Object of the Colloquium


The centenary in 2009 of the publication of the much cited, but very little read, monograph by the Cosserat brothers on the “Theory of deformable bodies” offers a timely opportunity to examine the strong influence of, and the progress and innovation in, the mechanics of so-called generalized continua., Cosserat continua providing one example of such generalized continua. The actuality of such a subject matter is enhanced by the recognized physical fact that in virtually all physical natural or man-made materials and systems, interactions exist between mechanical processes at different spatial scales.

Nowadays, generalized continua facilitate the development of new metallurgical procedures as well as the production of artificial materials with a controlled microstructure. They help predict the failure of heterogeneous brittle materials such as concrete and ice. Several non-destructive testing techniques are based on the averaged material properties predicted by the generalized continua. The rapidly advancing nano-technologies are seeking for appropriate modelling approaches of which the one based on the concept of generalized continua is considered to be very promising.

Generalized continua such as micropolar or oriented materials, micromorphic continua, strain-gradient materials, bodies with weakly or strongly nonlocal interactions are also emerging as an integral part of the multi-scale numerical techniques. These techniques aim at coupling different spatial scales in one numerical scheme. Starting from the quantum-mechanical description, the simulations proceed into the atomistic, molecular, micro and then to the continuum scale. The latter scale is often broken into two sub-scales: the generalized and the classical continuum. The latter is then considered as representative of the averaged properties of the generalized continuum.

The short discussion above shows that generalized continua are of interest both theoretically and practically and deserve to be discussed by theoreticians and experimentalists representing various fields of mechanics and physics. This will be done in the framework of this Colloquium, the aim of which is to discuss advances in the theory, experimental identification, numerical implementation and applications of the generalized continua. Particular topics to be addressed during the Colloquium could be

- Phenomenology of generalized continua,
- Derivation techniques (homogenization, crystal-lattice dynamics, etc),
- Generalized continua versus discrete models,
- The energy, momentum and moment of momentum in generalized continua,
- Causality and waves in generalized continua,
- Experimental identification of parameters of the generalized continua,
- Numerical implementation of the generalized continua,
- Classical and emerging applications of the generalized continua: nanomechanics, biology, life sciences, earth sciences, civil and mechanical engineering, etc,
- Technological advances facilitated by the generalized continuum theories,
- Non-destructive testing techniques based on the generalized continuum properties.

The time devoted to the Colloquium allows only for about 40 oral presentations of 20-30 minutes.

The possibility to publish the full text of the contributions in book form is under consideration.


Local organization: IJLRdA-UPMC-Paris 6: Gérard A.Maugin (Chair), Daniel Lhuillier, Joël Pouget, Martine Rousseau, Cécile Baron, Ingrid Masson, Simona Otarasanu

This Colloquium is under the auspices of the EUROMECH Society, the Association Française de Mécanique, the Engineering UFR of the UPMC, the STII Scientific Department of CNRS, France; It is locally organized by the MPIA (Modelling and Propagation) Team of the Institut Jean le Rond d’Alembert.



NOTE : The Colloquium organizers do not arrange for travel to Paris or hotel stay in Paris. There is no social program for accompanying persons as Paris offers so many opportunities (monuments, museums, shops, etc).

General Schedule: The registration desk will open at 9:00 in the morning of May 13th, and the Colloquium will officially close on Saturday May 16th at 12:00. (if some lecturers are missing, we may well finish in the evening of Friday May 15th). The opening of the Colloquium is at 10:00 on May 13th; The first lecture starts at 10:30.

The venue of the Colloquium is the Jussieu campus (Metro station: Jussieu, Paris, 5th Arrondissement/District) of the Université Pierre et Marie Curie, Bâtiment/Building “Esclangon”, Lecture room/Amphitheatre “Durand” (Coffee breaks and May 13 reception at 7:00pm in the basement of the same building, in the original caves of the “Halle aux Vins” (Wine Cellar) on which place the UPMC was built in the 1960s. Lunches will also probably be served in this Wine cellar. (Interested people can also use the University restaurant –medium/low quality) The social dinner will take place at 8:00pm at Restaurant “Amore Mio”, 13 rue Linné, 75005 Paris at a few minutes walk from the meeting place.
