  Information:	The reliable numerical simulation of the development of cracks in concrete plays an important role for the integrity assessment of concrete structures. To this end a large number of material models for concrete cracking based on different theories (e.g., damage mechanics, fracture mechanics, plasticity theory and combinations of the mentioned theories) as well as advanced finite element methods suitable for the representation of cracks have been developed in recent years. The aim of the Colloquium is to review and to assess available models for the numerical simulation of concrete cracking and to discuss new approaches. Special emphasis will be put on the potentials and drawbacks of the different approaches for practical applications in Civil Engineering.

• [463] Size-dependent Mechanics of Materials

Onck University of Groningen Micromechanics of Materials Nijenborgh 4, 9747 AG Groningen The Netherlands Phone: +31-(0)50 363 8039, Fax: +31-(0)50 363 4886 E-mail: p.r.onck@phys.rug.nl Prof. Dr. T. Pardoen Université Catholique de Louvain Materials Science and Processes Department PCIM, Bâtiment Réaumur Place Sainte Barbe 2 1348 Louvain-la-Neuve Belgium EUROMECH contact person: Prof. E. van der Giessen Website
  Information:	The main driving force in modern technology, including MEMS, is to make microsystems of smaller dimensions. This poses enormous technological challenges on manufacturing procedures, both on the structural as well as microstructural level. In design, on the other hand, the engineer is faced with mechanical behavior that is inherently size dependent. Many examples have appeared in the literature showing pronounced size effects in shear, torsion, tension, indentation and fracture/cracking tests. Concepts from mechanics of materials that are based on a classical, size-independent, continuum description are not able to account for this. Thus, there is a need for new mechanics, able to address size-dependent deformation and fracture. The goal of this colloquium is to provide a platform on which the above issues can be addressed. Contributions are solicited that address size-dependent behavior in all material classes, at all length scales above the atomic scale, both experimental as well as theoretical. Special emphasis will be placed during this colloquium on (i) understanding the microstructural mechanisms that lead to size effects (ii) capturing the size-scale dependent behavior in theoretical models, by using - experimental procedures, including advanced in-situ observation techniques - discrete microstructural modeling - enhanced (enriched, generalized) continuum modeling.

Schaumann University of Hannover Institute for Steel Construction Appelstrasse 9a D-30167, Hannover, Germany EUROMECH contact person: Prof. Hans Fernholz Website
  Information:	Central topics of the Colloquium will be the description of the atmospheric turbulent wind condition on different time scales, and the interaction of wind turbines with wind and water flows, which determine the turbine design, operation and maintenance. Topics of particular interest include: - wind climate & wind field - gusts, extreme events & turbulence - rotor aerodynamics & wake effects - sea states & wave loads - materials (composites, steel, concrete) & fatigue - structural health monitoring The aim of this EUROMECH colloquium is to bring together scientists and engineers from academic institutions and industry from all over Europe actively doing fundamental or applied research in the described fields of wind energy. The colloquium will be informal in character, without parallel sessions, and the number of participants will be limited. This will provide the basis for intensive discussions of the participants’ current research and for successful mutual exchange.

• [465] Hydrodynamics of Bubbly Flows

  Date:	6 June 2005 - 8 June 2005
  Location:	Lorenz Center Leiden, The Netherlands
  Contact:	Chairpersons: Professor Dr. Detlef Lohse Applied Physics, University of Twente Postbus 217, 7500 AE Enschede, The Netherlands Phone: +31-(0)534 898 076, Fax: +31-(0)534 898 068 E-mail: d.lohse@utwente.nl Prof. Leen van Wijngaarden Impact Institute, University of Twente Postbus 217, 7500 AE Enschede, The Netherlands EUROMECH contact person: Prof. Hans Fernholz Website
  Information:	With their ubiquitous occurrence in a multitude of fluid systems bubbles occupy a very important place in contemporary science and technology. One can readily cite a multitude of examples: the production and transport of oil (where bubbles are purposely injected to help lift heavy oil to the surface), energy generation (where boiling is the key process in producing the steam to drive turbines), the chemical industry (where gas-liquid reactors rely on bubbles to increase the contact area between the phases), the oceans (where breaking-wave generated bubbles are important sinks for atmospheric CO2), piezo-electric ink-jet printing (where they are just disturbing), bubble chambers in high-energy physics (where they used to signal the traces of energetic particles), and many others. Due to the improved experimental and computational techniques there has been rapid progress in the field in the last decade. E.G., simulating a few rising, deformable bubbles in still water is meanwhile possible. Also a lot of theoretical insight has been gained. However, many questions remain open. This holds both for a single bubble, e.g., what is the lift force on a single bubble in shear or rotational flow, and for many bubbles, e.g., how do many bubbles in turbulent flow modify the spectrum? Various experimental and numerical results on these questions have been obtained, but they often seem to contradicting to each other, presumably as the exact conditions are different. The idea of the Workshop at the Lorentz Center in Leiden and the Euromech Colloquium in the beginning of the Workshop is to bring together both experimentalist, theoreticians, and simulators of the fundamentally orientated bubbly flow community to allow for an exchange of ideas on the recent developments in this field.

• [468] Multi-scale Modelling in the Mechanics of Solids

  Date:	29 June 2005 - 1 July 2005
  Location:	St. Petersburg, Russia
  Contact:	Chairpersons: Prof. N.F. Morozov Institute for Problems in Mechanical Engineering Russian Academy of Sciences Phone: +7 812 321 4788, Fax: +7 812 321 4771 E-mail: morozov@nm1016.spb.edu Prof. I.G. Goryacheva Institute for Problems in Mechanics RAS Prof. M. Wiercigroch University of Aberdeen, UK EUROMECH contact person: Prof. I.G. Goryacheva Website
  Information:	The main scope of the Colloquium is to integrate and stimulate research interests in the fundamental constitutive modelling in mechanics of solids, in particular, to assess the progress in the fast growing area of multi-scale modelling in continuum and discrete mechanics. The topics include various approaches to modelling of complex media (e.g. mechanics of granular materials and fine cohesive powders, damage and fracture processes, phase transitions, moving boundaries and inhomogeneities in solids), micro- and meso- models (molecular dynamics, micro-contact modelling) combined with macro- models (continuum mechanics of solids, granular dynamics). The major difficulty in the description of media behaviour relates to their inherent abilities to undergo structural changes which are manifested with separation and rearrangement of particles, processes of damage and fracture, phase transitions (or moving boundaries) and inhomogeneities of various kinds. The solution requires an essential change in formulating constitutive equations describing evolution processes occurring in the medium. It is not only difficult to predict the dynamic behaviour of the medium, but even to determine characteristic parameters of the medium and to obtain robustly repeatable experimental data. This remains an unsolved scientific problem, and it is thought that a significant progress can be made if the Colloquium gathers a good mixture of theoreticians, engineers, and experimentalists, who can approach this problem by different methods and techniques. It is hoped that the Colloquium will consequently initiate and stimulate relevant discussions between different scientific schools.

• [469] LES of Complex Flows

  Information:	The intended scope is a review of the state-of-the-art of Large-Eddy Simulation (LES) of physically complex turbulent flows for which only LES can provide a sufficiently accurate prediction. The colloquium will address advances and current developments in improving existing and developing novel approaches to LES in particular with respect to wall treatment in large-Reynolds-number flows, coupling of RANS with LES, improvement of subgrid-scale modeling for geometrically and physically complex flow configurations, and the improvement of discretization schemes suitable for LES of complex flow configurations.

• [471] Turbulent Convection in Passenger Compartments

  Date:	13 October 2005 - 14 October 2005
  Location:	Göttingen, Germany
  Contact:	Chairpersons: Dr. C. Wagner DLR Göttingen, Bunsenstrasse 10 D-37073, Göttingen, Germany Phone: +49-(0)551 709 2261, Fax: +49-(0)551 709 2404 E-mail: claus.wagner@dlr.de Prof. A. Thess Technical University of Ilmenau, Germany EUROMECH contact person: Prof. W. Schröder Website
  Information:	Forced and bouyant convection in passenger compartments of automobiles, trucks, trains and in aircraft cabins controls the thermal comfort of passengers, the air quality and the transport of polutants and pathogens. To provide a comfortable and healthy compartment or cabin environment transportation and aircraft industries conduct intensive measurement campaigns and/or use Computational Fluid Dynamics (CFD) software for air and heat flow predictions. These CFD methods are not always able to reliably predict mixed turbulent convection. One of the reasons is, that CFD results depend on the accuracy of simplified physical models. These model are needed to account for not fully understood effects like turbulence, internal and solar heat radiation and the heat conduction within the human body. Therefore, there is a high industrial demand for a better understanding of turbulent convection in passenger compartments and for reliable computational methods, accurate measurement techniques and proper test facilities. It is the objective of the colloqium to focus on physical phenomena in turbulent convection and on numerical methods and experimental techniques needed to investigate flow and temperature distributions in passenger compartments and its effect on the passenger. Researchers from industries and research institutions should find a forum to discuss their problems and find possible solutions by launching new collaborations.

• [472] Microfluidics and Transfer

  Date:	6 September 2005 - 8 September 2005
  Location:	Grenoble, France
  Contact:	Chairpersons: Prof. Michel Favre-Marinet LEGI BP 53 F-38041 Grenoble, Cedex, France Phone: +33-(0)4 7682 5049, Fax: +33-(0)4 7682 5271 E-mail: michel.favre-marinet@hmg.inpg.fr Dr. Patrick Tabeling MMN ESPCI 24, rue Lhomond F-75231, Paris, Cedex 05, France EUROMECH contact person: Prof. Emil Hopfinger Website
  Information:	The development of microfluidic systems has grown rapidly over the past decade, generating a number of applications, some of them already turned into commercial products. In such systems, unusual lengthscales are involved (typically from 1 to 100 microns) and several new scientific questions arise. In particular, physical phenomena, negligible in flows of conventional sizes, may play an important role in microflows. Interface phenomena are especially important owing to the large values reached, in miniaturized systems, by the surface/volume ratio. Interface dynamics in microsystems, is a recent subject, interesting in its own right, and valuable to explore in view of controlling heat or mass transfer in microfluidic systems. At the moment, research studies currently investigate effects due to the coupling between microflows and geometry, wall slip, surface roughness, electrokinetics, variable fluid properties and conduction/convection. A substantial part of the research effort attempts to explore new fundamental processes, disantangling, in some case, their complex nature, along with exploring exciting new applications.

• [474] Material Instabilities in Coupled Problems

  Date:	30 August 2005 - 1 September 2005
  Location:	Troyes, France
  Contact:	Chairpersons: Prof. A. Benallal LMT-Cachan, 61 Avenue du Président Wilson F-94235, Cachan, France Phone: +33-(0)1 47 40 27 39, Fax: +33-(0)1 47 40 22 40 E-mail: benalla@lmt.ens-cachan.fr Prof. D. Bigoni Trento University, Italy EUROMECH contact person: Prof. P. Huerre Website
  Information:	Material instabilities are an important topic in the understanding of localisation and rupture phenomena. There has been a huge amont of work in this field in the last decades in solid mechanics, limited however only to the solid itself. There is a need in including in the localisation process various physical phenomena and their couplings to the mechanical behaviour of the solid. Thermal effects and thermo-mechanical couplings are one fundamental example. But corrosion phenomena, electromagnetic effects and hydromechnical effects are other important features that need to be incorporated in various applications. The main objective of the colloquium is to address these various couplings and their effects in the developments and growth of instabilities leading to localisation and failure in solids in the plastic and viscoplastic regimes. All physical couplings are welcomed. Also, all type are materials are included. Finally, the colloquium will consider experimental, modelling and numerical issues.
