  • [556] Theoretical, Numerical and Experimental Analyses in Wood Mechanics

    Date: 27 May 2015 – 29 May 2015 
    Location: Dresden, Germany

    Information:

    Wood is one of the oldest materials used by mankind. Nowadays, it is of significance for a huge variety of applications starting from large span glue lam beams and load carrying components in civil engineering, up to for example music instruments as well as pressure, heat and moisture modified material for new, innovative products.

    Apart from the mechanical and aesthetical quality of the material, its eco-friendly features are of high significance. Thus, it can be assumed that the importance will even grow in the future.

    In order to be able to provide the desired, optimized components and to develop new applications, deep mechanical knowledge, theoretical modeling and numerical simulation approaches are required with respect to this complex material. Features to be identified are amongst others anisotropic elasticity, ductile plasticity, brittle fracture and time-, moisture- and temperature-dependency. Moreover, the material shows very pronounced features on different length scales so that it even could be described as a composite structure itself instead as a homogeneous material. The features depend on a large number of influence factors like growth conditions and yield a significant amount of scattering with respect to its properties. Due to this really large complexity and manifold dependencies, much research is required in order to be able to understand and to describe wood from the mechanical point of view.

    Even though science of forestry is a long established area of research, the mechanical analysis, modeling and simulation of wooden material is a relatively young field. 
    In the recent past, quite some effort has been undertaken in order to widen the mechanical
    understanding of wooden material from different points of view. Currently, lively and advanced research activities are under way in order to develop a comprehensive knowledge. In the past, wood mechanics was addressed by minisymposia within larger general conferences. The motivation of this proposal is to provide a dedicated forum for wood mechanics taking different methodologies into account and investigating at different length scales, either experimental or theoreticalnumerical.

    Basic research as well as application oriented aspects from industry should contribute to the mechanical description of this unique material. The exchange of ideas, methodologies and results in wood mechanics shall be fostered.

    Dresden may serve as an ideal location for this gathering of the scientific community in wood mechanics. It has a pronounced and unique profile within Germany in the field of research on forestry and wood. Here, research started about 200 years ago and is currently pursued in the faculties of Mechanical Engineering, Civil Engineering and Forest, Geo and Hydro Sciences. Moreover, the two chairmen of the proposed colloquium are contributing to this research field from different points of view over a long period of more than 10 years. At both institutes, major research groups are working very actively in the described field of mechanical research.

  • [559] Multi-scale computational methods for bridging scales in materials and structures

    Date: 23 February 2015 – 25 February 2015 
    Location: Eindhoven, The Netherlands
    Website: http://559.euromech.org/
    Contact:
    Information:

     In recent years, considerable progress has been made in bridging the mechanics of materials to the structural engineering level supported by advances in multi-scale modelling. Different classes of computational scale bridging methods have been developed to this purpose, spanning different disciplines, e.g. engineering, computational mechanics, mathematics, physics, chemistry etc. Although these methods have usually been equipped for a specific research problem, from a methodological point of view, similarities and distinctive features can be identified. Just a few examples include (i) methods that either rely on the separation of scales principle, or directly embed the fine scale model in the course scale one, leading to either nested or concurrent solution procedure; (ii) two-way coupling (fine-coarse and vice versa) or one-way (fine scale informed coarse scale model); (iii) the use of fine scale models for either extracting new emerging phenomena at the coarse scale, or quantification of the a-priori known coarse scale behaviour.

    This colloquium intends to serve as a forum for bringing together scientists from different disciplines working on scale bridging problems (both spatial as well as temporal) in materials and structures. The colloquium aims to identify common and distinct features of different techniques as well as their limitations and upcoming challenges, in order to stimulate and initiate an interdisciplinary cross-fertilisation.

  • [560] Mechanics of Biological Membranes

    Date: 8 February 2015 – 12 February 2015 
    Location: Centro Stefano Franscini, Ascona, Switzerland
    Website: http://www.euromech560.ethz.ch/
    Contact:
    Information:

    Fundamental studies in biology and medical research motivate investigations aimed at characterizing, understanding and modeling the mechanical behavior of biological membranes. Arterial walls, capsule of abdominal organs, amnion, eardrum, heart valve leaflets, skin are example of membranous tissue. Bio-membranes are essential constituents of biological cells. Bio-membranes inspire the development of synthetic materials and engineered tissues or implants with comparable mechanical performance (deformability, toughness) as the corresponding native tissues.
    The themes to be addressed include: (i) continuum , fiber networks, multi-scale models, micromechanical or statistical approaches to fibers-matrix interaction; (ii) experimental techniques for mechanical characterization; (iii) methods for the visualization of microstructure and mechanisms of deformation.

  • [562] Stability and control of nonlinear vibrating systems

    Information:

    The aim of the proposed Colloquium consists of bringing together scientists with interest in the topics of Structural Stability and Structural Control. In the past, several Euromech colloquia were held on these two topics but the two communities were kept separated. Bridging together the main results obtained on the common case-studies, such as flexible light structures and cables, might lead to interesting developments and will likely improve a common understanding of the state of the art, the latest trends, and the common terminology for both topics. The focus is placed on nonlinear vibrating systems, where nonlinearity arises from the large oscillations induced by external excitation of stochastic or deterministic nature
    on the studied mechanical system. Applications in these areas will be welcome, as will cuttingedge research in interdisciplinary problems involving civil, mechanical and aerospace engineering.

    Information:

    Dilute or dense suspensions of anisotropic (i.e. non-spherical) particles are encountered almost everywhere; e.g. aerosols in the atmosphere, microorganisms in the ocean, sediments in coastal areas and fiords, and wood fibers in the pulp and paper industry. The scope of the colloquium includes both studies and modelling of the behaviour of anistropic particles in turbulent flow fields, as well as the accompanying modulation of the turbulence field. The anisotropic particles can either be plate-like (e.g. flakes) or rod-like (e.g. fibers). The focus will be on generic aspects of particulate flows by means of computer simulations, laboratory or field measurements, or mathematical modelling. Topics included are particle motion in homogeneous or wall-turbulence; effects of particle shape and mass on particle orientations and distributions; particle-particle and particle-wall collisions; fluid-particle interactions; sedimentation of anisotropic particles; rheology of suspensions of anisotropic particles.

  • [567] Turbulent mixing in stratified flows

    Information:

    Understanding turbulent mixing is one of the outstanding central problems of physics, with applications throughout industry and the natural world. An important example of the latter is the downward transport of heat in the oceans from the surface to the deep abyss, a key factor in the oceanic storage of heat in the climate system. This transport is driven by turbulent processes that must overcome the stable vertical stratification that inhibits vertical motion. Exactly how this occurs is not known, and even in idealised flows our understanding of the turbulent dynamics does not allow us to predict vertical fluxes from the mean fields. Consequently, turbulent transport is represented in an approximate way in climate models and this leads to substantial uncertainty in their predictive capabilities. This is fundamentally a problem in stratified turbulence that also has application in industrial processes and other environmental problems such as the transport and fate of pollution.

    Recently there have been significant theoretical advances in unstratified turbulence coupled with extensive computational and laboratory studies. The aim of this conference is to explore the application of these techniques to stratified turbulent systems. We anticipate that bringing together a group of experts with widely varying backgrounds will ultimately lead to significant advances in the understanding of stratified turbulence and the development of models for practical applications. Pursuing this important and wide-ranging objective will require testing the theoretical predictions using experimental and direct numerical simulation (DNS) data that are beginning to be collected.

    The colloquium will discuss the relevant oceanographic, atmospheric and industrial flows applications along with sessions discussing the theoretical, experimental and computational aspects of this topic. The latest results in both unstratified and stratified turbulence will be presented with the view to developing a holistic approach that links experiment, calculation and theory in the quantitative combination needed to gain the insights into the dynamics.

  • [568] Coherent structures in fully developed turbulence

    Information:
    It is widely agreed that coherent structures carrying a substantial share of the Reynolds stresses are important ingredients of free-shear turbulent flows, where they have led to applications such as improved control. The issue is less clear in attached wall-bounded flows, such as pipes, boundary layers and channels, whose mean velocity profiles lack known inertial modal instabilities.
    However, the past quarter century has seen numerous proposals of simplified models for dominant structures in those cases, including exact travelling waves, orbits, linearised transients, and hairpin packets. Most of these structures are known to be important in transition, but less is known about whether they are present in fully developed wall-bounded turbulence in the same sense as in the free-shear case. Although it is all but certain that none of them can be found exactly in a fully turbulent flow, the interesting 
    question is whether some approximation can be found, approximation metrics can be defined, and quantitative information obtained about how close and how often a turbulent system comes to any of them. The purpose of this colloquium is be to bring together researchers working in the identification of simple models with the owners of turbulence data bases, to try to define what needs to be done. There are by now enough candidate structures, and enough temporally and spatially fully resolved DNS data bases, that such a program is beginning to be possible. 
     
  • [570] Multiscale analysis of the impact of microstructure on plasticity and fracture in interface-dominated materials

    Information:

    The microstructure of materials is known to have a dominant influence on their mechanical behavior - often larger than the chemical composition. The understanding and the prediction of the link between the microstructure and the deformation and fracture mechanisms, analyzed at different length scales and from different scientific fields, are the main targets of this colloquium. Multiscale must be regarded in a bottom-up approach where atomistic calculations provide information for the formulation of larger scale constitutive laws or cohesive models. Such interfaces include, among others, grain, twin and phase boundaries, precipitates and cracks inside the material, free, corroded and anodized external surfaces of the material.

    The colloquium will gather scientists from different fields related to the description of interfaces in order to make bridges between materials science and solid mechanics, between molecular/atomistic calculations and continuum descriptions. All the contributions dealing with the understanding or the prediction of the influence of interfaces on the competition between plastic deformation and fracture are welcome. Both experimental and modeling studies will be mixed together in order to stimulate discussions and interactions

    Information:

    The development of more economical and safer societies requires to improve the means of transport and of energy production. Among these means, rotating machines hold a central place. To address these societal issues, it is then essential that the rotating machines technology be innovative and make progress on the following topics: performance, costs and noise reduction while continuing to maintain the components’ reliability, durability and safety.
    Thus, the purpose of this colloquium is to promote exchange in the rotor dynamic community around their most advanced research in coupling and nonlinear dynamic. Papers are solicited in all aspects of nonlinear dynamics or coupling in rotating machinery. The main objective is to have a state of the art in nonlinear numerical (or analytical) simulation (or analysis) tools applied in the field of rotating machinery associated or not with experiment. Concerning multi-physics coupling phenomena, it is mainly the aspects of stability and nonlinear behavior which will be developed during this symposium.
    Applications with laboratory and field investigations are welcomed.
    The topics of interest include, but are not limited to, modal testing and identification, dynamic stability, nonlinear phenomena, arametric excitations, interactions (e.g., rotor-stator, torsionbending, fluid-structure, and electromechanical), active and passive control techniques, disk assemblies, and case studies.

    Information:

    Advanced mathematical models, computational schemes as well as experimental techniques inspired by moving load problems are addressed. The colloquium is aimed at bringing together multidisciplinary expertise originating from diverse application areas. These include but not limited to the impact of high-speed railway transport on the environment, optimization and control of road vehicle systems, and harvesting of energy by moving sources.

    The increase in the speeds of the loads motivates more elaborate analysis of resonant regimes, e.g. related to approaching the surface wave barrier. There is also a clear demand on general three-dimensional models, instead of simplified plane schemes which used to be wide spread for moving loads problems.

    Three-dimensional dynamic modeling is one of the main focuses of the Colloquium. The modern computational technologies enable numerical analysis of various sophisticated setups taking into consideration realistic physical properties of the environment including anisotropy, pre-stress and layered structure, as well as a proper account of the geometry of moving objects. At the same time recent developments in the area of nearsurface elastodynamics, in particular, the specialized hyperbolic-elliptic formulations for Rayleigh wave fields drastically simplify the qualitative and quantitative analysis of the dynamic response due to moving loads. This makes possible a comprehensive approach to a number of practically important moving load problems.

    Information:

     Composites materials consist basically of two or more phases and are designed in such a way to produce desired properties for engineering application, e.g., in metal ceramic composites it is possible to combine the ability to undergo plastic deformation of the metal with the temperature resistance and hardness of ceramics. Among them there is a big class of advanced composites, functionally graded materials (FGMs), with a continually varying composition in a spatial direction and, accordingly, with continuous varying properties in this direction. The mechanical behavior of composites is evaluated on both microscopic and macroscopic scale levels to take into account inhomogeneities and interactions between inhomogeneities. Metal ceramic composites are applied in different fields, such as, nuclear energy (e.g. nuclear reactor components), aerospace (e.g. rocket engine components, space plane body), engineering (e.g. turbine blade, engine components), energy conversion as well as other applications. They are subjected to different thermal and mechanical loadings and have to resist high temperature, wear and aggressive environments which strongly influence the composite behavior and degradation. Cracks can initiate from initial defects or microcracks and appear during manufacturing or service. Therefore, the study of fracture of metal ceramic composites and structures is important for a better understanding of the fracture resistance of composite materials.
