Looking for suggestions and comments on PhD research Project
Dear Researchers and Industry Engineers,
In this letter I am looking for some comments and industrial supports for my PhD research on non-contact measurement for machinery maintenance.
Mechanical threshold stress model for 6061-T6 aluminum
Our paper on the Mechanical threshold stress (MTS) model for 6061-T6 aluminum has been accepted by JoMMS. There are several things of interest in the paper:
1) The use of a phonon drag model to predict the sharp increase in flow stress at strain rates above 10,000 /s. This behavior is seen in a number of materials and is hard to fit using standard power law plasticity models. Our model does a good job in this regard.
Call for Minisymposia and Sessions at EM08
If you are a faculty member on the tenure-track or a post-doc it's a good idea to chair a few minisymposia at conferences to buttress your resume. Here's an opportunity for you:

Interfacial moisture diffusion using cohesive zone elements
Hello every body,
As most of you know, fracture mechanics of polymer materials needs a special consideration of the viscoelastic material properties. Especially under thermomechanical loading the role of glass transition temperature T_g is very important. That is why people try to characterize the material with different methods including stress relaxation based on Time-Temperature superposition or DMA test.
Opening for PhD Student in Computational Science and Engineering at Rensselaer Polytechnic Institute (RPI)
Opening for a PhD student in the area of large scale parallel computing and optimization with applications to high resolution lithography. The research will be a part of the Computational Center for Nanotechnology Innovations (CCNI) at RPI and will make use of one of fastest computers in the world (http://www.rpi.edu/research/ccni/) . The project will be supervised by researchers from RPI, IBM and the Woods Hole Oceanographic Institute (WHOI).

Naming the SI Unit for Fracture Toughness (KIC)
To: Engineers, Fracture Analysts, Mechanicians, Physicists...
In science and engineering, we have an excellent tradition: naming a physical unit using the name of a prominent personality from the concerned field. For example, in SI system, we measure force in newton, work in joule, power in watt...
But the unit of fracture toughness, i.e. KIC, is too lengthy to pronounce: (mega) pascal-underoot-meter. Further, it has also been in use for something like half a century by now, perhaps more. So, how do you like the idea of giving a name to this unit?
