Postdoctoral Position Opening at Stanford University
Prof. Wei Cai at the Mechanical Engineering Department of Stanford University is seeking a postdoctoral researcher to lead a project on the modeling of grain structure evolution in the surface layer under friction. The major task of this project is the development of a phase field model for grain/sub-grain structure evolution under friction. It is likely that molecular dynamics and dislocation dynamics simulations would be required as well to obtain a good physical understanding of the process.
Numerical implementation of static Field Dislocation Mechanics theory for periodic media

(to appear in Philosophical Magazine)
Two Post-doctoral Associate Positions Available at Rice University
Position Description: Two postdoctoral associate positions, one in computations and one in experiments, are available at Rice University. The first position is in the area of atomistic and molecular modeling of nanoscale defects, dislocations and mechanics of complex, low symmetry compounds. The computational techniques will be integrated to approaches from statistical mechanics and physical chemistry to provide quantitative predictions of properties of complex materials across different time- and length-scales.
Full scholarships available at European Commission funded workshop on physics based material models in Izmir / Turkey
European Commission' s JRC (Joint Research Centre) is organizing the 3rd workshop on physics based material models and experimental observations (http://iwpmeo.org/) in collaboration with University of Oxford, Max-Planck-Institut für Eisenforschung and Middle East Technical University. The workshop will be held in Izmir/Turkey on 2-4 June 2014.

search for Petch's classic paper entitled "The cleavage strength of polycrystals"
Recently, I am reading several classic works on crystal plasticity. But, it seems to be difficult for me to obtain several very old papers in this area. For example, one of the classic papers on Hall-Petch relation,
Petch, N.J., The cleavage strength of polycrystals. The Iron and Steel Institute, 1953, 174: 25-28. I have tried many ways to get the original paper, but I finally failed. Could someone please send me a copy of this paper? Thanks a lot. Here is my email: dbliu2009 [at] gmail.com
Post-Doctoral Opening on Multiscale Modeling of Materials
We are seeking to hire outstanding candidates for a post-doctoral research position in
the Koslowski’s group at Purdue University to work on dislocation dynamics and/or
continuum modeling of plasticity. The project involves developing and applying
numerical methods to study creep and plastic deformation in nano and ultrafine
crystalline materials. Successful candidates will have the opportunity to interact with a
wide range of experimentalists and theoreticians in academia, industry and national labs.
Post-doc Position in Atomistic Modeling at Rice University
A postdoctoral associate position is available at Rice University in the
area of atomistic and molecular modeling of nanoscale friction and defects in an assembly of
nanoparticles. Computational techniques will be integrated to approaches from statistical
mechanics and physical chemistry to provide quantitative predictions of properties of complex
oxide materials across different time- and length-scales. The research will be carried out at Rice
University's Multiscale Materials Modeling Lab.
Royalty Free Illustrations
Does anyone know of a good source for free science and engineering illustrations? I'm particularly interested in crystallography, crystal defects/dislocations, and mechanical properties illustrations.
Thanks
