Viscoelasticity can be studied using Dynamic Mechanical Analysis (DMA) during Nanoindentation. By applying controlled oscillatory stress the resulting strain can easily be measured. An elastic material will have stress and strain in phase while a viscous-elastic material will have strain lagging stress. In many applications during quality control and R&D, it is important to reliably test this behavior.
Respected sir/Madam,
I am Devarajan.K Doing M.Tech Engineering design . I am currently doing projects in Optimisation of influence of rolling paramters in cold rolling process . For this i choosed the following input parameters of rolling process
1. Roller Diameter
2.Roller Speed
3. Friction Coefficient
4.Inlet material thickness
5.% of reductions
I was pointed to this article, which was a good read. A link to the article in PDF is also provided here (author's home page).
The European
Research Council funded RealTCut Research Group is seeking three Research
Assistants/Associates over a 5 year period on project: “Towards real time multiscale simulation of cutting in
non-linear materials with applications to surgical simulation and computer
guided surgery.”
“ERC grants aim to support
"frontier research", in other words the pursuit of questions at or
beyond the frontiers of knowledge, without regard for established disciplinary
boundaries.”
You will work on nanomechanical modelling of contact, friction and molecular
adhesion at the nano/micro-scales under the supervision of Prof. F.M. Borodich and
Prof. H.P. Evans. The studies will be applied
to nanotribological systems that are governed by the physical processes applicable
at the nanoscale. These include adhesion caused by van der Waals interactions
and capillary effects, and various surface effects. Fundamental understanding
The proof of
Saint-Venant's Principle for curved bars is discussed and the formulation of
Modified Saint-Venant's Principle of the problem is established. The study
shows that Saint-Venant's decay of stresses is valid only for the curved bars
which are “effectively infinite”. It is essential and significant to develop
A new post-doctoral position is open for conducting cross-disciplinary basic research in the theory of heterogeneous structural materials. Candidates are sought with strong background in statistics or statistical mechanics, probability theory, and mechanics. A Ph.D. in Mathematics, Physics, or Engineering might be appropriate.
