Bergerac, Limoges-Bellegarde, Biarritz-Anglet-Bayonne and Pau-Pyrénées.Area: 84,061 km²Population: 5,911,482 (27/12/2017)
