Dear Colleague,
theIV European Conference on Computational Mechanics-ECCM 2010, Solids, Structures and Coupled Problems in Engineering, organized by ECCOMAS, will take place in Paris, France, May 16-21 2010 (see the Congress websitehttp://www.eccm2010.org/for more information).
During this conference, we are organizing a Minisymposium entitled:

With a generous gift from theHaythornthwaite Foundation, the ASMEApplied Mechanics Divisionwill award grants to students presenting their own work at the ASME International Mechanical Engineering Congress and Exposition (IMECE 2009). The grant will reimburse travel expenses and registration fees, up to $1,000 per student, for up to 10 students.

We study the scaling properties of forced folding of thin materials of different geometry. The scaling relations implying the topological crossovers from the folding of three dimensional plates to the folding of two-dimensional sheets, and further to the packing of one-dimensional strings, are derived for elastic and plastic manifolds. These topological crossovers in the folding of plastic manifolds were observed in experiments with predominantly plastic aluminum strips of different geometry.

We have one postdoctoral position, available in October 2009, in the general
area of fragmentation and dynamic failure. The specific interest is in the timescales and lengthscales associated with the interactions of failure modes in materials. A background in modeling and simulation is essential, while some experience with shock physics is desirable. The successful candidate will become part of a highly collegial and diverse research group with activities in nanomaterials, planetary science and biomechanics. The work involves collaborative research with the Johns Hopkins Applied Physics Laboratory, and US citizenship is required. If you are

I have one postdoctoral position, available immediately, in the general area of mesoscale modeling. The specific interest is in the development of computationally tractable models that incorporate the appropriate lengthscales and that can be used for microstructural design. The work is in conjunction with research groups involved in the development of materials for impact applications. Examples of topics of interest include the processes of dynamic failure in specific microstructures, and the development of physics-based models that account for grain size, grain size distribution, grain rotation and texture.

Hi all

I developed a Fnnite element code in Maple for Euler Bernoulli Beam Theory. Then I solved a cantilever beam with a vertical load at the free end. On comparing results with comercially available software, my results are good.

Finally I developd the FE formulation for Timoshenko beam theory. for the same cantilever problem, I introduced a small magnitue of shear modulus but the results are highly different from the Euler-Bernoulli beam.

Can any body explain this?

I got that there exist a property called ENTROPY;for which thedifference in it's values at two states is (Q/T).but I can't get it's physical significance

I know that it represents theirreversibility of the process.But it doesn't sutisfy me.So if anyone can...

Hi all,

I am currently working on mooney-rivlin materials. I wonder if someone have tried to compute GI, GII and GIII with the EDI because I don't understand how to compute WIII with mooney-rivlin.

Thanks a lot

My name is Aurelio Tronci and I am a PhD student at the University of Cagliari (Italy). My research topics are related to friction stir welding (FSW). The work done so far has focused on the application of the DOE technique in order to investigate the influence of welding parameters on the microstructural and mechanical properties of aluminum alloys (AA 2198 T3-T8) joints. At the moment I am interested in the development of a thermo-mechanical model of FSW with CFD, but I find it really difficult to find material constants (Sellars and Tegart law) for all the alloys I have to test.

We are seeking two post-doctoral researchers to pursue computational studies of polymer-derived high-temperature ceramics, which exhibit an unusual structure at the nano-scale. Projects involve quantum and classical molecular dynamics simulations, modeling structure formation and fracture mechanics, solid state and gas-solid thermodynamic processes, and oxidation behavior.

This has been a topic that the editors of Journal Club have been discussing for some time now. We would like some feedback from the entire iMechanica community.

The group Material Science and Simulations (Helena Van Swygenhoven) is looking for a PhD candiate perfoming atomistic simulations on dislocation/interface interaction. The group performs research in the structural and mechanical properties of metal, alloys and composites usingin-situtesting facility and is exploiding synergies with computational material science.

Due to the existence of surface stress, the interior of a free standing nanowire is in non-zero stress state especially near free surface (see attached). This stress state corresponds to strain field in nanowires. A reference configuration would then be necessary to define the strain. Any good suggestions on the selection of the reference configuration?

Leonhard Euler has 5 students and 56,850 academic descendents. They are all listed by theMathematics Genealogy Project. Euler himself was a student of Johann Bernoulli, and produced a student named Joseph Louis Lagrange, who in turn produced Fourier and Poisson. No wonder Euler has so many descendents by now.

一段时间我一直在思考我们如何组织nize a project to trace the genealogy of all mechanicians. It will be fun. It may even teach us some history of mechanics.

I am Cecilia. In 2007 I graduatedin mechanical engineering at the University of Cagliari (Sardinia, Italy).

During the degree courses I took several classes on structural mechanics, including, Mechanics of Composite Materials,

Fracture Mechanics, Finite Element Analysis (with Ansys and Abaqus).

Now I am a PHD student at the Univesity of Cagliari and this is the aim of my research:

Finite element modelling of polymer-clays nanocomposites with

I am currently working on a poroelastic model for an oil basin-I have tried and read through Abaqus manual to find out how we can apply Biot's Coefficient in our model or how it takes care of it-Does anyone have any clue about this?
