Summer School on Models of Generalized Continua characterized by Quasi-Inextensible Fibrous Structures : New Ideas for Models and Applications 2016

19-23 September 2016, Arpino, Italy

Continua with extensible fibers can be regarded as Generalized Continua. They have a variety of applications, ranging from weaving techniques used in cutting-edge fields such as aeronautics, biological soft tissues and some biomaterials. Compared with the historical research specific to granular media, the field of fibers suffers from a delay in understanding and modeling of complex phenomena that are their own, late that deserves to be filled, given the scope of their applications in high added value technologies. The scientific problems that raise regarding the development of homogenization methods to allow to substitute them an equivalent homogeneous medium, the presence of strong geometric nonlinearity related to changes in geometry, internal scale effects leading to media type models continuous generalized, the design of experimental procedures for identifying specific mechanical properties and in particular non-conventional modules, the design of metamaterials fibrous
architecture for acoustic applications, the development of clean numerical methods to handle large structures incorporating a multiscale aspects. The acronym MCGFI is used hereafter to describe the theme of ET (Ecole Thématique), which will be dedicated to the Generalized Continuum that consists of extensible fibers. The school primarily aims to allow scientists belong to research units (permanent but also temporary, in particular PhD students and postdocs) to acquire the knowledge and
methodologies for analyzing the behavior of MCGFI at different scales. The complexity of these environments requires to provide a forum for training and exchanges to disseminate methods of analysis of these environments within a larger community. Participants (selected from the the CNRS GdR No. 3542 3MF alias Multiscale Mechanics of Fibrous Media) will be able to meet and to interact on a topical
theme, through thematic courses of deepening of research themes and the scenario in the workshops to confront different points of view.

The venue in Italy is due to the recent creation (2014) of LIA Coss&Vita , supported by the Federation
Francilienne de Mecanique and M&MoCS (International Research Center for the Mathematics and Mechanics of Complex Systems). The aim of the LIA is to enhance the expertise of the communities in the field of generalized and applications continuum.

Teaching Methods : The educational program of the School includes lectures, transversal workshops, courses/presentations on advances in research, round tables, discussions also while eating ice creams.

Organization and rhythm of the days : The days will be organized in the following format : 2 hours of lectures in the morning on the themes of ET, followed by a pause of 2 hours and seminars supervised by a senior, in a spirit of interdisciplinary. 3 hours of free time is scheduled for the afternoon of free scientific exchange and relaxation, followed by 2hrs classes / lectures of research. Exchanges and return on seminars organized also in the late afternoon. Lessons provided by the trainers aims to introduce the themes of ET, then to promote exchanges by sharing time between presentation with support and discussion. Informal discussions will enable participants to exchange information about their scientific interests and enrich their own vision of the concepts assimilated during this ET. Plenary sessions will also be organized to discuss on the seminars and make a report, to compare points of view. Groups of students will be formed in order to ensure a sharing of disciplinary skills within each group. Each group will have the mission to address a specific issue of research under the guidance of trainers who coordinate the group’s activities.

Provisional timetable : There will be the welcome to all participants on Sunday 18 in the evening. The detailed program will be decided in the first round table at the beginning of the school.

Speakers :
Philippe Boisse (LAMCOS, Lyon),
Claude Boutin (LTDS–ENTPE Lyon),
Manuel Collet (CNRS at LTDS, Ecole Centrale Lyon)
Francesco dell’Isola (SAPIENZA University of Rome, M&MoCS Centre, University of L’Aquila),
Justin Dirrenberger (PIMM Lab Arts & Métiers-ParisTech)
Damien Durville (MSSMat Ecole Centrale Paris)
Victor Eremeyev (Rzeszow University of Technolodgy),
Jean-François Ganghoffer (LEMTA – Université de Lorraine)
Phillip Harrison (School of Engineering, University of Glasgow)
Laurent Orgeas ((3SR Lab, CNRS/Univ. Grenoble Alpes)

To be Confirmed : Pierre Seppecher (Université de Toulon), David Steigmann (University of California Berkeley, USA.

Main themes : Quasi-inextensible fibrous media, Multiscale methods, Generalized Continuum, Dynamic and acoustic properties, Metamaterials, Technical textile, Living soft tissue, Numerical methods, Mathematical aspects, Media with microstructure

Location : The School will take place in Arpino, a picturesque ancient city south of Roma.

Audience : The public is made up of students and scientists engaged in research on the fibrous media, homogenization methods, the generalized continuum. People who plan to engage on these research areas are also welcome, particularly in the framework of a conversion or a change of theme. The panel of researchers referred is naturally made up of the members of the CNRS GDR 3MF No. 3542.

Prerequisites for participation : Participants will be expected to have master-level skills in mechanics of materials (Continuum, notion of constitutive law, elasticity). Other skills required will be made in the form of introductory course of each day, covering all the themes of ET.

Registraton :

Registration Fee : A fee will be required to participants, following the policy of LIA to keep fees as low as possible. If you are interested in participating, and for any information, please contact the Organizers of the School at the following email addresses :
