Two PhD student positions at Particles and Grains Laboratory, The University of Sydney, Australia
 
The research project is concerning the micromechanics of granular materials, which include time-dependent deformation of geo-materials, thermal-mechanical behaviour at elevated temperatures, and transport phenomena in porous media. In this project, the main objectives are to characterise and understand fundamental deformation mechanisms from the grain level, and develop material models with grain-scale information with multi-scale approaches using simulations and experiments.

A research position is now opening in the field of Computational Mechanics of granular materials, in Karlsruhe Institute of Technology (KIT), Germany. This position should start between May and September 2010, and is a full-time fixed-term PostDoc position for 2 years (TVL E13).

I am now going to model a sample with metallic glass (Cu-Zr-Ti) under stress and temperature loads. I wonder whether there is some existing database to find material properties, in particular, the creep properties with respect to temperature and stresses. Then I can use these data as input for a FE analysis.

Thank you very much!

Last time, when I saw one blog of Biswajit Banerjee, I thought it would be much more convenient if we can input some equations in iMechanica for discussion. When I make discussion about mechanics with colleagues, I would like to write down some equations on the blackboard or paper. For discussion based on the web blog, LaTeX equations will be helpful. And it would be better if one can input equations directly instead of uploading one picture after another.

More than fifty years ago, people realized that we can use fusion for energy, but the problem remains where and how to keep a plasma of 100 million degrees centigrade.

For TOKAMAK, one of the approaches to use the fusion power, now comes the news: "On 21 November, Ministers from the seven ITER Parties came together to sign the agreement to establish the international Organization that will implement ITER."
