| Information: | The pioneering mechanical models dedicated to the metals fatigue under cyclic loadings were macroscopic. Today, it is well accepted that the mechanisms underlying crack initiation start at the scale of dislocations. In the last two decades, researches have attempted to extend the experimental basis in this sense and to introduce this view in the modelling. The experimental objective was to obtain information at the relevant scales (dislocations structures, slip bands, grains) by using complementary leading edge techniques: Transmission Electron Microscopy, Scanning Electron Microscopy with Electron Back-Scattered Diffraction, Atomic Force Microscopy, etc. The theoretical and computational objectives were to compare and integrate observations in multiscale physically based models, as polycrystalline aggregates calculation or Discrete Dislocation Dynamics simulations. From the engineering point of view, there were some attempts to include these works in state-of-the-art fatigue predictions on structures but further effort should be provided in order to use these models on a day to day basis. As a consequence, most of the recent developments are realized at the border between the communities of metallurgy, theoretical mechanics and mechanical engineering. The purpose of the colloquium is to organise a meeting where these communities of matirials, theoretical mechanics and mechanical engineering can exchange state-of-the-art modelling and results on the multiscale mechanisms and mechanics in fatigue of metals. We expect that this cooperation should lead to openings of new complementary research fields, intimately coupling theoretical and numerical tools with new experimental resources. The topics discussed during the colloquim are:
- experimental complementarities between TEM, SEM with EBSD, AFM and new opportunities offered by kinematic and/or thermal full-field measurements and acoustic emission at micrometric scales which enable the study of the forerunner signs of fatigue damage.
- numerical tools including Polycrystalline grain modelling and Discrete Dislocation Dynamic which are of great interests in crystalline plasticity for the definition of multiscale fatigue criteria.
- multiscale fatigue criteria and structural computations
The application of these models and techniques will be illustrated on different fatigue contexts: isothermal or non-isothermal, uniaxial or multiaxial loadings, contact and/or fretting fatigue, constant or variable amplitude loadings. Within the topics, a special attention will be accorded to complex cyclic loadings as well as to new metallic materials and/or structures. |

| Information: | Dynamics of non-spherical particles in fluid flow are encountered both in nature and in industrial applications, e.g. airborne solid particles or aerosols, carbon nanotubes, micro-organisms like phytoplankton, sediment-laden flows and wood-fibre suspensions. The scope of the colloquium includes both studies and modeling of the dynamical behaviour of non-spherical particles as well as the modulation of the turbulence field brought about by the particles. The focus will be on generic aspects and physics of particulate turbulent flows, be it computer simulations, laboratory or field measurements, and theoretical studies. Among the topics to be included are particle dynamics in free and wall-bounded turbulence, fluid-particle interactions, collision modelling, agglomeration, advances in measurement and simulation techniques, and rheological modelling. |

| Information: | The methodology of the Multibody Systems Dynamics, although being a subject of the theoretical and applied mechanics, encompasses particular approaches to solution of complicated tasks for analysis of systems of rigid and flexible bodies that implement complex motion in the environment. Multibody Systems Dynamics has recently established itself as a particular branch of engineering science. It could be observed that the theoretical basis is already developed but powerful tools for analysis, simulation, and design of complex mechanical systems are not yet in the hands of the scientists and practitioner engineers. Nowadays scientists and engineers are faced with problems related to the mathematical methods and numerical algorithms that constitute the basis for multipurpose computer simulations and real time motion simulation (virtual environment) of rigid and flexible multibody systems. Path planning and motion control of flexible systems, active and passive vehicle control, and vibration suppression are technical challenges that require tailored methods and advanced algorithms for the dynamics simulation. Examples for future applications of advanced simulation techniques include large flexible structures exposed to earthquakes and natural disasters, smart structures, marine systems, construction machines and large vehicles in general. Aeronautics and space engineering in particular rely on accurate numerical simulations that are the basis for motion control such as reorientation and maneuvering. Space systems are also subject to dynamic restrictions and design constraints that need to be taken into account during the design process. Manipulators, robots and autonomous walking machines operating in hostile environment and underwater are also targeted applications of the multibody system dynamics methodology. Concepts from multibody system dynamics can be applied in biomechanics, medicine and surgery. In fact, they have been successfully applied for the analysis of medical and biomechanical problems, and gave rise to novel analysis tools and technical applications. At the colloquium theoretical advances and numerical methods for the generation of dynamics equations and their solution will be discussed. Special emphasis will be given to the virtual realty algorithms and real time simulation. Their application to Robotics, Mechatronics and Smart Systems, Vehicle Dynamics, Aeronautics and Space Structures, Solid-Fluid Interaction, Biomechanics and Medical Applications will be visible from the anticipated presentations. New ideas, future trends and areas of applications will be discussed. Another aim of the colloquium is to provide a platform and a productive atmosphere for exchange of new ideas and experiences between teams and experts in the filed, as well as to create the basis for further developments and collaboration. Topics:
- Advances in Dynamics Formulation and Real Time Motion Simulation;
- Robotics, Mechatronics, and Smart Systems;
- Vehicle Dynamics;
- Aerospace and Space Applications;
- Solid-Fluid Interaction;
- Biomechanics and Medical Applications;
- New Systems and Areas of Application.

| Information: | Recent research has shown that a layer of strong shear may act as a barrier for eddies and prevent it from penetrating through that layer. These shear interfaces, because of their persistence, have a major importance on the flow dynamics because of their impact on transport of heat, mass and momentum. Over the past decade, their relevance has been recognized in a variety of different flows. In atmospheric flows the edge of the polar vortex is known to act as a barrier for the transport of ozone depleting gases; in turbulent boundary layers transport is blocked according to the same mechanism. Layers of shear are equally formed in planetary atmospheres (e.g. Jupiter , known as PV staircases), in plasmas (e.g. Tokamaks, Sun), transport barriers play a dominant role for the flow dynamics and explain anomalies observed in energy spectra. The aim of this meeting is to bridge these traditional research disciplines and to discuss interfacial processes which occur in a diverse areas of fluid mechanics. |

| Information: | Biomechanics play an important role in the functioning of the eye, in both health and disease. The eye is a complex organ with its own fluid production and drainage mechanism, internal vascular system and internal and external musculature. The importance of this research area is evident from the large number of researchers worldwide, and also demonstrated by the existence of Ocular Mechanics sessions that have run for several years at the ASME Summer Bioengineering Conference and the Ocular Biomechanics Symposium at the Annual Meeting of the Association for Research in Vision and Ophthalmology 2008. |

| Information: | Rotation and buoyancy play an essential role in many geophysical, environmental and industrial flows. It strongly affects the flow properties such as inducing anisotropy of the flow and dramatically changing the turbulence properties. This inevitably has a strong impact on the dispersion of passive and active tracers and (inertial) particles in such flows. The aim of the Colloquium is to bring together researchers with interests in theoretical descriptions and numerical studies of the mixing and dispersion properties of rotation and buoyancy dominated flows, and experimentalists on rotating, stably stratified and buoyancy-driven flows, respectively. Satellite and field observations play an essential role in mixing and dispersion studies of large-scale geophysical and of environmental flows. It is intended to encourage colleagues from this field to contribute to the Colloquium. Topics of interest range from the fundamentals of mixing and dispersion in canonical systems such as vortices in rotating or stratified fluids, but also homogeneous rotating or stratified turbulence, to mixing from an Eulerian/Lagrangian point of view in geophysical, environmental and industrial flows. Special attention will also be given to interdisciplinary topics where fluid mechanics and mixing are central themes. Some examples include the (large-scale) dispersion of marine species in oceans, estuaries and lakes, mixing in drinking-water supplies, transport in rivers and estuaries, and ventilation, comfort and safety aspects in buildings and public transportation systems. |

| Information: |
The main aim of the workshop will be the presentation of the more recent advances on high Rayleigh convection associated with large space for discussions and collaborations between different communities. This High Rayleigh number Workshop is the 4th after Ilmenau (2000), Leiden (2003) and Trieste (2006). The previous workshops always had an informal character with space for discussion and interaction and a lot of progress have followed in the years past the meetings. Another goal is to try with this workshop to put together some of the different communities interested in the subject.
Main topics: • thermal convection in rotating flows, • ultimate regime in Rayleigh Bénard convection • convection in non Boussinesq flows • low and high Prandtl number flow • convective mixing • large scale flow dynamics |
