Discussion of fracture paper #41 - Are dislocations good or bad guys? It depends!
Around Shifting from macroscopic to microscopic plasticity helps us understand mechanisms that can help us develop high-strength metallic materials. Things that prevent dislocation dynamics or generation, such as other dislocations and grain boundaries in polycrystalline materials, lead to higher strength.t...

Linear Instability Signals the Initiation of Motion of a Twin Plane Under Load
by Chang-Tsan Lu and Kaushik Dayal
Abstract
I have extracted field output from ABAQUS odb file and I want to take log of that field. In ABAUQS scripting manual, in section 9.8.2 it has been mentioned that
log10(field output)= field output
When I am trying to do this compilation gives me error. "a float value required"
Please guide me if i am making any mistake
Also if possible, suggest how can I get rid of this problem?
I'm currently studying FEA/CFD and BEM for thermal simulation of custom dies within custom package mounted on custom PCB with encapsulate material (epoxy). I getting familar with CFD concept which seem overkill from ANSYS IcePack (too expensive) but exploring BEM technology from E3D in france (via Vishay).
I have access to MATLAB from other company to try it out for thermal modelling (BEM).
There are many job positions on hardware reliability due to the success of on xbox Kinect. The following is the typical description. Please check out http://www.microsoft-careers.com for more.

i'm in my first year of doctorat level, and i work on meshfree methods applied in mechanical field, i would ask for recent research in this field and some indications for : what new to explore (composit materials, crack and fractures, other new materials...) in this field
Hello everybody,
I just wanted to let those interested in Matlab finite element development and educational environments that the successor to the SOFEA toolkit is now available at
http://hogwarts.ucsd.edu/~pkrysl/faesor
The toolkit now provides in addition to thermal and stress analysis (static and dynamic) also sample simulations from other fields, such as acoustics, nonlinear heat conduction analysis, electrostatics, small-strain plasticity, .... The toolkit now also includes an implementation of the Nodally Integrated Continuum Elements (NICE) which are quite effective for nearly incompressible mechanics problems.
The toolkit and the accompanying textbook are open-source and freely available. The book is also available in print.
