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.

Please see attached pdf for detailed information.

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 using in-situ testing facility and is exploiding synergies with computational material science. 

Dear All,

I would like to bring to your attention seven new research opportunities at the University of Oxford and at the Fraunhofer Institute in Freiburg (DE).

These are for four Post-Doctoral Research Assistantships (one at Oxford, three at Freiburg) and three PhD
Studentships (all at Oxford).

The details can be found here: http://www.eng.ox.ac.uk/NP/RESEARCH/VACANCIES/vacancies.html

Many thanks,

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?
